Dr. Tyson is so smart and a great communicator of science!

“Intelligence is the perfect thing to have to render yourself extinct” We know we’re trying!

I watched both Brian Cox, who's someone I discovered only more recently, and Neil deGrasse Tyson on *_Solving The Fermi Paradox_* and I must say... while Cox is great at giving answers and explanations in a lucid way that makes everything he says make sense, Tyson is great bringing out questions, like constantly firing up the human curiosity and that's the thing that drives me crazy about what science tries to solve. I feel Neil de Grasse Tyson embodies the spirit of Science, he has the unmatchable capacity of making me emotional about Science in a way I've never been before despite my untold and unspoken dreams about space, astronomy and other forms of life across the universe. Neil deGrasse Tyson has blown into the sleeping fire under the dust and turned that passion of mine on fire again. This short video itself is another one of the many examples of how much emotional I can be listening what he has to say. I find that a gift and priceless. Thanks Professor deGrasse Tyson, thank you!

Those living in the Americas thought they were alone on earth until the first Europeans crossed the ocean. Thousands of years divided the two areas of existence and we only needed to span a few thousand miles to break the isolation. Why would we not think a similar divide exists at a cosmic level multiplied exponentially.

If I was as smart as Neil, I'd go nuts. 90% of the time he probably feels like he's surrounded by 3rd graders who can't comprehend him. Got to be depressing sometimes.

'Intelligence is NOWHERE in the fossil record; it is not necessary to SURVIVAL.' My goodness, Neil has some gems and doesn't even do it intentionally 😂

Why do we assume other life forms would have evolved faster than us? Maybe we’re the first. And maybe a million others are evolving in parallel with us.

Considering how psychotic we act even toward our species they probably have enough sense to stay the hell away.

As Dr Malcolm says, “Life finds a way”

The universe is infinite and has been around at least 14.8 billion years. We as a human species have been arpund 200,000 years at best. I am sure different forms of life, intelligent and not, have come and gone trillions of times throughout the cosmos, but the chances of intelligent forms existing at the same time and being technologically capable of interstellar travel are absolutely miniscule.

Simple answer: distances are too great.

I go with the rare Earth hypothesis. In particular I believe that our freakishly large moon, and how that moon was formed is why we have intelligent life here, but not anywhere near by in time and space. Specifically, late in the formation of the Earth a planet the size of Mars slammed into the Earth at an angle. This did several things - one, it gave us a larger than normal iron core, because now we have the iron core of two planets, not one. Two, it increased the spin of that iron core. Combine one and two and you end up with a stronger and longer lasting magnetic field then we should have for a planet our size. A magnetic field that protects us from the solar wind. A weak magnetic field is why Mars has such a thin atmosphere and high surface radiation. Third, the lighter material got blown up into orbit where it formed into the moon. Our moon is freakishly large for the size of our planet. This has several effects, it increases the size of our tides, mixing up those chemicals of life so well, and often. It stabilizes our rotation so that the Earth doesn't wobble, which stabilizes our climate. Our freakishly large moon also provides an asteroid deflector. An imperfect one to be sure, but on that increases the time between extinction level events. Add all of that up and we have a planet that allows a long enough period of time for intelligent life to evolve, something that seems unlikely on other planets.

Why do we always forget time as a dimension when discussing alien life? Maybe other intelligent civilizations have came and went in the 14 billion year history of the universe or maybe its developing on a slower rate somewhere else in the universe? We've existed for a blink of an eye on the cosmic scale and we're already fearing our extinction. Maybe universe just gives small windows of opportunity for life to thrive and smarter the life gets the harder it is for them to survive for long period of time.

NDT saying “receiving” information at a distance” was brilliant. I’ve never thought of senses that was before

My aussie pup is absolutely loving watching!!! He got stoked as soon as he saw your backpack, because I've been wearing mine when we go out to get him used to it

Some galaxies had a 10 billion year head start before ours. Surely by now . . . .!

I suspect we're looking at it the wrong way. Life is probably very common in the known universe. But how common are tool users? How common are civilizations that have an interest in using the electromagnetic spectrum? We're basing our findings on use of the EM spectrum. Is that a valid metric?

