What answer to the Fermi paradox do you think is correct? Is there extraterrestrial life out there, and if so, why haven't we detected it yet?

I am not convinced the Fermi Paradox even applies in a universe that has at least one boundary in time. In a steady state universe, which was still a going theory when Fermi asked "Where are they?", then yes, you have an infinite amount of time for any species that might arise to spread to the entire universe. In a time-limited universe, it may well take a certain amount of time for enough metals (in the astrophysical sense) to accumulate to make life, and then intelligent life, a reasonable proposition. And assuming there's no shortcut around the speed limit imposed by light, there's only so far that even the oldest civilization could have reached by now. If we take Earth as average (applying the principle of mediocrity, that we're much more likely to be typical than special), abiogenesis needed somewhere in the vicinity of nine to ten billion years to happen, to form worlds with a generation or two of supernovae ash embedded in them that provides the necessary carbon and oxygen and phosphorus and iron and other 'metals' upon which to develop life, and again assuming Earth is average, it takes 2.5 to 3 billion years to progress from microbes to multicellular life, then another .5 to 1 billion years to evolve intelligence. No paradox remains, we're among several sentient races that have arisen in the last 13.8 billion years. And no one outside of about 200 light years can know we're here anyway, since that's around the earliest date at which pollutants (becoming important about 200 years ago at the start of the Industrial Revolution) could be detected in our atmosphere by a sufficiently powerful spectroscope. And again, assuming Einstein's speed limit is a hard fact, then no one outside of about a 100ly radius can have conceivably both a) detected we exist by atmospheric pollutants and b) immediately mounted a mission to check us out. Compare that 100ly radius, to the actual size of the universe. No, it seems unspeakably unlikely that anyone has noticed us, even if as a matter of statistics, it's unspeakably likely that there are other intelligences in the universe. Thus, I assert the Fermi Paradox isn't a paradox, because the failure to see other intelligences is due to the fact that the universe had a beginning, and that the speed of light is a limit.

The universe is billions of years old and ever expanding. I firmly believe that when the universe was younger, and stars and galaxies closer, their were many species of aliens traversing the universe. Like an intergalactic highway. But as everyone drifted further and further apart the distance became to far and everyone is now isolated by light years and forgotten.

I’m positive there is life and intelligent life out there in the Universe, but what if life only ever evolves to be as intelligent as it needs to be based on its environment? If they faced the same general pressures that early humans faced (predators, climate, etc) it could be argued another species would evolve only to a threshold of intelligence, at which point they are able to adequately survive within their environments. Therefor, it may be possible most intelligent life is as intelligent as we are, not much more or not much less. The only difference would be the amount of history an extraterrestrial species would have compared to us, if it’s significantly more than ours then extraterrestrial life would be that much more advanced.

I remember reading a newspaper article a few decades ago that quoted an eminent astronomer's estimate of the frequency of planets orbiting other stars. I've forgotten who it was - but he said that, so far as astronomers could tell, our solar system was the only solar system with planets, and that planets were probably extremely rare in the rest of the galaxy. He was pretty certain that the formation of the solar system was an anomaly. He said we had to face the fact that planets outside the solar system would probably turn out to be science fiction. And we all know how well his educated guesses have aged. The galaxy is pretty big. Our radio signals have penetrated less than 200 light years of it so far. We know of just one sample of what kinds of life are possible. And our understanding of physics is (sorry Professor Tyson) still primitive, no matter how solid and certain big parts of it seem to be to us. There may be a constant chatter of interstellar communication passing through our solar system, and if so, it's using as-yet-undiscovered (and currently considered to be impossible) physics, since electromagnetic radiation is so slow. If it's there (pure speculation) it is between kinds of life and types of intelligences that will eventually astonish us. I'm comfortable with not knowing if there's intelligent life out there, and comfortable with failing to detect intelligent life if it is out there. My guess is that yes, there's complex life, including intelligent life, all over the galaxy - but all of our guesses about extra-solar-system intelligences and interstellar communication will probably be wrong, and if we survive to continue our explorations, I think life in the galaxy will turn out to be far more complex and interesting than anything we can imagine.

So true. He's a great teacher becasue of this. I had an IT instructor at San Diego Community College named Robert Martin that would go deep into the mechanics of various IT subjects, even though they sometimes weren't directly related to that specific class. When I took my first networking class, I already knew it all (and then some) just from the deep dives Robert did. I learned like 3 different classes worth of knowledge in that single class because of this. Neil does the same thing.

I've been the #1 fan of Dr Carl Sagan since my version of first contact via the television with him, albeit one-way-contact. Moreover, he still lives in my heart even after his passing. Then you came along, Dr Tyson. You are carrying-on his legacy and this video just exemplifies or shows me that you are the one who carries the torch of science, knowledge and curiosity. You make science of learning fun. So, thank-you to the both of you for this video. It is appreciated, infinitly.

If Chuck had pursued Astrophysics, he would unravel the mysteries of the Universe, every episode. Remarkably intelligent man.

