Neil deGrasse Tyson: Where Are the Aliens?
HTML-код
- Опубликовано: 3 мар 2015
- If there is alien life in the galaxy, where are they? Have they already visited Earth? In this video from Business Insider and StarTalk Radio, astrophysicist Neil deGrasse Tyson speculates on what might happen if aliens do visit Earth, and what they might think of us, our scientific achievements and our early adventures in space. Neil also discusses what Stephen Hawking’s fear of aliens really says about how we have treated less advanced civilizations in the past.

*Where are the aliens? Have they already visited Earth?*
Neil deGrasse Tyson speculates in this video from Business Insider & StarTalk Radio: ruclips.net/video/O7ctfSIzeFI/видео.html
I agree, we aren't the smartest of species to want to strike up a conversation with. We as well act hostile towards each other, why would they get involved a mess like that when they could find a species that has a brighter future?
In the Pentagon?
What if aliens aren't interested in gravity wells of planets? Everything they need is in the ort cloud...
StarTalk Radio Reminds me of the scifi story "Road Side Picnic". Aliens came to Earth and made a mess where they parked and had a picnic, so to speak; they didn't care one bit that humans were around.
If we consider so-called Phoenix lights UFO sightings (1997) and Belgian Wave UFO sightings (1989-90) just *seriously*, we should admit, that some kind of extraterrestrial, alien, whatever, intelligence has *_already_* demonstrated to us its presence/existence. Those were immense craft with unimaginable aeronautic capabilities. They were neither hallucinations, nor mirages, nor natural phenomena. We should remember such phenomena when we ask where the aliens are. The answer may be that they are already here (at least occasionally, from time to time, maybe).
I'm so glad I watched "Everything Wrong With Interstellar" and that it led me to subscribe to StarTalk Radio. I enjoy getting my mind blown by things like this!
Not a smart person here, but I do like listening to smart people.
+MercuryAlphaInc Just watched it too lol
+MercuryAlphaInc Same thing! I had no clue this channel existed and now I am going throught these vids like a child that goes through a free candy shop.
+MercuryAlphaInc me too :D
+MercuryAlphaInc there's no such thing as a smart person we are all ignorant
+MwaelG okay...? How's that?
I actually try to not step on the worm if I notice it. :P
Same here
The God Emperor I try not to as well, but only because I don't want worm guts on my shoe.
don't they clean up the dirt
I step over the worm not on it, and I do wonder what they are think, I even wonder what dogs are thinking. I even wonder what monkeys are thinking, what cows are thinking. horses etc. thats how we as humans learn about others.
The funny thing is, I *do* wonder what the worm is thinking about. And if I see it wriggling on the sidewalk I pick it up and put it in the nearest grass to help it out a bit.
How he said "Forget it!" was just hilarious.
We really need more people like Niel deGrasse Tyson to get much more of the younger generation interested in this stuff.
Maybe aliens just think humans are d-bags. The most popular humans usually are.
I love it when Neil talks about Alien civilizations. I feel like he doesn't take an anthropocentric take on things and he comes up with very fascinating and valid points.
You just wished you where not racist but it's isn't working trust me it's the goth look that shines through
Fake fake
@@mauricehammond2062 no u
Neil's just SLAYING everyone. It has me in tears. I love it.
The aliens land at ComiCon.... and nobody notices ;P
+BlackEpyon Thats a b-movie comedy right there
Made me think of the movie Paul 😭💀
I'm happy he mentioned what hawking feels on this. I agree with tyson on this, but I would like there to be more discourse on the matter, rather than simply presenting his thoughts.
Equally important though is the factor of time. Earth & humanity, in the scheme of time of the universe, have existed only for a miniscule amount of time.. a blink of an eye, if that. The universe and time are so vast that countless number of advanced civilizations across the universe could have lived, explored space, then died off for any number of reasons. Space & time are so vast that the probability that two space faring civilizations existing at the exact same moment in time, and encountering one another, are so unfathomably small that the probability humans will ever encounter advanced life during our species existence is likely laughably poor. Even if humans somehow survived another 1 million years, in the vastness of the universe & time, we still likely wouldnt encounter advanced space faring life.
