    Nothing is set in stone, all of these are theories supported by data and the very limited knowledge we have gained on the universe. Anything can happen we don't or probably will never truly know.

    Chuck has been doing this for so long; he has been learning from Neil for so many years that he should be given an honorary degree. I mean, I get the sense that he knew everything discussed in this episode (except the one math question) but he is a consummate professional so he plays along as if he doesn't. I'm starting the campaign right here, right now: Give Chuck an honorary degree!

    The best part of this video is learning about Ground News. As "news" became more polarizing on each sides' major platforms, I stumbled on StarTalk's video with the creator of the Ad Fontes Media Bias Chart. From then on, I simply only read stories from those center/top agencies, such as AP or Reuters. Ground News not only utilizes this monitoring platform, but two other major ones I never heard of, and looks to do it in an easy to absorb and navigate interface. I am excited to subscribe, yet ultimately sad that I even have to. Thanks StarTalk!

    We'll make it to 2030 but it's not going to be pretty due to A.I. and automation decimating the workforce. Climate change accelerating also means large parts of the Earth will be uninhabitable so mass migration and water wars will be common place. Making it to 2050 is going to be the real challenge.

    What if the universe doesn’t rip? What if it gets to a point that it can no longer expand and then reverses into the squeeze? (I prefer to call it the squeeze as well). And then back out again? Is that a possibility? Love you guys and all the great content!

    I think if our universe is indeed finite, then the big crunch is most likely. Because unless our current universal iteration is the first then something either caused it externally or it's cyclical and i'm not going to add more issues with the external idea. Now just as in the big freeze eventually we couldn't see other galaxies or stars it's possible in our time we simply cannot observe the collapse because we have not yet reached that phase in our universe similarly. However the evidence implies it's likelihood, because saying currently we somehow exist in the history of all existences final end is ridiculously improbable, statistically when all data is accounted for the cyclical idea is astronomically more likely given our understanding.

    Wow!! Neil finished with an idea I had back in elementary school when I first learned about the Big Bang. I asked my teacher if it worked like a rubber band and would snap back - and could that create multiple big bangs? With the expansion, it's unlikely unless dark matter isn't causing the expansion but rather we are caught in a state of expansion caused by the force of the Big Bang and we have yet to see it slow down. I think the idea of multiple big bangs was termed Eternal Inflation or something - where there was the idea of a "loaf" that is expanding and creating multiple universes. I wonder if the expansion does actually slow and the thermo end is what occurs, would our universe just melt back into the loaf?

    Hello professor, its nice and honor to watching and hearing you . I have 2 questions if you mind to answer : 1_If we have a pool for swimming in space and closed from above to avoid water out can we swim and how much mass of body inside ? 2_on space ,o'clock tik tok tik tok will move slowly or normal , and a compass will take or show direction ? I'm Akram Saleh from Saudi Arabia

    I'm not a professor but I think I can answer: 1. Yes you can swim in a pool in zero gravity, however you will need scuba tanks or a similar way to breathe because the water will not stay on the bottom of the tank (in zero gravity, there is no down or up). So you can't come up for air, there is no 'up'. The water's surface tension will make it cling to your face, instead of falling off your face due to gravity like it does on Earth. Swimming in zero gravity is very dangerous. "how much mass of body inside" : Mass does not change when you go to space, weight does. Weight is the force gravity puts on a mass. In space with the rocket engine switched off everything is weightless, the same would apply when swimming. However you and the water would still have the same mass as on Earth. 2. Gravity makes time run slower. Clocks therefore run a bit faster in space compared to on Earth's surface. The difference is very small, you need a special atomic clock to measure the difference, however people have put atomic clocks on aircraft and flew them around for a while and noted the small time difference so the effect has been proven. 3. A compass works by indicating the direction of a magnetic field. Earth's magnetic field extends a long way into space so a compass should work many hundreds or thousands of kilometres above the earth. A compass isn't accurate near the magnetic poles on the Earth's surface, it will be even less accurate near the poles in space, but otherwise should work until you go far enough away to exit the magnetic field.

    Question that doesn't fit the topic. Suppose I wanted to travel forward in time. I build myself a space ship that can travel at large percentages of the speed of light. My clock slows down while I observe the universe aging faster. Would I accelerate relativistic effects even further if I got as close to a black hole as I could and orbited it for as long as I could hold that orbit? Also, since you can get nearer a very large black hole without extreme effects than you can a smaller one, wouldn't I be better off with a very large black hole? Further, wouldn't this mean I could get deeper in the gravity well which would have a greater relativistic effect? Lastly, if I found a black hole that was rotating, wouldn't the centripetal forces involved mean I could safely get even closer to it? I know this is pretty long. I appreciate anyone who spends any time answering these hypothetical questions.