This show is so underrated. Neil is so captivating with his knowledge a out the universe and Chuck keeps the belly laughs coming. This is my favorite show to listen to on my 2 hour long drive into work.

chuck definitely deserves an honorary doctorate!!! love what you guys do!!!!

Excellent explanation of the assumptions in the Fermi Paradox. It’s more than the question, “ where is everybody”.

26:00 I think with a dialectic mirror room with one room observer on other side you actually can see in direct line, but it will be better with high quality camera to see how far you can get. I think it's nearly to infinity depending on how further away observer can proceed..

Chuck has quite literally made me a massive fan of science. Sure i might have liked it a little before, but without chuck i wouldnt be watching every single video for the past three years keep up the great work boys!

Chuck lays the butter on pretty thick in this one, and Neil just takes it in like warm toast.

3:30 surprised Neil didn't mention that larger planets than Earth could have too strong of gravity, and they might not even be able to reach escape velocity.

The fact that all galaxies will become islands has always been wild to me. There will be civilizations in them. And they will have no possible way to know about the universe. It makes me wonder what did we miss by coming into existence at this point in time ?

Oh wow someone from my podunk town in the middle of Wisconsin got their question answered on here that’s awesome!!!!!!!

"Nobody likes rats."--Neil deGrasse Tyson Love it!!!

Yes! A galactic gumbo episode!!!

The question about being Hawking-radiated while inside a black hole was brilliant. Sure, relativity tells us that an observer "inside" a black hole would see the future universe play out before their eyes, but I never thought about the black hole itself aging (and shrinking) while this is happening.

@StarTalk something interesting Matt Burk brought up allowed me to make the connection of the expansion speed of space and a black hole are both unobservable to the eye, this could very well be an explanation/connection that a black hole is in fact a portal to an entire different universe itself.

I also have a theory about dark matter/energy. What if it's particles or something larger, let's just say matter, moving faster than light? That's why we can't see it but some of its energy is still remaining. So Dark Matter is what's moving and Dark Energy is the remaining energy. It could be faster than light and time.....

I read or heard somewhere that "The Sol System" (Name of our star system), anyway. That "The Sol System" is a 3rd generation star system. Meaning 11st generation of stars exploded, then formed 2nd gen, then exploded making even more elements, then seeding what become would become our system and others as the 3rd generation of star formation. also that we though that hw we get heavier elements other than them being made in the explosion of neutron stars.

Hola... Gustavo Silva from Mexico.... Question, did we have locate the center from the big bang should start? If so the universe is expanding from it, like any explosion, is it expanding in different velocities according to the matter in between the expansion?

Hysterical. Chuck rocks stand up. I forgot about the word hegemony. A dangerous characteristic.

Here's a solution to the paradox: there's already a type 4 civilization that conquered most of galaxies but to prevent hegemony self destruction they created dark energy halos around every galaxy in a way there's only 1 civilization per galaxy so no one can see each other

Voting for Chuck to get a diploma.

Mr. Neil I had a thought what if the big rip isn't the end but the beginning of something like a connection to the multiverse or some other greater evolution for our universe and/or reality.

Isaac Arthur has a really nice exploration of the Fermi Paradox.

@10:42 possibly my favorite Star Talk clip

One concept I am attempting to understand (2-parter) is: 1) if our universe is infinitely expanding, what is it expanding into? This question extends to (2): if we calculated by looking back into time at the early universe to understand that the universe is expanding because of cosmic radiation, can we look "forward" past the oldest part of the universe to see what the universe is expanding into? My question is derived from the illustration that was created to show what science believes our universe looks like. So, what is the oldest part of the illustration expanding into?

Love the show. I can gain so much knowledge and laugh like I'm at a comedy show as well. Love it! PS: My theory on why we don't run into other lifeforms is because of the intelligence level. Would you go find & communicate with an already developed ant colony? Would you try to communicate with the ants or fly by study/observe. Then keep data with how they're living and developing. You would pick studying everytime since we already know their intelligence level. We also have the knowledge on how big planet earth totally is but ants don't have a clue that my backyard isn't all there is out there beyond their limits of comprehension.

What temperature is the mirror? Does it emit IR?

Does anybody know if they already did the abbreviation explainer?

Perspective seems to be relevant to any question regarding everything. Observation influences perceived reality... How can we ever hope to know what the "natural" state of anything is ?

At what point does chuck get an honorary degree. Because i know he’s absorbing all this information. This is line a personal brilliant instructor and some episodes he get more than one.

I love that mirror question

28:23 Can you please do a video on the cosmic event horizon. The proposed edge, with the expansion of the universe, at the speed of light, in which light emitted past that region. What does the light due when the light redshifts below the speed of that expansion? With the creation of a biosEinstein condensate, lasers where used to lower the temperature, by lowering the frequency of the laser light. Would there be a similar effect? What was the background temperature, 0.0003 Kelvin? Would there be a point in which light would be stretched into a BEC?

Tough questions this round!