Hathur You already said what i came here to say : ) Universe is not only vast in space, it's equally vast in time, and we are extremely self destructive, greedy culture. Will our evolution bring new type of human being and new type of sustainable culture? Remains to be seen. Not by us, our time is so short : )
This assumes that other civilization have died off. What if they all started at different times but never died off? That would raise the odds a bit.
Also we don't yet know that we will die off either. It certainly seems that way, but there is not hard proof on this. There are many things from the past that seemed impossible and we take them for granted today. Maybe humans will make it to eternity completely against our expectations.
+SergeofBIBEK The Sun won't shine forever... we WILL die off. It's merely a question of when.
Bradley Kell Indeed. The sun won't shine forever. But I don't think that will kill us off. Scientists know around how long the Sun will shine. I don't have the numbers but it's so far off that other things would kill us first.
Given the insane amount of time the sun will last... and how far we've come in just a few thousand years.... heck even that last few HUNDRED years have been leaps and bounds in technology... I think the Sun burning out isn't going to kill us off.
SergeofBIBEK But it IS an End Game. So say we beat the odds against all those things that SHOULD kill us before the Sun dying does... the Sun is STILL going to die.
So we got to get REAL good at Galaxy Hopping to find Earths to live on that have Suns to sustain them. And eventually... that Sun will also die.
I mean, on the law of Averages, you are going to run into a point where you don't have a proper place to move Humanity to, because the right Planet/Sun combination doesn't exist... and then it's lights out for everyone.
Now, Colonizing on Ships is a thought... but then it's that battle of resources and space/confinement all over again... not to mention getting blasted by space particles/junk/random asteroid type stuff.
Much like in an Individual's Life, Humans are NOT going to last forever. The idea is to accomplish the most we can WHILE we can. Because the curtain IS going to fall.
It's the circle of life, my man. We are going to exit, stage left... and something else will rise over our bones.
i swear i like this guy. very down to earth yet very explicit in his explanations.
I would love to have like 30 minutes in Neils office just so i can route and play with all the things on his desk
shoulda made this like 45 minutes long! i could sit here all day watching
To quote Monty Python: "So remember, when you're feeling very small and insecure, how amazingly unlikely is your birth - and pray that there's intelligent life somewhere up in space, 'cause there's bugger all down here on Earth."
Is there a possibility of any Life forms having DNA that can spin clockwise and counter clockwise too?
This is one of my favorite videos. Great insight
I hope your being sarcastic
Point at 1:55 is gold.
I want to know why Tyson appreciates that Starry Nights painting.
Thank you Mr. Tyson. I personally agree with the idea that any species that is obviously way more advanced would not make the journey here just to start a fight. I do also believe u are right about comic-con. Keep up the good work.
+redexoudos I was just thinking, if what we see in the night sky is the past, ie light that is so old that what WE see right now , may not be what is happening at the stars/ constelations right now. Could it be that we dont see anything 'alien like' because as we look further out we see light that is much much older and nothing would have been built by alien civilisations yet. thus they could be there right now but we just cant see them becuase of how long the light takes to reach us. Same goes for communication, it would take ages to send signals via light across these vast distances.
Many of them are all around us already in different dimensions; sweeping in and out of this one.
"Where is the nearest star system? FORGET IT!"
Best line EVER
Ha ha ho very funy
I think a race of beings maybe thousands or millions of years older than us would observe only , how they would get here from many light years away, bending time and space from one point to another when they enter one end they immediately would come out at there destination and possibly resulting in a massive sonic boom, this is just my silly thoughts.
Layin' the smack on Hawking...I love it!
I don't think he is laying the smack on Hawking. Hawking has a valid point. If life elsewhere in the universe started like it did on this planet, then it would stand to reason that they would share many characteristics with humanity here. Given that line of thinking, we don't have a good track record at all in regards to how we treat other, less technilogically advanced civilizations. Not only that, the intelligence gap between us and the other sentient beings on this planet is pretty large. We share 98% of our DNA with chimpanzees. Think about that for a second. If an advanced alien civilization had been allowed a few more 100 thousand years to evolve ahead of us, and was only a 2% difference, them trying to communicate with us would be akin to us trying to communicate with monkey's. Though they might see a sliver of intelligence within us, if they're anything like we are, and their intentions weren't altruistic, they could crush us without ever batting an eye. It's a scary thought.
