Searching for Aliens, with Neil deGrasse Tyson
Vložit
- čas přidán 30. 03. 2020
- How much of the galaxy have we actually searched for extraterrestrial life? Neil deGrasse Tyson explores just how little we've looked at with Jill Tarter, astronomer and former director of the SETI Institute. Jill makes an astounding comparison of how much we've searched the galaxy for extraterrestrial life to searching for fish in the ocean that will put things in perspective.
Then, Neil is joined by comic co-host Michael Ian Black and Seth Shostak, senior astronomer at the SETI Institute, to ponder what humanity's role is if we find out we're alone in the universe. Lastly, we answer a couple Cosmic Queries on discovering E.T. signals from life long gone and the process behind sharing signals with the public when we finally receive them.
This segment originally appeared in our 4x Emmy-nominated StarTalk TV show on the National Geographic Channel, and in the StarTalk Radio podcast, The Search for Extraterrestrial Intelligence, with Jill Tarter, on June 2, 2017.

“No proof of existence is not proof of nonexistence.”
THAT IS A VERY SMART WAY OF LOOKING AT IT. HOWEVER WE ARE REAL AND WE ARE SLOWLY BREAKING OUR SILENCE SO THAT YOU DONT ALLOW THE WRONG BEINGS ON YOUR PLANET. NEVERMIND THE NAME REPLYING ACCEPT THAT AN ALIEN HAS SPOKEN TO YOU.
Kayo Gary If any aliens visits us, trust they’ll be the ones who will dictate their interactions. Although my theory is that smarter intelligence will go with peaceful over violence.
Neil deGrasse wont even acknowledge the US Navy official videos and FA18 crews who have witnessed " Out of this world " advanced craft in their words. Keep living in denial Neil - History is leaving you behind Sparky
@@aaronmendezmo0 But also evil doesn't come solely from the search of resources. They may just not value us very much and see us in the way leisure game hunters see their prey.
The absence of evidence isn't the evidence of absence!
I love hearing smart people speak.
Isn't his voice the most reassuring. 🥰
The astrophysicist Morgan Freeman?
Get some intelligent friends and you can hear it all the time.
It gets old, though.
@@jackotears8692 Don't have any.
ooh why only 5 minutes. we need more time for topic like this,please.
IKR
It’s late at night here in England, I can’t sleep, too worried over the recent events....and then I watch Neil, he calms me down with his assured composure, he is such a treasure.
Ausome . He is the best of the best.
"The government is not that high functioning" Mic Drop!
Reminds me of this old blond guy.
Understatement
Or that's what they want you to think of. :)
@@burlak3182 You'd better shut up.
Its not the government idiots. Its the military and anyone who think the military cant keep a secret doesn't know anything
I feel like Neil with comedians is like Batman with his robins. He has many by him but he always needs one😂
Oh

Is anyone else getting Dr. Neil Degrasse Tyson master class ad before his own videos.
No I got a Covid19 ad...#BlowYourNOSE
Squarespace ads 24/7 ... lol
Chris Delagarza I got it watching Pornhub
I did lol
Yeah
After the outbreak, any crowds in a recording give me anxiety.

Neil's face when she said, "one twelve ounce glass". Hahaha. 0:55
It’s also worth noting the sheer distances involved in these searches. We’ve only been around for roughly 100k years. That means that any civilization that might observe us from more than 100k light years away would miss our technological progress.
Well that also indicates something else. The observers from 100k light years away are 100k light years more advanced than us
The ocean analogy was used by Neil in a conference about 6 or 7 years ago! Look at his face when she starts using that analogy! ahahah Plagarism face! ahahah
do you happen to find a source where he said this? I know he said this somewhere but just don't remember where.
He's not the owner
My look in college when I was the first person to do a project in which I made a hand out to assist me. Typed the entire thing from scratch. The rest of the month everyone had an identical hand out just with key facts swapped out.
Professor last day of presentations: Everyone has had the best hand outs this year. :D
he's probably not the first one to make that analogy
For a 5 minute video, this is one of the best startalks.
