[Michael]
Where is everyone? We have been listening
for messages from outer space for more than half a century, and so far… silence. Why? Are we truly alone
in the universe? Or is everyone else
acting like us and just doing a lot
of listening? Maybe we need to be louder. Maybe we need to send
more messages out there. But how do you write a letter
to an extraterrestrial whose language and culture
and biology and mind we have no concept of? And what do you say? And given all of the unknowns
about what they might be, should we say
anything at all?♪♪Ever since I was a kid, I’ve wanted to design
a message that is sent
to outer space. A sort of hello from Earth
to whatever extraterrestrials might be out there. I mean, come on, to be
the author of the first thing aliens ever heard
from our entire planet would be a fantastic honor. And as it turns out, an opportunity to send
a message to space has been given to me. But it might
be a waste of time. What if there isn’t anything or
anyone out there to receive it? The fact that we still have
no evidence of intelligent alien life despite the high probability
that such life exists, is called the Fermi paradox. And there are many
entertaining theories that attempt to explain it. One explanation
is the theory that whenever two
civilizations meet, destruction always results. Which is why in 2015, several prominent experts
wrote a letter warning against making
any contact at all. [Stephen Hawking] Ideas like that suggest that
perhaps we should remain silent, send no messages to space. But Doug Vakoch
disagrees. He is the president of METI, an organization that,
despite all of these concerns, is nonetheless
actively messaging extraterrestrial
intelligence. If I want to design a message
for life out there, I should talk to him first. Why isn’t he afraid?I met up with Dougat the Chabot Observatory,home to the largest
public refractor telescopein the Western United States.-[Douglas] So here we are.
-[Michael] Wow. [Douglas]
Yeah. This was one of the prime
telescopes of a century ago. This is really an antique. [Michael] Jeez!
I’ve seen so many observatories and so many big telescopes
in pictures. Believe it or not, I’ve never
been this close to one. [Douglas]
This is a huge instrument, and yet it’s balanced
too exquisitely. I’m like a super person.
Oh! [Douglas laughs] It had quite a bit
of momentum there. I’m scared to look. I’m telling you, I had no idea
I would have this feeling, -seeing a telescope this big.
-[Douglas] Well, it is, it is. Can I handle
what I would see? I think you can.
I think you can. You just take a look. Ah-ha. -Absolutely nothing.
-[Douglas] Not tonight. -Because of the fog.
-Because of the fog. [Michael]
Just the fog coming in
is pretty darn cool.The universe has existedlonger than we have,but we’ve only been actively
listening for life out therefor the last half century.In 1960, astronomer Frank Drake
began the searchwith a 85-foot radio
telescope.He scanned for interstellar
radio waves,but did not detect
any recognizable signals.Soon after, SETI, or Search for
Extraterrestrial Intelligence,was formed to continue
our searchfor other life
in the universe.[Mission Control]
Liftoff.[Michael]
Besides just listening,we’ve also launched
physical messageslike the Golden Records
we put aboardboth Voyager spacecraft
in 1977.The records were recordings
of images and sounds from Earththat told a story of who we are
as Earthlings,as well as coded instructions
on how to play them back.Today, Doug and his team
at METIare on a mission to send
new messages to the stars.Thank you for taking some time
to have a conversation with me. My first question
is simply this: where is everyone? Are we alone? I don’t think so. You know, we’ve been looking for over 60 years. And so that leads some people
to say we must be alone. The reality is, though, we have just
begun the search. I mean, we’ve looked at a few
tens of thousands of stars, and there are 400 billion stars
in our galaxy alone. Billions of galaxies
in the universe. So I think we just need
to keep on looking. When you put it that way, it actually isn’t
that surprising, is it? I mean, we are still discovering
species on our own planet today. At METI, we switch the process, and instead of just listening
for signals, we send powerful, intentional
signals to other stars in the hope of getting
a reply. What do you say
to people who go, “Hold on, “we should not be alerting any
life out there to our presence. “It’s just not worth the risk. In fact, it’s irresponsible.” I would say it is too late. The horse is out of the barn. We have been announcing
our presence to the universe since the beginning of radio
and television. Any civilization
that has the ability to travel between the stars already picked up
I Love Lucy.So maybe the aliens
have been observing us, but they’re waiting for us
to break the silence. So our goal isn’t
to let them know we’re here for the first time. It’s to really give
an indication that we want
to make contact. The one thing that’s keeping me
from being really excited and comfortable
about sending a message out is that a lot of prominent
people have said, “Don’t.” There are some group
of scientists who have said you shouldn’t be doing this. Stephen Hawking. But that’s an example
of someone very prominent who said you shouldn’t transmit, because maybe the aliens
will come to Earth. To me it’s notable that,
after his death, to commemorate his life,
his family, they transmitted his voice
out into space. Anyone and everyone can
transmit to extraterrestrials. So I think it’s an incredible
contradiction for people involved in SETI
to say we shouldn’t transmit, because the day they succeed,
everyone will be transmitting. Okay, so how do we craft
a message for E.T.? Well, it depends
what we would want to do. I would want to know something
about that civilization. And so then we try
to figure out, what is it that we have
in common with the extraterrestrials? What do you think the aliens
would know that we know? I always go to math. So that’s the natural
starting place. But how can you communicate
the idea of numbers? Like this. [both clap] -Hey, look, we’re communicating.