Nick Barden Hawking does have a valid point, but you have to take into consideration what kind of species will make contact. What do they need? How does their civilization function? I would say most of what we may encounter would be friendly. You dont communicate over thousands of light years just to immediately plan on war. Imagine the renaissance our civilization would experience over established contact with another species. But, a small percentage of races may not necessarily be malevolent but simply indifferent. Our planet has resources on a ridiculous scale, and they need it. We either assimilate or get harvested. I imagine this would be the case with an AI scenario. Most of our challenges are, in my opinion, philosophical in nature. We have a pretty sweet and unique spot in the galaxy and we've got to be entitled what with religion and all (science too more than people think). We think we are special, and maybe we are, but we need to realize how importantly insignificant we are. We talk about sailing the black, but focus our resources on selfish endeavors at the expense of each other. According to the Kardashev Scale our time is now to either destroy ourselves or level up. Finding another race, good or bad, might be our saving grace.
*****
What kind of species will make contact? Well for starters, the one that outcompeted every other species on their planet to evolve to a level where they could develop technology. Then the civilization within that species which survived whatever wars they had. Then that species also had to survive contact with any other alien species they encountered before us. So yes, any species which we encounter is likely to have at least have had a good deal of experience with wars in the past at some point. And if they are capable of reaching us at all, they're certainly far more advanced than we are. Maybe we'll be lucky enough that by the time they reach us, they'll decide we have nothing they need badly enough to take. And maybe they'll decide we're still too primitive to be a threat. And maybe they'll decide not to kill us now in self-defense before we DO become a threat to them. But I certainly wouldn't bet on it.
SkyrimHod
Space is so unimaginable vast, even if an alien civilization was looking for other life, it would be a total shot in the dark (literally). We'd be a speck of sand on a beach, with countless other specs of sand without life on them. If any aliens were able to traverse such incredible distances to find us (and in which case, it would be that they stumbled upon us, rather than actually look for us), I don't think they'd be very interested in communicating with us. We are the worm to their foot, in a sense.
Nick Barden
I think any civilization that advanced would've altered their genome to remove aggression and other similar genes. In fact, that might be a necessity to survival at a certain point.
Why even assume aliens need space ships, or even desire the things we want: food, sex, land (shelter), etc. This alone shows a vast oversight of the majesty of evolutionary creation.
Talking smack to Hawking... I like it.
I could listen to Neil deGrasse Tyson all day.
My fav part of this clip is Neil's half assed attempt to spin the globe on his finger like a basketball. Priceless.
I don't agree with all human stepping on worms because I do not step on worms other than that Neil Degross Tyson always make sense
I like the idea of aliens who can shape shift are amongst us.
You're awesome Mr. Tyson.
This..........Is Star-talkkkkkkkkkkkkkkkk.
A British TV Show, "My Hero", did the idea of that aliens go to sci-fi conventions because they blend in there, :)
Once we achieve better tech to travel Aliens will show up and be like: "Eh, welcome to the club!"
Neil is a hero of science..
It's possible the reason we haven't seen aliens is because they know we'd all laugh our heads off seeing them first time.
I like the idea that Fermi Paradox gives. Multiple scenarios where one of them suggests that we might be the first superior species. Other theory is just what deGrasse said.
If you want to read more about this: waitbutwhy.com/2014/05/fermi-paradox.html
I don't think we should ignore the fermi paradox because aliens would find us boring, because if there is one intelligent civilisation out there, then there is bound to be hundreds more, and surely some of those would be happy to discover life of any level of intelligence.
"the nearest star system?......FORGET IT!" hahaha
On the scale he is using Alpha Centari, the nearest star to us, would be 55,000 miles away.
