I mean, it would be nice of them to do so, but it is not that big of a deal. The extra-cosmic Blockbuster has a universe-rewinding machine, so if they get a universe back and they see that it is not rewound, they just pop it into the rewinder and it comes out queued up for the Big Bang. Well, I mean, most of them have previews at the very beginning before the Big Bang, but no one really watches those.

If white holes exist then they could reverse the entropy of the universe. In fact the heat death of this universe could be this universe falling into a multidimensional infinite black hole and later being spewed out by another multidimensional infinite white hole thus causing another big bang. This big bang might not be the first. No one knows if this is the first iteration of the universe. I have a hunch it is the 6th one. In the Matrix we trust.

In comparison, it took 11 years to make the Blu-ray after blue LED lasers were invented. Even though we already had led lasers and blue lasers. Not to mention the fact that all a Blu-ray is, is a DVD with a different laser and programming 11 years. NASA is absolutely kicking ass.

Though seeing as, as far as I know, those aren't real types anyway, I guess it would just be a type 3.

@garethdean6382

No, such teleportations tend to be limited by horizons, given the expansion of space only a small fraction of the universe's matter can suddenly clump. And given how smaller clumps are more likely we'd expect 'big bangs' to be vanishingly rare. Most often you'd just get a tiny dust grain or puff of gas forming. Maybe an asteroid now and then. A planet nearly never and a star even less often. Eventually everything would be so far away nothing could teleport to anything else.

Gareth Dean what does “tend to be limited by horizons” mean? Are they limited always, or in some cases, like not for paired particles e. g. or never (but it looks like they are because we havent observed the opposite yet)?

The fact that the solar life of the universe has 99% left of its total lifetime makes the universe seem so full of potential. I wonder how we humans would have felt if we instead found out there's only 1% of the solar lifetime left. This would definitely have some significant existential impact on our collective psyches

There's a feeling I remember when watching the stars in total darkness in Wyoming as a kid, seeing the Milky Way, the planets, satellites, and meteors, that I can't see now that I live with too much light pollution. I felt small but connected. I've experienced a related feeling looking from a mountain top in the evening, seeing lights of small towns 30 miles away. And I remember how I felt when I saw the total solar eclipse last year, when my sense of the sun and moon and their locations, and connection to how we define time, seemed suddenly clearly tangible and "physical", in a way it rarely does. The sun and moon are normally just a backdrop to whatever I'm paying attention to here on earth at the moment, but during the eclipse it all felt like one big connected machine.

We're already at a point where we are not fully dependent on stars to survive. We can replicate our living conditions fairly easy. The only real reason we don't already have hotels and apartments in orbit are because of how prohibitively expensive such efforts are with our economy and current level of technology. The main problem would be harvesting enough solid matter to create a sealed environment and capturing enough energy to keep that environment functional. Still leads toward the same end game though, eventually all that energy is converted to heat and heat death sets in.

As for the big crunch, it's seeming unlikely that it'll ever happen. Dark energy is prevailing over matter, and so infinite expansion seems to be inevitable.

Danielle Spargo Sorry I should have written "telescopes" as obviously just seeing light doesn't work... I meant detecting other things that we can't yet "see".. or just generally better understand and bringing theories together. Just because string theory is at the forefront, doesn't mean it's the absolute winner. There are endless new things to discover... creating more questions than are answered... and whatever we "know" now can change dramatically with the next discovery waiting for us around the corner. I hate to compare it to religion but in a way, we also have to also have faith in our current research that it's all correct... but compared to religion, scientists are constantly looking to find the real truth (understanding) therefore what is "truth" is constantly in flux. I'm just waiting until the next Einstein comes along, showing us some elegant explanation for merging currently scattered theories. Maybe he/she is already out there, we just have to wait for them to stop working at the patent office :P

I absolutely LOVE this series! 😀 Matt, you're a star.

5:12 That's so cool to think about! A very similar thing happens on a much smaller scale with the formation of stars. When a gas cloud collapses to form a star, the outer regions of the cloud are expelled from the system. In both cases, this is inevitable due to the second law of thermodynamics. A star and a tightly bound galactic core are both much lower entropy that the original gas cloud/galaxy they formed from. Thus, a large portion of the gas/stars must be ejected out of the system in a very diffuse high entropy state in order for entropy to increase overall. The same thing also happened on a universal scale. The large-scale galactic structure of the universe is lower entropy than the universe's matter after the big bang which it formed from. Thus, in order to have increasing entropy overall, the formation of these structures must have dispelled lots of ultra diffuse high entropy gas.

Thank you so much for making these videos! It’s unmatched by anything else. Challenging and not dumbed down physics. Love it!

We are all cosmic babies, or perhaps I should say embryos.. I've always been fascinated about the 'Deep Future'. Kinda took me by surprise when I got the announcement of this video. Finally a Spacetime video about this intriguing topic! And of all the vids I've already seen, this one nails it!

Wikipedia posted an article all about this timeline of the future of the universe on its Facebook page a few days ago. Thanks for making a video about these events! It's super interesting!

If black holes can live to be a million googol years old, does that mean we are in the very early stage of the universe, relatively speaking? Seeing as it's only 14 billion years old... Jeez, we're babies.

