You are assuming that we won't discover new laws of physics where faster than light travel is possible, and not very costly. Perhaps the extra-terrestrials have already discovered this.

[@mistermisfit4104]

There are no 'new' laws of physics. Just more complete and correct versions. But yes. Awfully ignorant to assume that what we know now is ALL there is to be known :)

[@geoden]

There are LAWS of physics, we may discover many new things but they will be adjuncts to something we already know. We will NEVER exceed light speed. It's a law that will never change, ask any physicist. I confidently predict they will all agree. Unless one KNOWS extra-terrestrials exist, (nobody knows) there are logically none. I applaud people interested in physics but I beseech you to listen to the best cosmologists, there are a few around on YT, it will enhance your life.

[@geoden]

Science says you're wrong. Nothing can ever exceed the speed of light and never will.

[@bozo5632]

And you are assuming we will?

[@telman222]

here is a quote from a famous science fiction writer of a past generation: “The main thing about aliens is that they are alien. They feel no responsibility for fulfilling any of your expectations.” -Robert Silverberg

[@telman222]

@G Douglas you're kidding right? It means we have no idea in the world how aliens think or what they can do. For example we cannot assume advanced aliens would not hurt us. They may decide that any other civilizations are a threat and be already sending a fleet to eliminate us.

[@WerkshopGI]

“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.

[@donnievance1942]

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.

[@imbra]

@@donnievance1942 Your first point is spot on! We have this physics thing figured out almost completely, we just need to iron out a few kinks and details and we will have a complete, 100% accurate model of reality. The arrogance that is needed to believe that assumption is mind boggling.

The fact aliens aren't here already means the distances involved are too big for any intelligent life to cross. And it also means there will never be any time in the future when this will be possible (because it would have happened already).

[@bo3bdallah56]

Probably there is an intelligent life , and common across the universe , but they did not reach the technology what human have nowadays , like what we were before 300 years ago . I think it is possible that human will be the first intelligent creatures who will travel across the universe within few decades or centuries .

[@aucourant9998]

@@bo3bdallah56 I really don't think so. When you consider the number of planets before us in previous solar systems that have gone on for hundreds of millions of years developing intelligent life and none of them has never managed to cross to other systems, why should we think this one little planet should be the one to do it?

[@brud1729]

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.

[@wildone106]

How would you recognize them if they were here? If they made it here they would definitely be able to minimize or completely hide their presence

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.

If we just set and STARE out at Mars LONG ENOUGH, as Dr Park suggests sooner or later our environment will certainly be destabilized and our society will either collapse, or humans will go extinct!

Silly statement from an intelligent man.

[@mintakan003]

The only way I can see "humans" doing interstellar travel, is in some distant "post-human" future. This can mean uploading minds to machines. 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.

@@joeyb8225 Actaully it goes right back to Laplace who said the same but in different words. As for its validity. See below. "ECREE is related to Occam's razor in the sense that according to such a heuristic, simpler explanations are preferred to more complicated ones. Only in situations where extraordinary evidence exists would an extraordinary claim be the simplest explanation.[2] A routinized form of this appears in hypothesis testing where the hypothesis that there is no evidence for the proposed phenomenon, what is known as the "null hypothesis", is preferred. The formal argument involves assigning a stronger Bayesian prior to the acceptance of the null hypothesis as opposed to its rejection.[3] How to weigh such priors requires careful consideration, and it is usually at this point that arguments between those who make extraordinary claims and those who debunk them occur." en.m.wikipedia.org/wiki/Sagan_standard

[@joeyb8225]