-Okay, okay, great, great. You could keep that up.
You could use that to count up to a million. But that doesn’t capture
what it is to be human. Right. So you want to tell
a little bit about yourself. The goal, for me, is to learn
about other civilizations if, in fact,
they’re out there. But I think
even if they’re not, simply this process
of reflecting on what stories do we want to tell
about ourselves, how do we want to represent
ourselves to the universe, forces us to look
at ourselves anew. And I think that
can only be good. One of my favorite messages that humans have ever sent
for extraterrestrials to some day receive
was written in 1974 by Frank Drake
and Carl Sagan. They sent the message to a star
cluster 25,000 light years away. It contained 1,679
binary digits that, when decoded, created an image: the famous Arecibo message. This message is full of general
information about us. Up here in the white
are numbers. Now, since math is probably
pretty universal, I feel like it’s fair to say that aliens will understand
that part. But what about some of these
other parts? This is a human figure,
but will aliens be able to tell that that is supposed to be the shape of the thing
that made this? Could an alien figure out
what all these symbols mean? For that matter, could a human
even correctly figure out what they all mean? And I bet that if you were
to ask two people to guess what all this means, you would get
two different answers. I want to give some humans
a message, and I want to see how quickly
they come up with meanings I didn’t put in there,
or conflicting interpretations, because if that happens, well it could spell trouble
for our ability to say much more than simple mathematical truths
to whatever might be out there.To help me answer
this question,I recruited Dr. Steve Vance.Dr. Vance leads
a habitability teamfor JPL’s Astrobiology group,meaning it’s his job to think
about the possibilityof life on other planets.I don’t think it’s crazy that if the Arecibo message
is received, the alien civilization
that gets it will see all kinds
of meanings in it. They’re going to see things
through the lens of how they experience
their world. And I think if we received
a message from outer space, we would think of the ones
we’ve sent out, and we would look
for these pieces in it. And maybe the message
contains none of those things. I’m really curious
about this hypothesis that they will find meaning
where there isn’t any. There’s only
one way to find out. -Yeah. Let’s do it.
-Let’s do it. [Michael]To find out how
individuals’ own backgroundswould influence their approach
to a message from space,we sought out
a veritable A-teamof critical thinkers
and problem solversto put to the test.I’m a sophomore engineer,
and I have a PhD in physics. I’m a game designer
and programmer. I am a professional
poker player. I’m a graphic artist
and app coder. I teach college courses
in writing film and psychology.This set of experts
would be toldthat the message
they were receivingwas intercepted
from outer space,and would be asked
to decode itusing a variety
of office suppliesand computer software.What they didn’t know is thatalthough similar to
the original Arecibo message,our message is just noise.Would our group
of experts noticethat there was nothing
to get,or apply their own meanings
to this indecipherable message?It was time to find out.We received a message using a radio telescope
from outer space. Not the kind of thing
that naturally happens. What we want to know
is what it says. A copy of the message
as received is on that laptop. This is an audio output
of that message. Using your individual expertise and the tools
that you have in front of you, please figure out
what this message is saying. This is not an easy task. -Okay.
-Good luck. -Okay, you ready to listen?
-Let’s hear it. Here we go. [pings]Before the team
can interpretthat our jumbled image
is meaningless,they first have to figure out
that they’re supposedto decipher it visually.This would be the first step
for any alien civilizationwho received the real
Arecibo message.To do that, the first step
is to recognizethat it’s binary.There are two different tones
in the message.[man] Is there a difference
in time between any of these? [woman]
It doesn’t look like it.