Your on the right track StarTalk. Enjoyed the format and the length was great. I rarely get to watch the full show but I listen to the Podcast. Getting glimpses of especially your guests fills in those mental gaps that exist when you try to picture someone whom you've only heard and not seen. Makes the community feel smaller which helps with that feeling that we are all in this together so thanks.

The water metaphor was beautiful .
This makes more sense than anything else I’ve ever heard.
I’ve always wanted to work for seti as their representative I love them 💪🏾💯❤️
Where can I watch the full Startalk episode with Jill ?
Juan Green i literally came to the comments trying to find it too
michael black is such a perfect match with startalk shows imo
Glad to see Neil has improved on his interruption problem. 🙏🏿
0:40 eye opening conclusion : The vastness of space deserves that perspective 💫❤️
That was beautiful what I just said.
Now i know where Neil got his "glass of water in the ocean" bit from. She's awesome.
My sister in law worked with Dr. Sagan on the first SETI conference. From this evolved an equation based on the unsubstantiated assumption that life existed in the cosmos. The equation was simply to determine "how many" civilizations existed "out there". Not if any existed at all. My thesis is simple; In all the Cosmos there must be a FIRST intelligence. I believe we are that first intelligence. We are alone.
0:37 is the solution to the Fermi paradox. ie. There is no paradox yet. We just don't have enough data.
Dude it’s Phillip j Stubbs from Ed!
I have the highest respect for Jill Tarter and others involved in the search for intelligent life.
But the very large number of planets is offset by the number of special conditions that existed on the early Earth , and in the four billion years since.. Read "Lucky Planet; Why Earth is Exceptional" by David Waltham and "Rare Earth" by Brownlee. Also, the Fermi paradox is very important.
In a similar vein. Because of the distances, and the time it takes for the light/image to get to us, there could be intelligent life evolving in many of the systems we've already found, but the signs just haven't gotten to us yet. (And may not for decades, or lifetimes to come)
How do I watch the whole show?
Thank you Star 💫 talk for reducing complex science “stuff” to plain English and terms, which I can understand.
I cannot adequately, articulate my thanks.
May the universe keep you all safe.

Here's my thing: think about how our satellites' signals get hard to detect when they pass directly between the sun and the receiving dish. Okay, incidental signals not intended to go interstellar or at least interplanetary distances are quite easily drowned out by the host star. And don't forget that inverse square law that the farther out the smaller the signal to noise ratio. Now I'm not sure of the maths, but there is going to be a point beyond which detecting a signal intended only for the planet from which it was sent becomes nearly impossible.
Now, considering how long we have had radio technology and in that 100+ years only have sent one signal intended for another star to pick up we can assume that the likelihood of ET targeting us specifically is quite low let alone listening in the right direction at the right time. So, we need to listen for ET talking to themselves at interplanetary or, even better, interstellar distances.
If interstellar:
1. They have the equivalent of faster than light radios: we have no idea how those would work and so cannot listen.
2. They have FTL equivalent ships but not FTLE "radio": messages will usually be sent via courier ship and we cannot listen.
3. They don't have a way around light speed limits: communication is hours one way to _years_ and so will be, if done at all, done in infrequent bursts making it hard to impossible to know when and where to listen.
Unless someone out there is actively trying to be found it will be a herculean task to find them.
Neil's face at 0:54 😂
Really nice analogy with the oceans
Worse analogy ever, i would say... you are looking for fishes in a place where we know there are fishes. When we heard this analogy our brain trick us to find that to be true.
Now just imaging this: we are aliens looking for Koalas on the earth and we found A LOT of them in Australia, now we think cause the earth is so big, theres must be Koalas roaming EVERYWHERE. And that's not the case... We are in this Universe Full of things that just happened ONCE. We know that for sure. We are way more probable to be Unique Random event of the Universe and the Evolution.
"We owe it to the universe to keep ourselves going...." Careful, that's how the Borg got started.... :D
😂😂
And they still going strong
Blackrahk no way, the Borg are crippled. Captain Janeway spanked em hard.
