  • One of the biggest reasons for colonizing other worlds is to ensure we don't die with our own sun, but even those alien suns we might travel to will die one day. And yet, our image of stars living than erupting spectacular as a red giant or supernova, present a somewhat false impression, as those stellar remnants often last far longer than the stars which bore them. Could civilizations survive around these dead stars? Could they even outlast the End of the Universe, as the last stars fade away?

    I think the popularity of this series speaks to one of the best things about your channel: your optimism. We hear a lot about the universe's eventual demise, and that's a painful and scary thing to think about - it can make life feel hopeless and futile. Your videos help make sense of things and let us understand our options.

    Isaac, I'm going to be 100% honest here. Your channel is one of the only truly enlightening,100% family friendly,drama free,well meaning channels I've ever subbed too. In an age where every other channel is flipping out about politics, youtube drama, culture clashes, pessimistic news,and vapid content centered around materialistic and childish mindsets your channel stands as a beacon of light on youtube, an example of what the internet's entertainment options *should be* ,it stands as proof that a single person with enough gumption, a little book learning, and a love for reading can add to humanity without taking anything precious from society or adding anything corrosive.
    Thank you Isaac Arthur! Your work is invaluable!

      We could of course maintain the Sun until close to the end of time by star lifting, removing heavy elements and providing hydrogen, as a tribute to our original home.
      No reason to move the earth when we can just maintain the sun as is.

      I dunno. I don't think he's described a Quasar Shkadov yet. He has talked about black hole engines and harvesting energy from the accretion discs, though, so I might have blanked on that one. Plus, I've not seen every episode.
      I suspect it's a really lossy, and therefore lousy, way to use an absurd amount of matter though.

    The topics you discuss are on titanic scales yet you explain them in an approachable and descriptive way. It’s really phenomenal what you are doing. Just putting these videos out and having these ideas spread will maybe inspire and empower individuals to get us the a place where we can colonize our galaxy.
    There is tremendous weight to what you are doing here and I believe it won’t go unnoticed.

    Isaac, I doubt you will see this, but it is worth saying nonetheless. I want to thank you for continuing to make such high-quality and informative videos. I am a student, and I find myself often working on homework and various assignments with your videos on in the background, and for some reason, they always seem to turn out better when I do. I'd say you have given me an extra point in my GPA, so thank you kindly for that, but also for being an inspiration to commit to putting out the best-quality work I can. Keep up the fantastic work! Ar-Thursdays are some of the best times of every week for me.

      Okay! I'm back from school! I forgot to keep you posted, though it was a pretty smooth day.
      I started in Geography, which is where we watched that film. Then, since the documentary ended 30 minutes early (I guess because it was online and didn't have advertisements it was shorter, and the documentary was expected to be found on TV instead.) so we went ahead to do some more assignments until the bell rang. Lunch time. I ignored food and went straight to visiting with my friends and chatting about D&D. Some hours later school got out. A friend picked me up, we went to my place to set up my mum's FAX (yes, a FAX) Machine.
      Then I remembered that I was supposed to keep you posted on things, and came here to type this thing out.
      The end of time can now proceed!

  • @theCodyReeder
    @theCodyReeder 5 лет назад +14

    3:22 ok I keep hearing this but can anyone explain why we wouldn't be able to see galaxies outside the local group? It doesn't make any sense to me. Like sure we wouldn't be able to see new events and everything would become increasingly red shifted but I cant imagine not being able to see that the other galaxies at all. Doing the math for right now the cosmological event horizon is 13-14 billion light years away but we can see things that are 93 billion light years out.

    • @BlakeShorter
      @BlakeShorter 5 лет назад +7

      It is to do with our universe expanding at an accelerating rate. If you extrapolate that out, eventually (very long time scales) that expansion rate gets so high that the most distant objects are expanded to be outside of the observable horizon.
      Imagine our observable horizon as a light cone. With space expanding faster and faster, this eventually means the furthest objects move away from us at faster than the speed of light, so they would literally move outside our light cone, and no longer be observable.
      Over longer periods of time as more objects move outside our horizon, less and less galaxies will be observable, until at some point it would just be the local gravitational bound group. I guess if you take that idea to its extreme there would be some point in the super far future where no other stars would be observable.
      I have seen it shown really well in graphics before, in PBS Spacetime I think but I can't find the clip.
      This chat is super relevant: ruclips.net/video/DXtWrDjDIGI/видео.html
      Also: en.wikipedia.org/wiki/Cosmological_horizon
      Really depends what happens with the expansion, can it really accelerate forever? Most things have limits so we'll see I suppose.