This is all "relative" to us biological, atomically based lifeforms. -> The universe had many "ages" in the first fractions of a second of existence after the begining of the bigbang [some of them with truly "catastrofical events" like the separations of the fundamental forces]. While we can not conceive any kind of "life" in those conditions; the basic concept of increasing entropy was already there...

this would be the question for a 'static frame of refference' which is believed to not exist. there is no part of the universe that is the one real frame of refference BUT you could use the cosmic micorwave radiation, which gives a 'screenshot' of the universe at some point after the big bang. If you want, you could use that to mesure your relative speed to it and by that means you could slow down to zero speed but thats just making up a frame of refference at the end of the day

The Cosmic Microwave Background (CMB) radiation pattern is just an ilusion. Every point of the universe has one that is NOT exactly the same [since the "shape" of intensity and location of each of its "points" is a bit different]. -> Because of quantum fluctuations, there was NEVER a single "instant" since the begining of the universe where everything was EXACTLY the same [for spacetime to exist and flow, quantum proceses must also happen]. At best, you can gather data from different points through the Virgo Supercluster of galaxies about the CMB (from those different "centers of the universe") through the age of the stars to get a nice big chunk of the "full 3D Map" of the density of the young universe (less than 1 millon years old); by taking account how the CMB changes as the cosmic horizon expands [it will tend to look the same on each point]. -> This would NOT be a comprehensive description of the origin of the universe [for that we would need some way to measure the "Cosmic Neutrino Background" radiation, assuming it is even possible]; but for any PRACTICAL reasons it will be "as good as it gets" for a "fixed frame of reference".

But it would never be as expriments show that the rate of expansion is increasing with time because of some unknown energy and the energy is continuously increasing that tends to expand the space faster and this cycle goes on So at last a time would come when the expansion would be so fast that even atomic particles will be torn apart at after that everything is over..

It gets REALLY strange... When Dark Energy (whatever it is) starts "pulling out" quarks with more "force" that the equivalent mass/energy that makes them... they do not "split" but instead REPLICATE. -> The stronger/faster you pull them apart, they replicate EVEN FASTER [no spacetime gets in between them]. At the end, matter wins by filling everything as an endless growing sphere going faster-than-light [but from the "relative point of view" of each quark, it is "alone" in an endless, eternally silent void; unaware that is making infinite copies of itself in all directions (more than a "single infinite"), all the time].

The annoying thing about these timetables (the ONLY annoying thing) is the fact that you end up having to put your scientific notation into scientific notation into scientific notation

One of your 5 best videos for sure, and probably the best and most comprehensive in its topic. There is another possibility within the big rip which I got from watching another video: Once small enough particles begin to rip, more of their kind are created from the energy that separated them, causing a renewal/continuation of inflation/the big bang. This allows an always expanding version of cyclic creation.

But why would a big rip jump-start the universe? Or rather, why would it jump-start the universe any better than heat death? If a big bang is born out of some freak quantum event (a big if), then it might just as well start in a universe deep in heat death, as it can in a universe ripped to shreds by dark energy. Or am I missing something here?

Big rip...the idea I heard and found pretty fascinating is that if the force that is expanding the universe continues to grow, it may get to a point where it expands space itself at such a rate that it creates an actual vacuum, and that vacuum may be the start of a new universe. Wish I could find the video I saw it on...

That's vacuum decay you're talking about I think. In the big rip scenario, dark energy tear spacetime itself to shred, and there's nothing left. Time itself stop making sense.

"We will enter the degenerate age, not to be confused with the 1970s." Lmao

There might be a marvellous symmetry between the universe’s birth (Planck’s age) and its death (Kelvin’s), filled with spellbinding mathematical harmony. Various Quantum Thermodynamics model, based on second law’s purely statistical nature, predict the nonzero possibility of a new universe arising from fluctuations or “random” phenomena over a very vast amount of time, if thermodynamic equilibrium is not achieved. But in either case, I still love the parallel between the initial singularity, when time “was not”, and the final state, when time “means not”.

I love how he is so definitive, yet we don't truly know. The current evidence suggests the universe is expanding, but we don't know for certain if it will keep expanding or not, or we could be missing something important. We have a decent idea, but we could be totally wrong. Until we find TOE, I'm going to remain cautiously optimistic that the universe is on an infinite cycle and I will live this exact life again sometime in the future.

You will live this life again, all things must reoccur in an infinite amount of time. At some point, time and space will be in the same state as the big bang was. Time will not exist when nothing can happen. So there will be a long spance of nothingness... But someday the universe will get tired of being "nothing". Just as it did in the beginning. All the evidence for this is the fact that were all here now. Why aren't we already gone? Maybe that's because we will never be "gone". We have done everything it is to do over and over and just don't know it. And will still to infinity.

Michael & nonam are both confusing "infinite" with "complete"; to say "this set MUST have every possible combination in it" means it has to be complete. The set of all even numbers is infinite, but is missing all odd numbers, for example. There'll be a _probability_ that same-exact-configuration recurs, but it'll never be certain. --Dave, many things COULD recur. nothing says everything WILL.

I personally agree that heat death currently seems to be the most likely outcome of our universe, but it is worth noting that this is just one of multiple theories. (edited because of a typo)

keviscool It’s true that we don’t understand Dark energy completely but based on what we know dark energy’s energy density is about 10^-8 ergs/cm^3. Meaning that the universe’s expansion up until about 9 billion years ago because the density of matter and dark matter diluted enough that dark energy took over accelerating the universe’s expansion.