@@triscuitfarms Down, but not out!!!!!
"Careful, Icarus..."
This man can now do many things as far as communicating
Nice take analogy, take 1 glass of water out of the ocean and you see there is not fish in it, does it means the ocean contains no fish? That how much we have explored today our universe.
I was laughing on the last statement of Neil. hahaha.
Is this an excerpt from a longer episode?
With JWST we'll be looking at the glass with a magnifier. Then we'll know if there's other life than fish in the galactic ocean.
Remember back to the days when the equivalent of a drop of water was all we -( not me , humanity in general ) had searched? ☺
With covid lingering around for how ever long, Imagine how long it’s gonna take to get JWST in space!!
I'll say it once again and I'll say it again we are brainwashed and trap on this planet we cannot be alone in this vast universe there's millions of other worlds out there and to me that's pretty amazing
There is a message in the light FROM THE ATHATHALU. A light bulb is just light to you however there is information in the light wave frequency.
Where can I find the full video?
I think the argument about the mail was phrased wrong. It would be better to point out that the letter tells us someone *did* exist and that, alone, would be amazingly exciting news. Furthermore, the fact that someone did exist suggests the fact that others can and probably do exist as well. Once you prove we're not alone, you open the possibility that we are 1 of many.
I thought his suggestion that the message might be '100 years old' kind of missed the point of people's arguments, however. If our nearest neighbor likely to produce life is 20k lightyears from us, meaning light from its sun takes that long to reach us, then how long would it take a communication signal to reach us, or even become detectable?
Radio waves travel at the speed of light.
@@kolbymorgan7802 So, 20k years, then?
@@jackotears8692 yes sir!
@@jackotears8692 actually it would take longer than 20 thousands years because you would have to account for the stretching of space between them and us
So it may add a couple years to that 20,000
0:55 Niel's trying to hard to not look blown away.
Joey Godsey lol he has publicly given this exact same example 10 years ago, look up the talk with Richard Dawkins (near the end at the q&a). And yes, I have watched way too many NDGT videos
I think its probably closer to one water molecule than 1 glass.
Seth is great
What do you think of those newly released videos?
I heard this glass scooping from Neil first, years ago
Believe it or not, 2600 years ago, Buddha did mention the extraterrestrial in other 3 planets beside earth. These were written later in the Tripitaka.
If you scoop a glass of water from the ocean aren’t you likely to find microorganisms?
Didn't Neil make this exact comparison a long time ago... but used whales instead of fish?
It originally came from Carl Sagan.
We are not alone. We are also not ready.
How much longer Neil how much longer until you get it. We have emailed you we have tried all subtle ways. This is not a joke
Neil is just getting us ready for the aliens they have recently discovered!
♫♪Ludwig van Beethoven♪♫ and that’s where covid came from😂😂
you can tell he loved that analogy
This one man has seen the technology we have we do not care for religion however by making contact with this man we have shown something beyond our imagining
1:00
you don't need to look through miniscule ounces of night sky (in this case water) to be able to find other sentient intelligent life at least as advanced or more so than us....
Of course there's life on every single planet orbiting the Sun. While all life isn't humanoid they all have a unique level of intelligence and communication. The continous rally to keep earthly humans separated and at disadvantage continues to restrict and delay required advancement this galaxy is demanding.
Appreciate the differences of others regardless.
I know that there is life out there because there are plenty of earth like planets in the universe that we have discovered, so there is no way that there isn’t any other life.
WOW! Fantastic! Thank you!
Well explained.
Why even spend the energy to upload a 5 min video.
Space Man I enjoyed it
Shorts act as commercials. They can use the most interesting part of a larger show and attract more viewers.
I scooped a glass of ocean and found a billion microorganisms .
SIR I WANT TO ASK ONE QUESTION :- 1. WHILE LOOKING IS THE SKY FROM THE GROUND IN THE DAY TIME SKY SEEMS BLUE BUT WHILE OBSERVING EARTH FROM SPACE WHY DON'T ME SEE A BLUE COVER AROUND THE EARTH AND 2. WHY THE LIGHT COMMING FROM THE OTHER STARS ARE NOT SCATTERING IN THE NIGHT TIME....... ATLEAST SOMETHING MUST HAPPEN??????