    • @paulwalsh2344
      @paulwalsh2344 5 лет назад +3

      @ Cody'sLab I have to ask, where did you hear that we can see things 93 billion light years away ? Because we can't. The most distant and therefore earliest objects we can see optically are Quasars which are large primordial galaxies with super massive Black Holes at their centers gorging on the prodigious amounts of hydrogen available in the smaller volume of the early universe. These are from the 13.5-ish billion lightyear range. When we are looking at the Cosmic Microwave Background radiation, we are looking at photons finally released at the re-ionization epoch of the universe where the universe finally became transparent to visual light after the dense opaque plasma of the primordial soup of elementary particles created in the Big Bang. These CMB photons are red-shifted from visual light frequencies down to the microwave end of radio frequencies in the ElectroMagnetic spectrum.
      When we say the universe has a diameter of 93 billion light years, we make that assumption based on not only the radius of the observable universe but added to that the extra distance due to the expansion rate of the universe over that 13.75 billion year history. But objects 14 billion light years away shining away in their corner of the universe have not had time for their photons to reach us and due to the speed limit of light, they NEVER will. BTW, we are not "seeing" the CMB from any hard edge of the univers from where they originated, but are seeing those photons kinda frozen in space due to the expansion of the universe. Kind of like smoke in a room. There may be denser areas of smoke and lighter ones and observing those difference patches and theorizing about what causes them give us some indication of the conditions at the time.

    In the big rip theory, the force of dark energy isn't constant and increases over time. This causes first galaxies to fly apart, then solar systems, then planets, then stars, then atoms, then the atom nuclei. If it keeps increasing, it would start pulling the quarks inside protons and neutrons from each other. Since quarks have to be in pairs, if enough energy is put into pulling the quarks apart, they will just create new pairs. If this is true, wouldn't this cause a runaway effect of quarks "duplicating" until it supersedes the expansion of the universe?

    Hey you fellow SFIAns with your drinks and snacks, I grabbed an entire dinner to eat and see this. :)
    Lovely episode, Isaac. I appreciate the sheer audacity of purposely making stars go supernovae. I really wish there were some way of capturing that energy better. But if we want to bring extra galactic stars to us, we may not have other options. I do agree that if humanity ever got serious about star travel, the stars of atleast our galaxy will soon be snuffed out by our descendants like we might do to wildfires/coal fires.

    At 4:35 you mention 'big rip' when eventually even the atoms get ripped apart. I presume that the big rip, in all its splendor, is a consequence of dark energy doing its thing. What I don't get is how it will be possible for it to rip atoms apart in view of the prevalent agreement that dark energy is constant per unit volume.

    • @paulwalsh2344
      @paulwalsh2344 5 лет назад +1

      @ Jake LaBete Yes, I like like what yer thinkin'
      As I wrote above somewhere, the Big Rip is the bane of my astronomical enthusiasm. Proponents of the Big Rip scenario really have to answer a few questions that indicate that the Big Rip is likely ?
      1. Is the nature of Gravity fully and completely understood by physics ?
      Is the force of gravity, like the other fundamental forces of the universe, mediated by a quantum particle, the Graviton ? What is the mass of a Graviton and the speed of a Graviton ? What is the effect of this speed on the 10 Mega-parsec scale of the large-scale universe where the cosmic expansion is dominant ? What I'm getting at here is, is Dark Energy to gravity, what redshift is to light ?
      2. Have physicists demonstrated that Space-time a fabric that is Rip-able ? The notion of "the fabric of Space-time" is a popular misconception of the lay-person explanations of Einstein's General Relativity view of gravity, that mass distorts or puckers a 2D representation of the space around it, like a bowling ball on a stretchy spandex sheet, but the reality is that mass affects the space around it in all the infinite axes of 3D space. So is space a fabric that is rip-able, or just space... the absence of matter ?
      3. Have physicists the evidence that the Dark Energy that's causing the cosmic expansion that's obvious on the large scale (10 Mega-parsec scale) is also seen in the space, let's say, between our Milky Way and the Andromeda Galaxy or the other members of the local group ? Own Milky Way ? Our Solar system ? Is there evidence that Dark Energy affects space at the atomic or sub-atomic scale, between the Protons, Neutrons and Electrons or the Quarks so that Dark Energy will eventually rip apart matter at it's fundamental scale ?
      These are the questions that seriously and honestly have to be asked to put in perspective the sensational and apocalyptic notion of the Big Rip scenario.
      The fact that we observe effects that have no valid explanation shows the limitation of our understanding of Physics yet.

    Isaac, would you consider doing an episode dedicated to the Big Rip only? The way you explore topics in depth makes me think that finally someone will shed some light about what happens after the macro level rip. When ripping occurs on subatomic level. After all we can't expect everything there is in the universe will turn into nothing. There still will be remains from the current structure, therefore time will still exist. Maybe Big Rip ensures the universe is truly eternal... would love if you develop the subject.

    One thing bothers me when moving star systems and galaxies is discussed. Both of these have a lot of other stuff besides the stars themselves. It seems to me if you moved a star with a Shkadov thruster, you might lose the star's Oort cloud, if not other stuff closer in. With galaxies, it's even worse, because they have a dark matter halo that makes up the vast majority of the galaxy's mass, and keeps the stars in orbit at greater distances than would be possible without it. On the other hand, by the time we want to do this, we might have figured out what dark matter is and be able to control it directly.