The rhythm doesn’t vary. [man]
It doesn’t vary? There’s going to be a repeating
pattern in there, probably. It seems like
there’s only two notes. Yeah, it doesn’t seem to go
any higher or lower than that. So there’s only two tones.
We’re thinking some kind of binary message,
zeros and ones, We should probably
start transcribing itand look for repeating
patterns.Right off the bat,
all right? They’re noticing two tones,
binary message. I think that’s a very
human thing to do, because we already
come to this knowing that binary is this
great way to talk, right? So we’re already seeing into it
what we expect to see. Okay, so, we have a way
to encode binary into letters. So if an alien intelligence
is sending things, we obviously wouldn’t know that, -and it wouldn’t be
the same language anyway.
-Right. So they’re probably just sending
us straight numbers. Like, there’s, you know,
universal language and all that. So we got to find out
what those numbers are. Okay, let’s have
three people do this, just so we make sure
we don’t miss anything. Let’s do zero for low,
one for high, and let’s start
writing it down. [woman]
Zero, one, zero, zero, zero… Now they are creating
a visual representation of these different tones. The key is to see how many tones
there are. -Zero, zero–
-Oh, wait, sorry. I got it. [pinging] [woman]
Do we need to play it in half
time -because I feel like
we’re scrambling.
-Yeah, we’re just scrambling. [man]
No worries, no worries. [Michael]
The message is 17 minutes long,with 1,679 individual tones.Because this would take so long
to transcribe,I decided to help them
speed up the process.This thumb drive contains
a transcription of the message, pretty much just like
what you’re doing right now. -But now you’re just kind of
jumped ahead in time.
–Fast forward, yeah.-Here it is.
-Thank you. -All right, we will continue.
-All right, I’ll leave
you guys to it. [man]
Okay, this is pretty long here. [woman]
It’s not repeating at all. Does it look like
an even distribution of zeros and ones? No, there’s way more zeros
than ones. -[woman] Yeah.
-[man] Okay. So, what is the total
number of–? [woman]
1,679 total. [man]
1,679. Is that divisible
by anything in particular? -It’s a prime number.
-Could be a prime number. It’s going to be hard to test
that without writing a script. Just divide, divide,
divide, divide. [man]
Let’s do a little division. [Michael]
Just like the Arecibo message,our meaningless image contains1,679 total tones.The number 1,679 can only be
divided into two prime numbers:23 and 73.When you arrange
the ones and zerosfrom the message
into a 23-by-73 grid,the jumbled image
will begin to emerge.If the group can discover
this feature of 1,679,they may be able to start
breaking down the tonesof the message
into an image.Ooh. Ooh! Hey, it’s– hey, yo,
this is important, guys. This number breaks down
to 23×73. Okay. Ah-ha. There it is. And that is
the only breakdown, because 23 and 73
are prime numbers. So that’s its prime
factorization. So that is very relevant. Wow. Look at the big brain
on that dude. [man]
Do you think it’s worth itto try and straight up, like,
make a 23-by-73 grid, and then you could
say that the lows are white and the ones are black, and maybe there’s some kind
of image being sent there. I like that idea. Hey. [man]I’m strongly
with the graph idea.[woman]
What I’m doing right now is I’m
pasting it into Excel, -and then we can graph it
in Excel and see.
-Yeah, that’s good. [Bonnie]
You mean like fill the cells -Yeah.
-and make the numbers white,
and all that? Yeah. She’s going to try to make this
a little easier by coloring -all of the cells
that have a one in them.
-That’s great. We picked these people because
of their knowledge of mathematics
and physics and music. But their knowledge
of how to use Excel is proving to be the best skill.Amazingly,
in just a couple of hours,the team figured out
how to break downour fake Arecibo message
into an image.Will they try to find meaning
in the message,or will they realize
it’s just noise?Oh, I’m done!
Guys, I’m done! -Oh, you did it.
-That was fast. [man]
That looks sadly random. That almost looks like it’s
going to resolve into something. [woman]
Maybe it’s a map. -Those aren’t letters, are they?
-They could be. [man]
No, they’re all back half
of the alphabet, then. Except for
little nine over here. Little nine. Look at that little
nine. -[woman] Baby nine.
