Robert Park - Why Aren’t Aliens Already Here?

It seems absurd in a universe with 100 billion galaxies, each with billions of stars and planets, that we are the only intelligent life. So where are all the others? This is the famous 'Fermi Paradox,' asked by Nobel Laureate Enrico Fermi. By any reasonable calculation, we should see evidence of other civilizations all over the universe, but we see nothing.

    “It’s hard to imagine…” his lack of imagination is staggering. 9 weeks before the Wright Brother’s first flight in 1903 the NY Times said manned flight was between 1 and 10 million years away. Just 2 years before the Engineer in Chief of the Navy said it was a “vain fantasy”. 63 years after first flight we landed on the moon. The technology you’re using right now to look at this message is millions of times more powerful than that used to put the first people into space. If we can survive our own inhumanity we can get to the stars and traverse spacetime in ways people have yet to imagine, and given the vastness of the cosmos some civilization has already done it.

    All these experts being asked this question seem to take off from the same set of unexamined assumptions: 1) The state of our knowledge of physics is comprehensive and final enough that we can apply the limitations (speed of light, etc.) that we know about to the capabilities of another, perhaps much older, civilization. 2) Other civilizations are confined to moving through the matrix of our observed flat 4D spacetime. They also adopt the debunkers' attitude to what has now become compelling evidence that there is a huge presence of conventionally unexplainable phenomena manifesting themselves almost daily around this planet. I cannot, in this comment, go down the rabbit hole of trying to argue that last point, but I know personally that these phenomena are real and have no conventional explanation. Anyway, at this point the debunkers are ignoring the weight of evidence accumulated in the military sphere, despite the coy equivocations of recent official pronouncements on the subject. Please notice what the military didn't say in their report to Congress-- that they had ruled out the possibility that we are being visited by an extraterrestrial presence. They chose to totally avoid mentioning that hypothesis, something they never would have done if they had a basis to take it down. They knew as well that if they broached the subject they would open themselves up to a deluge of contrary evidence from the record and would have to discredit legions of their own personnel, so they opted to not allow the topic into discussion. They wouldn't even put themselves on record as saying that they rejected the extraterrestrial hypothesis. They got burned decades ago when they tried to use the crude debunking methods of denial, mockery, and falsification of the record in Project Grudge, Bluebook, and the Condon report. So now they pretend that they are addressing the UAP phenomenon respectfully, but passively sidestep any discussion of the ET hypothesis with finely calculated sophistical rhetoric. The experts interviewed by Closer to Truth all adopt this approach to the subject. This is so predictable in these videos that I believe Kuhn is grinding his own ax on this subject, and not carrying out a real enquiry at all.

    One also has to consider the precise timing needed for us to receive communication from intelligent alien civilizations. For example, if a robust alien civilization across the Milky Way galaxy had a similar evolution to ours, but where the asteroid that killed the last remaining block to the age of mammals, the dinosaurs, was a 10 thousand years earlier than ours, their civilization could have come and gone by the time we discovered electricity, or the radio. Thus we'd never know of their existence and they'd have never known or ours. The same is true across the universe, but in much larger time scales.

    I think there is Intelligent life in our galaxy alone, that exist at the moment. But with the vast distances, separating us , we are all isolated from each other, and we are probably never meant to meet. The nearest star to us outside the solar system is Proxima centauri which is 4.2 something light years away, about 5 thousand times thurther from the sun to the orbits of Pluto or Neptune ,and that is the nearest star. It would take about 60+ thousand years to reach it with the fastest probe ever built. So any intelligent life form would have their work cut out traveling these vast distance, so would it be worth bothering.

Or our AI descendants that share our values and sensibilities, and hence, "human" in that sense. As for getting there, Breakthrough Starshot provides a clue on how this can be done. Of course, for larger crafts, we would probably need much larger lasers, a space infrastructure, powered by the sun. (Haven't figured out a way to slow down yet.)

    When Dr. Park talks about how he would have his students theoretically 'plan a trip to the stars' and quickly come to the conclusion that we can't 'go there' and they can't 'come here' does not account for the fact that we really don't know much about the universe, space, or time. Approximately 182 years ago, the first settlers traveled by covered wagon from the east coast to the west coast. It took seven months. The thought that less than 200 years later an SR71 Blackbird could fly from coast to coast in 68 minutes and 17 seconds would have been a laughable prediction. 200 years from now, we my very well learn that Einstein was wrong about nothing traveling faster than the speed of light.

If someone cannot discuss it without considering the fact that other forms of life may have some form that we cannot imagine, that there are additional dimensions that we do not understand, and that “power“ sources out there could be far beyond our wildest imagination, then we will never understand.