Just a random thought. If universe started everywhere at the same. Wouldn't aliens be on the same level of intelligence as we? Maybe thats why they didn't visit us because they cant
I subbed and I'm addicted. IFLscience sent me here!
Thank you! Finally someone gets it. Just because we act like the parochial little predators we are, doesn't mean every life form in the universe does.
I've always thought that if alien's traveled across the galaxy to get here. DON'T PISS THEM OFF!! 🙂
Even if they didn't think there was "intelligent" life on this planet, there IS life on this planet.
Given how rare that "seems" to be in the universe, I imagine if aliens did come by our planet, they would take interest on it simply because of that alone, not because they think they could teach us anything.
I imagine they would want to study the planet, and possibly take its resources.
If they had the technology to get to our planet there would absolutely be no reason to take our resources.
What resources? What is so valuable that accelerating/decelerating anything with mass is worth the effort?
Shawn Tannehill
Seeing as how we have no resources worth taking.
Water? tons of it in comets.
Precious metals? Tons of it floating around free for the taking.
The only thing that's of any uniqueness on the earth is Oil, so let's just hope we use it all up before earth becomes an intergalactic middle east.
It's a lot more likely that if aliens were capable of visiting our planet, that we wouldn't be the first "aliens" they've encountered, and that we'd be relatively uninteresting.
***** Oil is unique but again if they have the technology to travel interstellar what the hell would they need oil for. We use oil because we haven't figured out a better source of energy.
Everybody seems to assume that aliens want to:
a) travel
b) explore new things
c) find life
d) find intelligence
Pretty sure there are aliens out there but i doubt they want to "explore" or "communicate".
What is life? Maybe we're really limited in our definition of life.
I admit it. I'm hiding the aliens. They're in my basement.
What if intelligent life is common, but if you look at the whole timeline of the universe, civilizations come and go too fast for them to meet each other in time...
We'll be contacted by the United Federation of Planets just as soon as we achieve warp capabilities.
Wouldn't an equally appropriate question be "When are the aliens?"
tweekyseagull Aaah, yes.
Dr. Tyson is my hero.
They did a fly by, saw we were worms that could drive cars and said Ight imma head out
There is one much bigger reason; in our future it will be much easier and cheaper to create virtual universes with "intelligent life" than to trek the stars. Imagine being able to interject yourself into a world, like a prophet, and how much more exciting that would be than traveling all the way across the galaxy to see just one other world. One big bang simulation that takes just a few weeks to generate, could create enough entertainment and information for a life time. Take a look at the virtual universes we are already creating, which are already more detailed than images of our own universe. Then imagine when we start to code in some evolving and intelligent life. If we can witness the birth of a universe from beginning to end, then space travel to our galactic neighbors just seems like wasted resources and time.
Now, I could imagine some sort of long distance communication and visualizations for interstellar life... crop circles and orbs of lights witnessed by pilots could be the real deal. It's more likely that our creators of our universe are walking among us than interstellar aliens.
anyone notice the face in the clouds by Hawaii at 1:46?
no
1:36 is hilarious.
this guy is perhaps the coolest guy on earth
And your probably the most idiotic
We have not even observed outside our cosmic back garden with any detail, so we would be very stupid to assume other life is not out there
When humans come upon a new species, we first try to find out if it is dangerous. Then we want to know how vulnerable it is to us. Then we want to know whether or not it tastes good.
We'd better hope that the aliens aren't hungry.
Me: i want more salary.
Boss: 2:42
Sometimes I wonder what those ants are thinking... won't there be an alien astrophysicist like me?🤔
Eh. Description made me think he'd be talking about life-supporting exo-planet hopefuls. Even Europa would have been okay. Kinda disappointed.
Neil still did well, but I gotta say, I find the Business Insider tie-in pretty weird. Are they paying him and StarTalk to be associated with them, so they can use StarTalk content?
Ultimately, I think it's about "Consciousness." I think what most of us fail to realize is that everything, from what we think to what our senses experience...is human consciousness. From our perspective, Matter is what consciousness "looks like" (or feels like, etc.). Consciousness is "what it's like" to be matter (see Panpsychism). Furthermore, I suspect there exists much, much more than human consciousness...there may be a huge variety of consciousness all around us that we can't detect. Some forms may be quite elementary from our perspective...but some may be way more complex.