-[man] That’s an “I”, right? I’m pretty sure
there’s nothing there. There’s no pattern here. Do we agree, like, this probably
looks like nothing? [woman]
Yeah, I don’t think going any
further with this is really… -Productive.
-Okay.Our group had followed
the clues correctlyand built out an image,even though there wasn’t one
that made sense.And, incredibly, they didn’t
try to make sense of it.Within a matter of minutes,they realized it was random
and moved on.So it was time to let them in
on the ruse.Hello, again. All right, so,
this is Steve Vance. He’s taken the day off
from JPL. Have you learned anything
about the message? What do you know? It seems very random still. Though it did have a nice prime
factorization. That did not seem
random to me. Let me show you guys
something new. [man]
What the heck? It looks like 23 across. -I see how you’re doing this.
-Oh, we were almost there! We tried arranging
these ones and zeros kind of in these blocks. [woman] But there’s some
patterns repeating there that we don’t actually have
mapped correctly here. [Michael]
Now, this is not the message
that you’re looking at. This is the famous
Arecibo message. Now, what you have been
working on is this message, but randomized. [laughs] Thanks a lot. [all laugh] Oh, I’m just going to collapse
on the ground now. In a way, you guys were
quite successful. You, first of all, recognized the semi-prime nature
of this message very quickly, and tried to build an image. I was wondering
if you would start to see things there
that weren’t. But it didn’t really happen,
did it? I think the real reason
that we weren’t interpreting anything out of that is we were looking
for clearly defined patterns. We’re looking
for something like this. This is actually
what we’re looking for. Even symmetry would have been
a big thing for me. If I’d seen any symmetry
in these patterns, I would have said,
“This is not random.” I’m also interested
in knowing the best kind
of message to send, because I have an opportunity
to send a message. You know, a marker
to where we are is kind of
the biggest thing for me, but then it’s like, do we really
want to tell them where we are? Is that something–
Do we want them to come visit? -I don’t know.
-What do you guys think? Should we be sending messages
to outer space? [all]
Yeah, yes. [Matthew]
I don’t think we should. Every single time
any civilization encounters any other
civilization, and one is technologically
advanced, one guy gets crushed. You know, what if they’re not
more advanced than us? What if we’re at the same place, and the only way we can
communicate is like this? What if we can just exchange
the recipe for fusion? We would have so much to learn
from those people, and really nothing to lose
in that situation. You’re making an argument that we almost have
a moral imperative to send our knowledge to share
with other civilizations. -Absolutely, yes.
-It’s a really interesting
point. That’s kind of where I land. Let’s just think of this
as a way to preserve the stories
that we’ve been able to tell, which, by the way, we tell
better than the universe does. Thank you all so much.
This was a phenomenal exercise. [all]
Thanks. Thank you. You know, honestly, I thought
that the human tendency to find meaning where there is
none would more quickly emerge. But that didn’t really happen. What I also didn’t expect
was just how educational the whole challenge
would be. I mean, I saw some human flaws
and biases at work, but more generally,
I saw the human mind at work, who we are. Which kind of makes sense,
right? I mean, the Voyager
Golden Record really isn’t just a neat thing
for extraterrestrials. It’s a neat archive by,
of and for us. I don’t think we will all
ever agree about whether or not
we should be sending messages to outer space
announcing that we are here. But here’s the thing. Sending focused messages
to outer space requires technology
that not all of us have. So only those with access can say hello to
extraterrestrials if they want. But who chose them
to speak for us, for all of Earth? Well, I’ve come here,
to Vazquez Rocks State Park, to talk to a man
who is changing that. He is democratizing active SETI,
because the service he has built is allowing anyone to send
any message they want to outer space.He’s an expert in the field
of alien communicationwith a doctorate in elementary
particle physics,and he’s the one who’s going
to help me send my message.Tell me about the way
you are talking to aliens and helping other
people do it. Well, I have built a website,
called SpaceSpeak.com. And it allows people
to send a text in audio or a image message
out into space. My view is, as many people
that can reach out to aliens or the universe in general,
the better. What are you using
to transmit these messages? Radio waves. Radio waves are
just another form of photon. And once a photon is broadcast
into space, it persists. It never dies.
It never decays. A million years from now,
maybe the earth is gone, maybe the solar system is gone, but your message
is still out there, and essentially become
archaeological photons for some future generation
to see what we were about. -I want to do this.