The universe is too large for there not to be other forms of life in it. The problem with thinking about it is that we think that all life in the universe must conform to our limited understanding of the universe (meaning we don't really know what to look for) and that other life, whether it's more advanced than us or not, may be equally as limited in terms of exploration (meaning we can't find each other even though we're looking). As much as science is about facts and hypotheses, we assume too much.

I like how he expkains it and compares it to where i can understand nd get it..he keeps my full attention...he reminds me of my 9th grade teachers from classes i didn't mind going to..govt nd science

I believe that we are not alone. But the thought of being alone is scary!

The possibility also exists that even if they are other intelligent life forms out there, they may not be appreciably more advanced than ourselves. Yes the universe is 13.8 billion years old and the earth is only 4.5 billion. However that does not necessarily mean that other civilizations have billions of years head start on us. Generations of stars had to live out their entire life cycles, then explode in supernovae, simply to make the heavier elements from which we...and our solar system are made. It's pretty awe inspiring to realise that we are as much a natural part of this universe as a star, planet, comet or anything else. As such we are currently the only case we know of that universe becoming self-aware.

Before we worry about intelligence life, we should focus on finding any life. So far we haven't found any. I do think life does exist elsewhere, but it is very rare.

Intelligence is just the thing to have to render your self extinct .... powerful stuff

Ya know if we get all these answers then we are going to end up in atleast a brief moment of " well, now what?"---thats what i want to be there for, that moment to see what humanity decides to do with these answers...and what new qiestions we can pursue.❤

The only real foundation of Fermi's paradox is our misconception of the scope of the universe.

Here’s something to blow your mind. Time spans infinitely in all directions( the past is infinite, the future is infinite). What’s the likelihood that multiple civilizations would evolve in parallel given times infinite reach. And what’s the likelihood they’d have the technology at the exact same time that we’d be conscious enough to perceive their existence (or vice versa). I say this with the understanding that humans only recently (within the last 10000 years out of the nearly 4 billion years of earth history ) formed semi advanced societies. What if they’d showed up 200000 years ago and found apes who are only capable of living in the wild, or what if they show up 3000 years from now and it’s a complete nuclear wasteland. It’s like threading a needle from a far distance. And then of course the same could be true for them, but with a timeline that happens 1 million years in the past or future.

Well summarised Dr. Tyson... "We are they"...👍

What a beautiful video about the paradox!

Extraterrestrial life will only make its self know when we can all get along with each other

I was thinking about it lately and I realise the answer to the Fermi’s paradox is quite simple: starting to count from the ancient Egypt (3150bc) it took the Mediterranean people something like 4640~ years to find the people leaving on the other side of our own planet! 😂 And we started searching for extraterrestrial life something like 70yrs ago… 😂😂😂😂 Get comfortable, Enrico: it may still take a while. 😉

It would be very sad if we were the only intelligent beings in this vast universe. What is even worse for me is if life is abundant but the technology to travel the vast reaches of space in a reasonable just doesn't exist, and the time needed to travel between the galaxies let alone the stars is just a fools undertaking.

where did this audio of Neil Degrassi originate from? Id like to know

We spend way too much time on Fermi paradox. The simplest explanation could be that space is so vast and our radio signals attenuate so quickly. Even if there is other intelligent life out there, we can't hear them and they can't hear us.

People say mathematically it’s a certainty there is other intelligent life in the universe. Considering how old it is and how much older it will get, being alive while another civilization is also meandering somewhere in the universe is a huge mathematical improbability

It's nice to read so many smart and thought provoking comments.

Thumbnail was hard asf‼️‼️🗣🗣🔥🔥🗣‼️🗣

I think the best way to describe sending radio signals into space is like dripping red food coloring into a bathtub full of water. A normal radio signal would be like a drop of food coloring lightly dripped into the bathtub... it immediately dissipates and soon the red is completely gone, too dispersed to see with the naked eye. Now we can put a lot of power behind the signal... like putting that red dye in a squirt gun. You fire that squirt gun into the water, and with some pushing strength behind it, the drop makes it a lot further before it completely dissipates. Now realize that tub of water is just our solor system, this experiment would be more accurate using an Olympic sized swimming pool.

"Claiming to be wise, they became utter fools" Rom 1:22 Acknowledge God because you know He is there before it's late

1:17 that voice crack XD

"Maybe we are they". Mind blown instantly.