@@martinw245 "The origin of ECREE lies in eighteenth-century Enlightenment criticisms of miracles. The most important of these was Hume’s essay On Miracles. Hume precisely defined an extraordinary claim as one that is directly contradicted by a massive amount of existing evidence. For a claim to qualify as extraordinary there must exist overwhelming empirical data of the exact antithesis. Extraordinary evidence is not a separate category or type of evidence--it is an extraordinarily large number of observations. Claims that are merely novel or those which violate human consensus are not properly characterized as extraordinary. Science does not contemplate two types of evidence. The misuse of ECREE to suppress innovation and maintain orthodoxy should be avoided as it must inevitably retard the scientific goal of establishing reliable knowledge." -David Deming I'll go with the history and proper use of the standard as described by the Director of Malcolm Wiener Center for Social Policy at the Harvard Kennedy School over Wikipedia. That being said, I don't see the massive amount of contradictory existing evidence and/or "overwhelming empirical data of the exact antithesis" needed to make the claim extraordinary. In this case there would need to be a massive amount of empirical evidence proving we know all there is to know about the physics involved in the endeavor of space travel. Also, we would do well to remember, the claim in this video is actually being made by Robert Park. So, I say, let him prove his claim.

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

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.

So our point of reference, indeed, come from Heinlein, and Roddenberry. So this is really just rhetorical stuff. My concept is that aliens are our biological cousins and we share some percentage of dna and a common ancestor with them. So our physical limitation would likely be their's. Since we can not possibly meet them physically, the only other way, still an unexplored scientific frontier (owing to the problem of objective measurement) is via our consciousness. Do you know where thoughts come from, creativity? Its mysterious stuff. Objectively, it's a function of our living body, a phenomenon of our living body that we do not understand. [I don't say "brain" because brain is just a component of whole living person and only the whole thing is "alive" and can have consciousness, not the individual atoms, molecules, tissue, and organs.].

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!

Is this how UFO kidnap cows?

[@UTock]

@@xspotbox4400 they use antigravity to lift the cows

[@2010sunshine]

Wonderful discussion

[@waldwassermann]

Alien means Other so technically speaking Aliens are always here.

[@alexsmith2526]

the fact is me spend our whole life travelling through space orbiting a star -but in the end in our perspective we are going no where ---

[@xspotbox4400]

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.

Why do Aliens stay up so late

[@TimmyTues]

Or are they? If they are advanced enough to get here, it would be relatively easy to evade our modes of detection. Pretty simple.

Life's prevalence is a function of the "law of minimum". Elemental distribution is not uniform throughout the cosmos, especially backward in time. If life is rare now, it may not always be so.

[@anton1949]

That they have not 'visited' us is proof enough that there is intelligent life out there.

[@jamesruscheinski8602]

Maybe there is way to detect plant life on other planets in galaxy from natural radiation or other measurement?

[@bernardliu8526]

The bad news is we’re not going there. The good news is they’re not coming here. Such a cosmically funny joke !

[@skylershank9309]

How do we know aliens aren't here?

[@Cyberdactyl]

We are no closer to explaining abiogenesis than we were in 1952 with Miller-Urey. Until one of these CTT episodes have the sack to address it, all these interviews are silly.

[@Skankhunt420.]

He dismisses a lot of things. Saying its not going to happen is naive because he cant predict future technology. Watching this guy on this laptop would have been considered magic only a hundred years ago. We may figure out how to travel faster than the speed of light and we may not need to ask our kids to go if we can figure out how to increase our life expectancies without having cell degradation. Maybe we could just simulate another universe and find life there

[@lustxglory]

life is bountiful, is there a afterlife?

[@abelipson9040]

Yes there is after life but not what we imagine it to be. It is everywhere as it is all connected by E=mc2 ( Einstein) life and all is much more than a body or what you see..mountains make lava, sand makes glass, gravel makes rocks, rocks make sand, people make people, animals make other animals, leaves CRUMBLE and make land filler, food makes bodies...what do you mean saying is there an after life. Read this, open your eyes, there is after so called life all around you..even invisibly Sun's rays, neutrons, atoms, electrons and what have you.

[@abelipson9040]

We don't change into another person in the future ..we are part and parcel of millions of other things and predecessors coming from smaller other things or even bigger things.

[@UTock]

They are already here...bases in our oceans

[@SmashedBanana100]

ight bet

Also the dark side of the moon, alongside the Nazi moon bases.

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.

I think they're visiting us already. I think the government knows and has been trying to hide it for decades.