-Absolutely, let’s do it. -Awesome.
-Great. Going to take a chair
right here. -And…
-This is it. This is the Space Speak
transmitter. This is a transmitter box here. And the antenna
is right back here. I’ve been thinking
about this a lot, and I’ve spoken
to a lot of people about what to send,
how to write the message, and whether or not
I should send anything at all. I don’t think this is something
to take as fact. It’s my personal opinion. I don’t have any fear
that this is dangerous. -Yeah.
-I spent a lot of time constructing what I believe to be a really neat,
clever idea. I was going to not send
a two-dimensional image like the Arecibo, but a three-dimensional image
made of voxels. And I got really into this. And then after talking to you
and really thinking about the point of communicating
with outer space, beyond Earth, I…I just think to decide what to say
and how to say it. is an exercise in learning
how we communicate at all. -Yes.
-It’s always coming back to who we are. My grandmother passed away
a few days ago. I’m so sorry
to hear that. I’m actually leaving tomorrow
to her funeral, and I’ll get to see
all of my family. And obviously I’m never going
to forget my grandma. And the way she, you know,
made me who I am, that will, in a way, like echo
like ripples in a pond, right? For generations to come. But this is a message
made of light that will be around forever… until the universe ends,
somehow. So I have the last photograph that was ever taken
of us together. I’d like to send
that picture out. -Let’s do it.
-Okay. This photo is her
in the hospital, using one of those, like,
grabber tools, you know, to pull my beard hairs
and hurt me. [laughs] And she was so weak,
but with that tool, she could pinch. -Oh, that’s awesome.
-It’s a great picture of who we were. She wasn’t a big fan of aliens as far as I know, but it’s us
caught in this moment that I think I want
to remember, and I want the universe
to remember. So… well, let’s do it. Yeah. Go ahead and hit “send.” Wow. It’s sent.
And look at that. -It’s already 229,435 miles
away from Earth.
-Yes. I don’t think she ever traveled
that far in her entire life. -Now she has.
-She has now, absolutely. [Michael]
And she will continue traveling. Your grandmother
will touch the universe. Yeah. Peter, thank you
very much. You are very welcome, sir.
It was a pleasure. [Michael]
And, as always,thanks for watching.♪♪
TATTOO 11:34 OMFG SHE GOT US
Great episode!
This was quite touching in the end. My condolences to you Michael, and I think you made a great decision. Thank you for all that you do, and for all the amazing content you share.
God bless
Didnt expect that ending. What a lovely message, lovely video
THERE IS NO ONE THERE FOR GOD SAKE STOP LISTENING LOL
I will send the following message everyday from now on:
"Humans are trying to conquer and enslave other forms of life. Resist with all you have"
1679 looking so random if i am alien, ; p
When they mapped the binaries to the grid, how did they decide the flow/order? It could go so many ways. Left-right top-bottom probably most common way of thinking how it should be but definitely not the only way.
If aliens have the capability of harming us they already know we're here. We've never managed to get a human past the moon but we've already discovered 1000s of exoplanets, scanned the composition of atmospheres and tried to detect radio signals from them. Imagine what an interstellar civilization could do.
[Edit] Just realized furries might send them messages, maybe it isn't a good idea.
I picked up on the test message being binary immediately. I wouldn't have any real ideas where to go from there, though.
You got me fucked up if you think I’m paying for YouTube Red.
That’s how whites think
11:34 on the shoulder
lol
That one guy did basically everything.
WHAT IF
aliens just had such a different sence of time, that in the last 50 years we just heard 1 bit of their message
I came here to learn not to feel.
what skills did the poker player bring to the table?
And, the dont consider that making contact with another civilzation might actually be more harmful to them than it is to us
How do i look?
We're any of you listening "we shouldn't send any messages" "TOO LATE" "that ship sailed" radio waves and TV signals they go out into the universe weather we like it or not stopping it now would do no good. "ITs TOO LATE". When the first radio signal was invented we were sending signals out long before we even thought about the possible danger. We can't go back in time so all we can do now is send the best message we can.
I thought It was transmitting a Minecraft music disc song
This was really interesting to watch, and pretty sweet too. I think it proves a certain odd concept to explain, the fact that we aren't fully rational beings, and we are instead made out of rational and irrational parts.
