@@philliprobinson129 this is an argument you can make in response to any claim. You can ALWAYS say that, "well our knowledge always changes so this could be wrong in the future." True. Absolute certainty is never possible. We can't know with absolute certainty whether or not the sun will rise tomorrow, whether other humans other than yourself really exist, whether you're a brain in a vat, etc. Our future states of knowledge will always change. Rather than state that obvious fact and say "knowledge will change so this may not be true", you should take what we know today and form opinions from it. If you say that we can't/shouldn't derive conclusions from what we currently understand in physics because it will change in the future, logically you have to do the same with medicine, chemistry, biology, etc. I doubt you would say that its not realistic to derive conclusions on how the heart works, or how hormones work using our current state of knowledge even though our state of knowledge if these will no doubt update in the future. It seems to me that arguments of this kind indicate confirmation bias. One wants something to be true (aliens exist and have visited us for example) and rejects the implications of all modern physics in a way they wouldn't with any other branch of scientific inquiry.

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.

There is an episode of Cosmos in which Sagan adresses the space travel and its troubles. I noticed that, unlike Drake, he explained it taking the speed of light effect on time. Sagan, for example, says we could reach the center of our galaxy in 21 years, ship time, at the speed of light. But the center of the galaxy is 30,000 light years from us, which means that this would be time passed for the organisms that didn't take part of the travel. Drake seems to think that the time will pass the same way to the passangers. One of them must be wrong.

[@twirlipofthemists3201]

They're both right. Sagan was talking about (sci fi) traveling at >99% light speed. Drake was talking about (reality) 1% light speed. Some day, with fusion or antimatter, we might go 10-30% light speed - not fast enough for time dilation to matter.

At 6:45 that is NOT all correct. True that after 40 generations enough probes exist to equal the number of stars in the Milky Way. But if stars are on average 4 light years apart (plus or minus a few light years) and it takes a million years for the self replicating probe to travel from one star to another, after 40 million years the probes have only spread out to a distance of 160 light years from point of origin.

It is exponential. Remember the distance covered by each probe is roughly the same, but they will eventually cover a large area.

The universe is telling us something it's not meant for humans to travel the stars

[@TheHighlanderprime]

Frank is a mainstream scientist who can only see it from our vantage point of course. But let’s consider that our understanding of space and space travel is incredibly limited; if so, other possibilities exist that not even Frank can wrap his head around in terms of physics. So while I respect Frank’s knowledge and perspective, I don’t think he knows the full story.

[@Man_fay_the_Bru]

Yeah but he bases his theory on facts not Star Trek😏

[@jjt1881]

Frank Drake: Father of us all. Yours are the words of wisdom. We listen in awe.

[@jean-pierredevent970]

A sort of prime directive from Startrek could forbid contact until we are ready for it. But there is more going on than that since we even observe nothing remarkable that can't be anything other than alien. So I start then wondering if it's possible to filter all our observations. That seems to take a kind of impossible big cloak around the earth, it would take enormous energy. Who knows there are other ways however.

[@jean-pierredevent970]

@Wild One Perhaps, but you certainly nail it that if aliens can hide what is (was) "really" going in the universe, then they could also hide many other things going on under our nose in the solar system. But that cloaking technique seems almost impossible. How could you do it ? A screen bigger than the earth?

[@shonuff4323]

The problem I have with the whole "space is too far" theory is that we look at the problem with out current technology and understanding of physics. That is just not a smart way to think about it. If there are civilizations out there that have been around thousands or millions of years longer than we have, they would obviously have an unimaginable understanding of physics and have insane technology. It would be like someone here on earth 2000 years ago saying how it is impossible to go to the moon. Well yeah, it was impossible with our knowledge and technology at the time.

[@ceticobr]

I think I understand your point. Why calculate the odds of inter space travel by means of our current knowledge and technology? Alien civilizations might be millions of years ahead of us, they might know things we haven't even dreamed of. While I agree with that view I also think that we do sometimes overestimate future technology capabilities. There are many amusing examples in science fiction that were written in the last century that predicted flying cars, interstellar traveling by the year 2000. The most we can *reasonably* do is to anchor our predictions on what we do know. Anything that goes beyond that is just a guess and any guess as as good as another.

[@Dra741]

The Drake equation doesn't take into consideration everything else that's out there

[@myothersoul1953]

What about the possibility that they are too small to see, at least from this distance?

[@vicpalushaj]

Boring is a good attribute for a stat if you want intelligent organisms to evolve? That’s all we look for when searching for exoplanets that could sustain life I would assume other intelligent beings would do the same

[@chrisrecord5625]

The universe is reportedly 13.8 billion years old but the earth is only 4.6 or so billion years old. Earth has had an advanced technological society, for maybe, the last 100 years. Hence, we may be part of a nascent and fertile period in the universe where a million exoplanets are developing advanced civilizations but many may only be slightly ahead or behind ours. So, wait for a couple ten thousand years to pass and let's see what evidence we have. (Although, the distance problem makes visits more problematic.)

[@rekenney100]

Fun Video ... but everything Frank noted as the "boring" attributes of our star or the exact reason it is interesting, unique and different.

[@joselo-zl5wo]

I saw three spaceships!!! I wasn't high, drunk and I'm mentally balanced (according to my friends, lol). I was w another 2 fellows who saw the same thing. Why these aliens are not showing themselves?? We don't know

[@GMVTV]

We do know. There hundreds of reasons, and many good theories & scenarios have been drawn on that. We have some intelligent, too, you speak for yourself only

[@AntonioSanchez-yl9wj]

Frank Drake is the real deal. Just put one objection, our sun is totally average and many more planets like us exist with life. But intelligent life is another category.

[@8dioproductions]

Beautiful, brilliant science mind!

[@billyjohn9192]

Who?

[@GBuckne]

..one more thing, if you can travel at or faster than the speed of light, more than likely you are not using radio waves because they are too slow...we know now that the Higgs is part of the mechanism responsible for attaining mass as you approach the speed of light, if you can alter this mechanism (which they can, haha) of the vacuum light velocity could possibly be overcome

[@drs9489]

It makes sense to me that if I was an alien species and went traveling through space looking for another intelligent species our type of stable boring Sun would be the ideal place I would start looking. Since that's the environment that produced my intelligent species. Not a sun that is brighter or drastically different in some other aspects that I can't imagine.

[@vitoamos2815]

Earth is still primal...and his answers are hypothetical...Has he spoken to aliens, wonder when they told him it was to far...

[@chuckschillingvideos]

"It's preposterous that there aren't other intelligent creatures" ORLY? Please name one, Mr. Drake. Just one. In a universe so vast, with billions of galaxies, if life is soooooooooo very easy to get going, why is there not one scintilla of evidence of it?

[@chuckschillingvideos]

@C M ahhhh....I see. And we're protected by the Men in Black, right?

[@jzamb]

Come on folks, Aliens probably zoom pass Earth all the time. First they roll-up their windows, then lock the docks, and finally get the hell away as fast as they can!