Like grains of sand, each having its own unique geometry, human consciousness is but one type of consciousness amongst billions...but because of our uniqueness, we appear to be alone.
It's time for the human race to begin looking at our reality from a different perspective. We are NOT the gold standard by which all other types of intelligence must be judged...we are but one type.
Up to now, we have peered into the cosmos in search of intelligent alien life...but in reality, we've been looking for ourselves.
Neil deGrasse Tyson ... smartest man alive !
It's like the mall of America they take tours to earth. And watch us like we go to the zoo to watch.
Hey Neil DeGrasse, my question is this. So if I would throw a ball of a train moving at 60 mph, the train would move away from the ball at 60 mph plus how fast i threw it. Our first probe was Explorer 1. My question is why isn't it moving away from us faster considering our galaxy is moving at 515,000 miles per hour? And if it is because of gravity, then when it leaves our galaxy will it move away from us faster? Because my thinking is, it should be moving at how fast it first was traveling plus how fast our galaxy is.
It is because its locked into the 'gravitational' forces of the combined galaxy and its mass. Technically the probe is moving that fast, however we perceive that its not because all of the mass around it (the galaxy) is still nearby. If the probe was really far away from the galaxy, it would move at a different speed.
Neil, as much as I love you (I really do) don't belittle Felix Baumgartner's jump. I'd like to see you try it.
oldie but a gooodie
Don't be afraid.
aliens would have to need resources from our solar system in particular.
I recorded a UFO buzzing the tail of a commercial airplane in OKC, on March 26, 2013. I cant post the link.
I remember this episode of the tv show C.S.I. Gil Grissom was telling this alien cultist girl “If there is intelligent life out there in the universe, they are intelligent enough to stay FAR away from us.
I never agree with the notion that Aliens would see living organisms on earth and think "oh, there's nothing intelligent here, let's move on" as we would with a worm or an ant; an intergalactic species would of had to have seen so many more worlds with life just as ours to reach a state of looking at us as common. Beyond that even if we were, we'd at least be a statistic worth adding to a graph. Maybe a graph of "average time taken to reach technological milestones," "number of isolated/global conflicts vs. time," or even "similarities and differences between interplanetary cultural trends."
That last one was probably why they were at NYCC.
i think if aliens are advanced enough to visit earth, they'd be advanced enough to recognize that although primitive to their standards, we are intelligent and would value the scientific gain alone from observing life on a different planet
When they land, we'll all know within 2 minutes.
new subscriber 🍿
Why would I step on a worm? They recycle the soil in the environment so stepping on it would halt progress. I personally toss the worm in the grass and say "Get back to work!"
I think Hawking has a point. Say aliens needed our planet for whatever reason they might be sickened by what we're doing to it and justify using it for a better purpose. Like when we destroy beaver dams. The beavers think its perfect but we destroy it because it's hurting us. Also aliens surely evolved from primitive species and like us still have primitive ways of dealing with things. Id venture to say if we ever meet an alien civilization they may not look like us but we'd have a lot in common.
What exactly is a what does the nature of B,E.C. (Bose-Einstein-Condensate) tell us about the nature of the universe? Is it at al possible that we are the result of some sort of interaction of matter below 0 K?
Humans have the capability to increase their intelligence I think this is crucial.(through eugenics)
+Display name congrats in being a dead dealer.
"That's where he jumped. Right there. You see that? No, you can't see it because it's a sixteenth of an inch!!"
Ultimate troll right there lol
+Says The Big Bear Neil DeSass Tyson.
nice office
His dismissal of Hawkings concerns as being predicated on a human perspective of what humans do to each other is itself predicated on the belief that the only invasive and aggressive species in nature we've observed is humans, which is patently false.
I actualy was thinking about what the worm things :(
Oh Neil you are the best!
On this scale (with his globe) , the nearest star system would be 556,293 miles away
So twice as far as the Moon is from us
Yeah! Take that, Stephen Hawking!
Q: Where are the aliens?
A: They got NASA funding.