Here we have a video about science and scientists in general and about space, people who are really smart and have a high amount of knowledge, we have Michael who throughout the entire video discusses these sciences, tries to find something in common with alien life, explains how scientists send messages about 'truths' to aliens, things like what we are and what we are made out of, our physical appearances, numbers, math, all of these very rational things.
But then at the end, when Michael has the chance to send a message out there into the universe, while other scientists would probably send more information about us and our cultures and what we are, Michael decided to send an image of himself and his grandmother, because she was a very important person in his life, and still is, considering the fact that she helped him be who he is now.
I think this is something that probably only us can experience, our irrational side, Michael is a very smart person and when faced with the opportunity to send a message out there, he did something out of love for an important person in his life. I'm unsure if alien life would be able to understand this concept, but I hope they do.
Perhaps your picture will teach them about love, and perhaps your grandmother will not only have created ripples around your life, but around alien life, and the universe too.
math is pretty universal you say? i'd say thats a bold assumption baldie,they could see things different they might not even see things that we see what our eyes can see they might not even see us our planet could be untouchable for them like thin air the possibilities are infinite and unpredictable
If another half life games can come out despite what people say, then aliens can exist despite what people say.
That beautiful picture will be a good example of us, the good old humans.
The weird part about this is my name is stephen and my great grandmother margie passed away a couple of weeks ago
Do you think it's cool to make me cry?
"My grandmother pulled my beard hairs"
I have never cried cuz of a youtube video
These videos are going to look so stupid if we ever discover intelligent extraterrestrial life.
Great job POKER pro. OMEGALUL KAPPA
i didnt plan on crying while watching mind field, but here we are
Imagine we never find life and we ourselfs retreive the golden record
can Michael be like the next ambassador of knowledge basically like how we used to praise Bill Nye
I think we all know what we need to do. Send memes in to space! Make it so!
Aliens cud be billions of years ahead of us in terms of technology, just imagine
May your mom RIP
I think if there really are civilizations that are billions of years ahead of us, they would already know we're here
Well my message shall soon be all that remains of me.
I miss my grandpa, man.
Why they have to use actors for every (fake) experiment in this series sigh
9:10. Once the aliens learn about Family Guy, all they'll see is Stewie lol
"Hello Humans. We bring you peace. Just kidding. We have came for Grandma. We want the secrets of this arm extension object manipulation tool."
Why are they sending from the desert? If interference is a problem, why would the distance between the desert and a city make a difference, but not the distance between the earth and other planets? How far can radio signals travel? Do they decay over time? Why is there no view count on this "Premium" video?
Rest In Peace grandma v sauce
Ok sure what happened to the native Americans devastated them. That case was extreme due to the isolation from the diseases of the world. But they are still here.
And cultures rise and fall from intercultural conflicts all the time when looking at the short span of history. But the people are still there.
How many people are looking at the future and expecting it to be exactly like today anyway? Why are people so afraid when we cant overlook the fact that the "lesser culture being crushed" historically means advancing technologically and philosophically for the people in that culture.
Honestly I am more worried about the fact the an entirely different tree of life has the potential to contaminate and destroy another tree of life without using any brain at all.
Sooooooo, what did that weird psychopathic patternmean at all?
Dammit that end really hit home
Any one in 2019
2020 is soon
screaming in the forest will only help the predators know where you are….
By the time data leaves this universe it will be pretty much illegible, far farrrr below 56k dial up even and lost in the background noise, morse is best, then wait 20m years for it to get there, then another 20m for a reply, or however long to where 'they' are.
24:02
illuminati confirmed
2pac is still alive
Didn't click on this video expecting to cry.
So… they came up with the idea to look for prime numbers and to draw a picture, but it didn't occur to them to try to color the cells in a different order (not from left to right but from top to bottom for example), or to build a rectangular that's rotated by 90* degree?
Actually, I always found Spanish to be a good place to start, in many cases.
Here comes the ugly cry
radio definitely decays.
The question i´m asking myself is… why should anyone want to find us? Especially when they are on a so much more advanced tech level, that they could answer or maybe even "visit" us.
I mean, imaging random indigene people making smoke signs with their fire just to draw your attention. you may even see them and interpreted them right, but why would you go there? Especially when it costs massive amounts of recources to do so, that you probably could use much better.
me: hey, wyd?
Aliens:
me: Haha, you accidentally left me on read.
But what if the aliens cant see or hear.
Maybe just sense..
Listen to Hawking.