Prateek Dhariwal please don’t shout🤫
Prateek Dhariwal please don’t shout🤫
@@misterexponential who r uh by the way
Why isn't this an hour long?
Imagine if aliens became super advanced not by conscious integrations in technology but instead many MANY years of enduring the 4 factors of evolution. Or is consciousness a tool of the latter??
Why haven't we found a way to build and power gundam with nuclear energy and send them on intergalactic quest. They wouldn't be used for war but they could be a practical solution to space exploration and beyond....
Hey Neil.☺️
Neil time does behave the way you think in the outside the universe. You can phase in and out. You can cheat death that way because time behaves differently.
Causing our own extinction would be the most irresponsible and wasteful action that can ever be done. There are planets that are made of gold and rain diamonds, but as per our knowledge, we are the universe's rarest opportunity and are the only way for the universe to have meaning.
There is a message in light
no full interview???
So trying to find life in the galaxy is like trying to find a coin in the ocean.
So the original speaker of “Claiming there is no other life in the universe is like scooping up some water, looking at the cup and claiming there are no whales in the ocean.” is actually Jill??? Or she just quoted someone else? If so then from who?
The Wave
It will be just a big silence out there,if we destroy ourselves and nobody s out there...
Welcome to the government's list Neil
Lol fr
Are we detectable in the universe?
Please interview Jill Tarter about how likely it is that we have been detected or will be from signals we have already sent by another life form.
I don't think the fish in a glass of water analogy works too well because if you stare at a small section of a body of water with fish in it you are eventually going to see a fish pass through there. We haven't observed any aliens in our visible area, or evidence of the aliens having ever been there; no ripples in the water. Not to disagree with the overarching point, but I don't like the analogy.
What difference does it make if are alone or not? We cannot even live with other humans
Isn't the issue that we haven't seen any Dyson Spheres or any Stellar Megastructure either?
the thing is... we not even start. not even a beginning
I think Neil is trying to give us inverse message in April 1st
Neil looks like he’s in much better shape
Now this z eye opening, they exist!
Vast distances and vast places to search make the search fun but not very profitable.Dont hold your breath.
If there was another us many light years away , how likely are we able to detect another us
How long does it take to produce enough organic material ( through supernovas) in order to create an planet which can produce/sustain life
I don't know the answer, but I will say that our solar system is believed to be an 8th or 9th generation of star cycles due to the number of naturally occurring elements we find.
Millions
Millions what?
@@JasonWW2000 of years
Well planets are created when nova blow up or should I say in then up ...they send element enriched dust and gasses into the atmosphere. Over long periods of time the ball of dust and dirt begins to accret more material...but for it to be a planet it has to be big enough to take on the shape of a sphere ..then the differentiation process takes place due to the process of accretion (elements combine) the planet gets hotter. When the planet gets hotter it makes heavy elements sink into the ground . Materials such as metal, cobalt, nickel, uranium etc. As this happens the lighter elements such as , hydrogen, carbon,silicate etc start to rise. then life can maybe perhaps be terraform able. ...so yeah its gonna be millions of years. It also depends on the planets magnetic field and gravity.
Thank you Dr. Tyson :)
Niel bless your heart!
"If The Universe has no other consciousness in it?" The fabric of The Universe is consciousness.
Perfect!
If we did find radio messages , them messages could be obsolete technology after centuries of traveling through space , they would have progressed onto new forms of communication , so we could actually be playing catchup so to speak
his face when she said 1 12oz glass 😂
Watch The Phenomenon!!!
I'm in love with science
How long before you realize Neil
Will you tell brush him off or will you take a real look at these messages and see.
One man figured it all out neil
Yes Neil there are many aliens in the universe
I remmember hearing Niel giving the very same example with the glass of water before. So funny to see how someone is telling him the same thing and how he pretends he hears it for the first time.