The universe is so big that is mind blowing, maybe there are civilizations that we will never encounter others might have been destroyed and maybe intelligent life is so rare that we are alone, in any case we don't know and we might never ever know.

For all intents and purposes, the universe is infinite. Bearing that in mind and the infinitesimal chance that we're the only or the first planet that's developed life, I can't make myself even entertain the thought that we're alone in the universe. I know it's not how science works, but in my mind it might as well be a certainty that we're not.

one of things i think is overlooked a lotis; We always say with a universe as old as ours but actually our universe is still in its infancy. It will continue to exists for at least 100 trillion years (eventual galactic cataclysms not counted here) so why is nobody suggesting that we might be the first? Maybe we are the precursor. After all the univserse is only 14 billion years old. Its barerly passed a few percent of its total lifetime. And by the first i mean intelligent beings, altho if we're talking humans intelligent might be a bit of stretch

Finding evidence of other intelligent life in the universe is like two people separated by the atlantic ocean. We've dipped our toes in the water, swam around in it a bit, but never ever lost sight of shore. Also, we can scream as loud as we want, and we can look all we want, but no matter how hard we try, we cannot find the intelligent life living on other continents because the distances between us is so vast we can only surmise the other intelligent life it out there, but not only where, but when in time.

The most abundant thing in the universe isn't the elements that make up life. The most abundant thing in the universe is empty space. There has to be life out there, but there is even more vast emptiness between us that we may never be able to cross in order to meet one another.

Intelligence -> want more for ourselves -> disrupt the balance that's needed for the life to keep circling. Hmmm... Makes sense

This is why Fermi's friends needed an English teacher. It's not a paradox. A paradox is two logical statements that CONTRADICT each other. These two statements don't contradict each other therefore it's not a paradox. Earth is in the outer rim of the Milky Way Galaxy.

We are living the answer to the fermi paradox

We are listening to LaSteroid Daddy Hack the IV. You sir are a champ in sports and in science, who'd a thought.

It is just like things already in front of us for so long, but we never have a thought of it existing. Because, that is not what we are looking for.

Given the distances in the universe and our intelligence I don't think we could detect other "life" until now.....i believe it will happen soon

Intelligence is not necessary for but the cellular intelligence is necessary

Intelligence is free will. And it by grace we have it, this is why it makes no sense for survival . We live as gods.

ever consider we might be under Quarantine? "do not poke or feed the animals", WARNING! Beyond this point you will encounter DANGEROUS BSC SPECIES!

Maybe the universe is full of intelligent life but there is just no way to travel faster than light, not even close to the speed of life so everybody stays within their solar system and never meet their neighbors. The idea of generation ships looks like a viable solution in sci-fi movies but in reality who would want to spend their entire life inside a spaceship and have their children and grandchildren confined to that kind of life just for the possibility that somewhere out there is another habitable planet with friendly aliens

I am about to watch every video on this channel

5:58 Nice Firefly reference there with that fly-by.. ;)

There are a couple other things to consider: 1- Life took around 4 billion years to get to where we are now. If life didn't get an early start, let's say it just started, and it doesn't;t get to our level for another 4 billion years, we would be at the end of life of our star and would not have time to become spacefaring. 2- We have recently discovered organic compounds in space. It is currently believed that the early universe, as it cooled, the entirety of space would have been about the temperature of bathwater for a very long time. The new twist to the Panspermia theory is that complex organic compounds formed during this period and had been captured with ricks/asteroids. These compounds would have seemed earth with these organic compounds in the early bombardment phase of earth and that is why it appears that life sprung up so quickly.

Universe is far beyond massive. There is no chance for not existing of another intelligent life out there.

I love the way you think.

I believe we have yet to detect all the complications that allow for intelligence, let alone animation and life. I think we are just barely scratching the service when we use terms like hive mind and the brain. I believe intelligence is more universally spread out than we know And if we are ever able to get to point where we can detect these other forms we will have suddenly started to scratch a little deeper into true intelligence beyond our current comprehension.

The more I look into it the more I believe we all move along together on different dimensions on this planet. We have shared this planet for thousands and thousands of years. It explains a lot of things. With all the satellites and different devises we have looking out into space. No astrophysicist has ever seen a UFO. Even with the Nimitz they only saw them coming down from 80,000 ft. Not from space. And as far as we know this is still the only planet in the Goldilocks zone.

