Reading about how, over time, the volume of a black hole seems to grow infinitely makes me immediately jump to an obvious connection:
The universe as a whole is ALSO a system that appears to grow infinitely.
I mean, there have been many conjectures that a black hole could contain a new universe, and that the creation of a black hole also creates a new universe. This would seem to hint at another potential connection.
That said...I'm really not a physicist, so maybe that connection is at best a hook for a science fiction story. But it surprises me that the article didn't even mention the parallel.
- pdonis 3y ago> over time, the volume of a black hole seems to grow infinitely Unfortunately, the article fails to note that this is a speculative hypothesis with which not all physicists agree. It's not an established fact. It's not even an established theoretical prediction.
- Freestyler_3 3y agoI like that idea, a bubble has small bubbles inside. All of them growing, but one inside it is growing more, and it "eats" the others until it consumes the bubble it is in, and then it pops and all matter starts moving from center outwards. Now we need to find some way to prove this is real.
- hinkley 3y agoI'd be willing to put $100 on longbets to say our universe is inside a singularity, but I doubt anyone who remembers I existed will still be alive when we figure it out.
- ben_w 3y agoYou can't be inside a singularity because that's a point, but we are inside (surrounded on all sides by) an event horizon.
- boringuser2 3y agoWhat proof exists for this hypothesis?
- vermilingua 3y agoThe hypothesis that we are surrounded by an event horizon? That's not a hypothesis, it's a logical conclusion. The observable universe has a boundary beyond which the expansion of space is faster than the speed of light; therefore light cannot reach us, which is the (loose) definition of an event horizon.
- rocqua 3y agoIn other words, the evidence for that is the evidence of the exponential(ish) expansion of space.
- hinkley 3y agoMy other long bet is that 100 years from now we'll still be telling people, "I bet you're fun at parties." And if we're going to 'well achtually', we don't know what happens inside of an event horizon. If time stops due to the infinite curvature, does the singularity ever form, or does it just collapse in on itself for eternity?
- rocqua 3y agoIt is consistent to say that anyone at that point all of a sudden gets an extra "coordinate system" they can interact with, but they can never leave the point in the outer coordinate system. That would be 'every singularity contains a new universe'. It's not a very scientific theory, since you cannot report back after attempting to test its predictions. Though the predictions can be tested empirically!
- moffkalast 3y agoYou best bet some future physicist doesn't also figure out how to reverse entropy, or they'll be back to collect on that bet.