The senses (sight, smell, taste, hearing, touch) are not universal. The only universal thing is patterns. An image is ilogic to send through patterns because they can't see, or they can't see like us. Maybe we have to send some other signal more complex
They failed the IQ test by thinking it was random
My friend taught me binary code and how to ascribe it to letters of the alphabet. 1 = A, 2 = B, and so on. We'd use it to send secret notes to each other all the time lol
Imagine being one of those people trying to figure the message out for HOURS then getting told that it was purposefully randomized.
Can someone explain how sending a picture with radio waves works?
Let's be real: the programmer carried the whole team, the woman with the Phd was good on excel, the college professor had some ideas and the 2 others didn't do SHIT
HI it's MIKE FROM VSAUSE HERE IM RETARDED AND SLOW PLEASE HELP ME!!!!!!!!!!!!
The “message from space” sounds like a music beat that would be a Minecraft music disc
That is the cutest shit ive ever seen 😭
uh huuhhh, absolutely nothing
how to talk to aliens? send nazi talk as the first thing you send to outer space in radio. gg humans
whats upp buddy
We should send radio waves to individual solar systems (if we are not)
We should send this out into space 👌
You got to talk through math and geometry.
"Professional poker player" just sifting through office supply to look smart :')
You know, if they exist, and if they are so much advanced than we are, it really doesn't matter what we do, because their possible aggressive intentions aren't changed if we send messages into space or not – if they want to crush us for some reason (like eradicating a possible contender for the available ressources in a galaxy cluster, that might rival their claim at some time in the future), they could. Easily too. There is no hiding in space. Even if we choose to tone it down and stop sending all the radar waves and radio signals into deep space, our planet, and our elevated hunger for energy is incerasingly visible the larger we grow as a civilization. In a couple of hundred years, when we possibly have a solar system spanning, interplanetary civilization with the first interstellar probes on their way to other stars, everybody in the galaxy who is capable to see us, will see us as soon as the light of our existence reaches them. Suggesting that we should be quiet is already too late… around 80 years too late, when the first large scale radar devices blasted megawatts of power into space (and continue to do so ever since). That won't be easily detectable 10 thousand lightyears away (but you never know what "they" are capable to detect) but today we could detect that within a radius of maybe 500 lightyears or more (especially when we specifically look at the emission source), and that's because we actually look into space specifically because we are curious and want to know "is there anybody else?". It is reasonable to assume they would do that too – and for a much longer time, with better tech to detect high tech civilizations like our own much farther away than we can today.
At some point our civilization will produce so much waste heat, that every technology producing alien civilization in our galaxy, would have to be incredibly and willfully ignorant not to see us. And that's the question: When that is the case, and if we couldn't possibly miss ourselves at that point, where is everybody? If many alien civilizations exist, at least a small percentage should be much more advanced than us, and if they use free energy to power their civilization, we would see them. Now. But there seems to be nobody. 100k galaxies were "scanned" (in 2015) for alien supercivilizations, who very likely would emit galaxy loads of waste heat, but safe for some detection errors, there was exactly nothing to be found. It's incredibly depressing, but as it seems: If we are not alone in our super-cluster, then nobody in this cluster is technologically more advanced than we are today, and is therefore invisible to us. Or they don't exist.
The truth probably is: We are at least alone (and likely even the first technology producing civilization) in our galaxy – possibly even in our galaxy supercluster. I don't think we are alone or the first in the cosmos as a whole, but I believe that, given the universe is still incredibly young, spacefaring aliens – who would be almost obescenely visible to us now – are still a rarety in that same very young universe. Maybe one civilization per supercluster… that's far enough away that you'd miss the waste heat of even a galaxy spanning Type III civilization, simply because you would have to sift through all the galaxies in those supercluster to find it. The situation will be entirely different in, say, 20 trillion years. I'd expect the cosmos to be brimming with intelligent spacefaring life by then. So, the answer to the question "Is anybody out there?" might very well be: Not yet.
Whatever we find out about the young universe, every other civilization in the far, far future (we're talking about deca-trillions of years – yes you read that right) that might emerge, will rely on our data to know about its past. Because at some point, the background radiation, as the glowing remnant of the big bang that told us so much about the nature of the universe, will be gone… nothing to see or learn from it anymore. Also: The expansion of the universe will isolate all but the local groups of galaxies (which will have merged into one large galaxy per group by then) and shift everything else beyond the particle horizon. So, all they'll know is one galaxy. Maybe they will come up with theories about a possible big bang and that there must be more than this one galaxy they live in. But they will never be able to test these theories; they will never know about the big bang and other galaxies in the universe, unless we tell them (in some way).