    As he notes with his discussion of robots and telescopes, WE wouldn't have to go. We could send automation. Still perhaps a long way away, but with the AI and machine learning we're already developing, it could conceivably happen a lot sooner than we think. Like decades, even. Also, we can't assume that no intelligent life could have developed the technology to get here. Likely that hasn't happened yet, but we can't rule out the possibility that it has happened or could be possible.

    it doesn't have to be biology form of human to be sent to other planets. Human also may be able to transform into non-biology form of body. It also doesn't have to be AI bot. We may be able to get rid of biological form of body and still have our brain and consciousness in a metal body. I don't know how long that body can last but definitively will last much long than a biological ones. We have to go explore other planets in the future regardless how much energy will take. I thought of using Dyson sphere to generate the initial boost of energy to push a star ship to 10% of speed of light and then slowly increase the speed through decades to about 50% of speed of light, that may achieve inter planetary travel

    Even if somebody could invent a warp drive in his garage, don't have hopes for flaying cars anytime soon, they would became available only after military science will release some spin of principles and allow mass production of much weaker and totally limited consumer version that can't be used for crafting original invention with a full potential. Imagine we could compress space front of our flaying car, E=mc2, this means take mass of a car and multiply it by square of a light speed, result would be more energy than it's contained in entire universe. A car flaying faster than light crushing on Earth would probably take entire solar system along with it, rather say entire galaxy could get blown apart, providing only a fraction of total kinetic energy would get transformed into a force. Or somebody could just fly by and drop a marble, this tinny object would release enough energy to blow a planet apart. Doesn't even need to travel faster than light, mass of a marble times c2 is more than enough. Nothing like that could be seen out there in space, so we should conclude two possibilities, either it's really impossible to move that fast like theory dictate or there must be a flaw in that equation simply nobody can figure out. Barren planets are telling us a story as they are, life is not meant to exist everywhere in space or entire universe would turn into a jungle and everybody would be hiding in asteroids, flaying away from space tiger aliens. Than there's also a third possibility nobody want to touch and play with, universe might not be as it seems.

    The Fermi Paradox explained. There is a beautiful loving Universe many people claim they experience when they are undergoing an NDE. Long before any Advanced Civilization gains the technology necessary for Interstellar Travel - they find a way to escape to that Universe. In other words, it is technologically easier to get to that other very pleasant and safer place, than it is to develop the Type II Civilization Technology necessary for Interstellar Travel. This explains why we have found no sign of an Advanced Alien Civilization anywhere in the Universe.

Silly statement from an intelligent man.

    Sorry - but I don't think this guy is on the right page! He's drawing too many conclusions from little evidence. For example he talks about the human life-span not being long enough for a journey to Earth. We are not necessarily talking about 'humans' as we know them. Also, he talks about calculating the amount of 'energy' required for space-travel. Just over 100 years ago - on this planet, atomic energy was unheard of. This chap is so full of his own assumptions that he could argue for a flat earth!

  • @geoden

    Robert Park is right. There are a few reasons why I think we will never see or meet alien intelligent life. Firstly, if alien life exists it must be very close to us or will be much too far away. Secondly, we will never exceed light speed, nothing can. Thirdly, human lifetimes are far too short. Let's examine the first option. If alien life was close, within a radio contactable distance, we would know about it already. So far we have heard nothing, SETI keeps listening but again, nothing. In my young days I hoped I might meet aliens before I die. Sadly, I must abandon that hope. The second fact is that the speed of light is insurmountable for us or aliens, nothing having a rest mass greater than zero can travel faster than light, photons, the particles of light, travel at light speed because they are massless. Worse still, travelling anywhere would require an enormous quantity of fuel, assuming we had it, we then face the fact that the mass of our vehicle increases with speed, this would severely limit our speed and extend the time taken to reach a destination. That makes the second option a no-go one. The third option is even worse, even if we could travel at the very optimistic speed of 1000th the speed of light with unlimited fuel, it would take thousands of years to even escape our parent galaxy! Clearly we would be living in a dream, it's never going to happen. Forget about warp drives, wormholes etc, they are pie in the sky that will never materialise. Anything having mass (and everything except photons does) is stuck in it's local area. This Universe is vast beyond human conception. Thinking philosophically, it's probably a good thing too, at least we know we won't be invaded from space.

    NASA invited scientists and science fiction writers and fantasy artists to meet one day in 1999, I think it was. The cross fertilization of ideas was invigorating. Now, here's a thought. We are here now with our radio transmitters sending "I Love Lucy" out into the universe, which is 13.8 billion years old. Our planet is only 4.5 billion years old, and it made us. WHY NOT THIS: When the universe was 12 billion years old, another planet was 3 billon years old, and the people on that planet found a way to upload their minds into self-repairing artificial bodies with interchangeable parts, including the brain part that holds the mind. Now, they scatter about the galaxy on the inside of giant, moon-size ships, living for generations happily traveling. They visit Earth--a billion years ago! Or a billion years from now! Intelligent MANKIND has walked on this planet a quarter million years and might continue to do so for a billion more. We will meet aliens someday. The odds say so. And it could be a million years from now, or it could be next Tuesday!

    I don't see any reasonable way this would happen. Any aliens that could make it here would have had to master interstellar travel. What would be their interest in this planet? Resources? If they have mastered interstellar travel, they have literally millions of stars with planets within easy reach -- basically unlimited resources. They would probably understand their own history -- they would know how hard it is for any civilization to go from microbes to interstellar space flight, and they would know how relatively rare that is. There is no way we would be any kind of threat to them -- by the time we are able to travel to other stars, our own interest will be curiosity rather than resources. I'm sure they'd be fascinated by our own journey, just as we would be fascinated by theirs. No, absolutely nothing to worry about. We have a LOT more to fear from ourselves -- far more than any alien species.