The most interesting thing about the Rare Earth Hypothesis as a solution to the Fermi Paradox is the necessity and number of extinction level events required. The Earth has had 5 extinction level events. For intelligent life to emerge on Earth - that was precisely what was necessary. There is no evidence of intelligent life before the last EL event. 4 was too few - 6 will be too many. If we haven't made it to the stars by the 6th EL event - that's it. Could it be intelligent life is transitory?

My answer to the Fermi paradox works a little bit like this If you look up in the sky and you don't see any civilizations yours must be first so we're first! No paradox.

The earth is a blessing for mankind

I could never work out if Neil.... (sorry can't spell whole name) was a comedian, presenter, or scientist. I think he's all three. His style is comic but what he actually says is top grade scientific philosophy.

There’s no point even thinking about whether there is advanced intelligent life in the whole universe. The universe contains trillions of galaxies and we will never know if life exists in those near infinite numbers. So the question we should be asking is is there life, intelligent or otherwise, on planets in our Milky Way Galaxy other than here on earth. But there could be millions of planets with life in the Milky Way without a single one with a technological advanced civilisation. If you look at the history of life on our planet you will come to understand how unlikely our civilisation is. Vast reserves of oil and coal were crucial but only exist because of climatic flukes in the deep time of our planet, there was nothing inevitable about it. As for interstellar travel, I think we vastly underestimate how hostile space is to life, and also vastly underestimate how difficult it would be to successfully travel those vast distances.

"Maybe we _are_ the aliens?" As usual, he nails it. We're so convinced there has been intelligent life before us, but what if we're the first born?

It's wise to assume that the reason we haven't ran into anything resembling alien civilizations because we are probably meant to be the first precursor, as in the first space faring species before all others, the one that other species will look up to and do research on a few millennia down the line.

Theres also the “Great filter” hypothesis. We havent seen aliens, because before a civilization reaches a texhnological state that allows for advanced interstellar travel, the civilization will have collapsed from various factors. Such as wars, natural ressource exhaustion etc.

5:02 Nature? What's Nature. Is it smart enough to produce intelligent life? Is it chaos? Because symmetry and motive to build up things do not come from randomness. You need program (plan how to build) , you need motive (what for).

There are two very good possible reasons we have not found evidence of others life in the universe...1 that life may be too far away for us to detect....2 WE ARE THE FIRST.

Humanity is, very slowly, discovering the answer to this paradox.

The Fermi paradox doesn't consider distance between planets where life is possible! And as the space is expanding, it becomes even more unlikely where meeting other life would happen!

Word 👍

“Trees haven’t figured out how to move??” 😂😂

I like the idea of being alone. This means the universe and all its treasure belongs to us.

Here's my solution to the Fermi Paradox: As a species' intelligence evolves, its technology advances linearly as evidenced by our first reaching the Copper Age, then the Bronze Age, Iron Age...Industrial Revolution ... Information Age ... AI Age, and so on. Moving forward along this path, it is likely that humankind will arrive at an ability to create absolute immersive artificial environments which are indistinguishable from reality. In these environments, we will be able to do, be, accomplish and experience anything we desire. It is entirely possible that we achieve that level of technology before we develop a technology that would permit faster-than-light travel. Even if we were able to overcome the universe's speed limit of 186,000/miles per second, why would we want to risk the inherent dangers? What is "out there" that we couldn't conjur up ourselves as a virtual/augmented reality environment? In all likelihood, we will remain in our neighborhood (perhaps terraforming Mars and possibly a moon or two in our solar system). And other civilizations in far off galaxies have probably done the same. What could possibly be accomplished by sitting in a spaceship for years over what we could artificially manufacture for ourselves?

There are two possible solutions: 1. Life in the Universe aren’t that advanced or has just begun their livelihood, which makes us the most advanced species in the universe Or… 2. Life in the Universe is so ADVANCE that we don’t have the technology to find them due to their advances of technology, which makes them the masters of the universe.

Life finds a way.