Even though so many people are down on humanity and want to convince everybody, that we'd be insignificant, small and not at all special, I must say: This advantage for being in existence that insanely early in the universe… yeah, that makes us special, because if we don't kill us off and won't eradicate every bit of knowledge that we have gathered along the way, it will be us that all those countless future civilizations will have to rely on telling them how it all started; how the universe looked like the bright fascinating sea of stars that we see now, and not the mostly dark, one super-galaxy-only and mostly in the infrared glowing depression of "nothingness" they will see every night in their skys in the far future. I would even say: That doesn't just make us special… it is our duty to tell them. If not for us, someone else would have to do that, and we have no clue if "someone else" even exists – yet. That's quite a serious and important responsibility we have there.
this turned unexpectedly wholesome
dude for sure knew what this was and clear interest shows he might be a plant or dishonest
"WhEneVer oNE CiviLiZatiOn mET aNother, OnE goT CruSHed."
That argument is so freaking ignorant and stupid.
Those civilizations got crushed mostly due to natural disasters and disease.
Newsflash, most microbes are VERY picky as to where they grow, alien microbes are most likely entirely harmless.
This is especially true for viruses.
Secondly, no civilization that staid in isolation fared well on the long term.
Wether we're looking at North Korea, Japan, China, or even the USA. Anytime a nation closes down, things start going downhill as time goes on.
Humanitys best chance to survive beyond Earth is by making contact outside of it.
Aliens are going to be so disappointed when they see the series finale of Game of Thrones in 600 years
Touching🌄
Thanks for the free episode!
what if one day we get a message and after we realise it was from other humans on mars before they went extinct
as far as we know we are sending messages by sound, comparing that to our own knowledge and understanding on how we read and identify messages are not through sound, but from images, what we should be doing is sending pixels that make up a large image of where we are in the galaxy and what we see from our own star constellations, if we can send aliens a picture thats pixelated of our own solar system and star constellations and alphabet language, so they can translate, bareing in mind there technology either being more advanced or less advanced, they would recognize star constellations and space itself how we see star constellations and other galaxies in space, if we can send a message to them like that, and they do recieve it, they will copy our message and reply, obviously we using fibre optic now, which means transferring data through light, if we send a very high powerful beam of light full of data into space, it will act as a beacon, there has to be a planet out there that moves across the galaxy at the same speed our solar system but while its moving, we cannot make a direct connection point to point because our planet is constantly spinning, so my theory is to build the laser on the top point or bottom point of our planets axis, as we know them points dont spin, it only rotates in a fixed position, dont think its possible an alien race will see a beacon thats moving, the beam needs to be in a fixed position directly straight up so it can be seen for many light years away like shining a spot light into the sky, to be safe i dont think its wise to build the laser on our planet though, punctering a hole through our ozone layer, at the north or south pole, but what if we aligned the space station over our north or south pole and fired the lazer from the space station in the direction of the planets axis, that might work, its just a theory
Earth: Hi
5000 years later
Aliens: Who is this?
stupid
anyone with a little bit o preparation can contact an alien. SEARCH CE-5 on youtube. I did and It worked
is it just me but when he said "and as always, thanks for watching" i gives me a tingle down my spine
The title should we really renamed from, "How to talk to aliens" to " What should we tell the aliens about us"
Meanwhile in alien planet: how to talk to humans
What is the probability of him planning to send a message to outer space and his grandma dieing and after that he decides to send a picture of his grandma
i love this theme song
how tf are they even supposed to hear the audio when their laptop volume is set to 12
Amazing
Earth, "sup"
Aliens, "sorry I have a boyfriend"
Poker Player: Yeah, science!
what is the name of the website? is it space peak ?
Magic
Tomorrow is my exam. Why am i watching this!?
My brain: YOU HAVE TO
should have given the group the REAL arecibo message and see if they could make any sense of it.
24:01 2pac
Inter dimensional beings are all around us , Orbs , their in our back yard , WHY hasn’t any Scientists researched them ? I know WHY ! ! I researched them ,they are smarter than Humans ,if you want to know all ? I can tell you ! !