Neil indirectly says Hawking’s thoughts are anthropocentric. In other words he is saying Hawking is a little ant who cannot see beyond his ant hill.
One question about aliens please....
if there is a planet with aliens orbiting a star that moving through space-time half a speed of light, if the creatures there live 100 earth years, one day they have come to earth will they be dead in a year or shorter? so types of aliens that we should beware are the aliens that lives in the planet that orbit a star moving through space-time much much slower than earth coz they would live for thousands year if they really came to earth right? ^ ^
Atipat from Thailand
More advanced societies seem to have a tendency towards more humane ethical treatment of animals. No reason to be certain that alien life forms may treat humans less ethically rather than more. Hawking's extrapolation is not necessarily true either. Not to say that they still wouldn't be hostile.
Yep, nailed it.
We will meet alien species when we achive type 1 status, I hope.
Most likely type 2 or 3 cause thats when we have the capability of traveling great distances.
***** I mean as in that they will contact us when we reach that level, because we won't be as primitive & destructive, that if we ever get there.
Antonio Martin in that case than yes we may get contact at that point of time.
Driving around the block hahahaha Mr Tyson you're a legend!
While I do like the concept that aliens are so intellectually different from us that we'd be unrecognizable to each other (like as a sci-fi concept), I think this is fairly unlikely. I think the comparison to a worm is flawed, it's based on the assumption that a worm has conscious thoughts, whiles its more likely that the worm is operating more on an evolutionary pre-programmed instinct like a evolutionary computer program and doesn't really HAVE thoughts like we think of. Some people might think this is an arrogant view point, but it's really just the best guess based on observation and experimentation we call science. To think an alien species would be SO much more advanced that they'd be unable to recognize OUR intelligence is kind of saying the aliens are so smart they're dumb. I do think it's possible that thoughts and emotions are so incredibly different that we have difficulty understanding each other, but I think it'd be obvious to them that we have A level of intelligence just as we recognize some level of intelligence in animals. I suppose it's possible they wouldn't significantly value our level of intelligence, but assuming morality and intelligence have some kind of link (which I think they do, preservation of a species is easier if they aren't slaughtering each other) I find it more likely that they wouldn't "step on us" having developed a similar respect for life. (For those of you arguing we DON'T respect life, stop being stupid. YOU probably respect life and to then say PEOPLE don't respect life is probably just you trying to make yourself feel superior and special...like everyone says they're a better than average driver... but they're not.)
So MY explanation as to why we don't see other species. Intelligent life IS rare. Most interstellar intelligent life doesn't feel the need to propagate it's self at an exponential rate having already ensured it's survival through multiple colonies. Most interstellar life is operating technologies beyond our understanding and detection. Think about it, they're able to travel to other stars, but they're wasting energy broadcasting everything in every direction? Directional antennas are becoming common place HERE, I'm sure their tech will be better. And finally, I think its much more likely that they have a prime directive of some sort, and morality being correlated to intelligence, they just don't have members of their species that are likely to violate their laws for no good reason.
Aliens probably do not even need to physically travel to another star , maybe they travel through their thoughts . Maybe they have inbuilt radio systems that allows them to communicate with each other at vast distances without a need of all this hardware that humans build in order to communicate. In fact we have creatures that can communicate or able to locate each other in a way that is unimaginable for humans here on earth without technology. The challenge with us humans is that when we ask ourselves where are the Aliens but we are not really looking for anything Alien to how we understand life in this planet, we are actually looking for other humans that evolved in outer space .Yes they are Aliens because they are not from here but I don't think we will ever find them not coz they do not exist but we have numerous limitations to achieve that.
I am impressed
Where are they? You don't know, do you? Ever consider aliens invisible to you?
The most obvious sign of intelligent life in the universe is they HAVEN'T called.
"where is the nearest star system?...FORGET IT!!"
Earth is a 1 star hotel.
This guy is awesome!
Hawking just got schooled son. GET REKT!!!!!!!!!!
ankurama I'm just joking.
ankurama Did you need to tell yourself that?
Vizulize MPD bro....
ankurama I laughed.