One mistake we often do when talking about colonising the universe is forgetting about Einstein and just look what could be theoretically possible. According to Einstein nothing can travel faster than light and the energy needed to speed up is getting bigger and bigger the closer you get to the speed of light. Until you need infinite energy to reach the speed of light. Scientists have many nice ideas about theoretically possible forms of energy that could make faster than light travel possible and theroretically possible materials that could contain this energy. But what if there just arend't such exotic energy sources and materials? What if Einstein is right and you just can't travel faster than light? This would mean that even the most advanced godlike civilisation would be stuck with sub lightspeed travel and that it would travel with just a fracture of the speed of light because going faster would cost to much energy. Which would make leaving there solar system with anything other than generation ships unpractical. So civilisations will stay in their solar system until it becomes inhabitable and just then make efforts to travel to other solar systems to find a place to stay. Until this solar system becomes inhabitable and they have to move again. Maybe that's the reason why we never encountered aliens. Because it's simply not possible to beat Einstein.

The complete evasiveness of how rare life is was very tricky. Phosphorous is the "other" element that is KEY to life on Earth and is only created by Supernova close to a forming Solar system. Our solar system was flooded with Phosphorous early on and that was a sheer accident. Try growing any plant without it and you will fail.

Somebody has to be first, what if we are the first species in the universe to become this advanced?

Everytime I hear "Life as we define it" I have to ask if that is not the problem. We're looking for something that matches OUR definition of life, something that we recognize along the lines of something OUR planet would produce. What if just as switching continents, altitudes, above or below the surface of the oceans, or even forests, life on this planet changes in fairly significant ways, changing planets or solar systems etc changes in even larger ways. What if we have neighbors the next solar system over but don't realize it because it is so alien to our own ways that we can't recognize it (nor it us)?

Its a matter of timing, and distance.

This just reminded me of the book: We Are Legion (We Are Bob) (Bobiverse Book 1) There should be a movie about this. But it will not be popular because it will be very polarizing.

Maybe we are they!!!!!!. That was amazing.

Maybe it is because Einstein was right that nothing substantial can travel faster than light. It takes a lot energy per pound to send anything into space. In other words sending John Deere tractors to planets out of our solar system will never be possible. Also the time frames involved would most likely be longer than any biological unit could have. The only thing that would be practical to move over those distances would be knowledge and lets face it we don't have much of that.

'maybe we are they' that's terrifying

The universe is teeming with life. I do not have enough faith to believe otherwise. You're welcome.

this stuff is so damn interesting.

Never agreed on the statement "if there are other intelligent life out there we would have seen them by now" Come on we can today just barely see a few close planets if they have oxygen and thats it. Also if they are at they stage as us they wouldnt have gone anywhere.

“Intelligence as we have defined it” what he’s point at to me is that we have maybe miss-defined intelligence so horribly that we can’t find it in the fossil record.

We would someday for sure

This reminds me of when a teacher asked a bunch of students about a World War 1 plane where there was a bunch of bullet holes all over it and ask where the armor need to be, and everyone thought that they needed to be in the places where there were lots of bullets, but in fact the truth. The reality is any plane that got shot in the place where there wasn't bullets didn't make it back and thereforeneed the armor where the bulletsaren't at. A smart amimal wouldn't die somwhere that would get itself fossilized. 🤯

The million dollar question is NOT if there’s Life in the Universe or even Intelligent Life.. BUT If there’s Self Conscious Life out there that has evolved long enough technically to InterGalactilly Travel

it isn't a question of " Where is Everybody " it's a question of " When is Everybody in Time " It took us 4.5 Billion years to reach this point in time...how many " intelligent " civilizations in other galaxies living on another planet, have come and gone....and I'll venture a guess some of those planets with intelligent life met a really bad ending.

Fermi Theory, and yes Neil-IQ123, intelligence is rare.

videos like this make many people brains short circuit as they can not grasb their toughts around the point of this video.. thats why we have people that refuse to be open to the idea we are not alone in the cosmos.. i know 1 dude from i was young that was close minded out of fear.. or ability to think outside the box

Imagine if aliens did visit our planet, but maybe like millions of years ago when it was before the dinosaur, and move on to another system, because for them it was no life or something like that, why would they even come back? If they catalog our planet as non sustainable to have life? So I’m guessing the same could be said to those millions of planet that we basically identify as non sustainable but will most likely do have but millions of years from now.
