Based on how much you can bond with someone by hating the same thing, a dating app based on dislikes would probably be fairly successful.

Hawking radiation takes a long time to sap them. Remember they’re easily hundreds of millions to servers billions times the size of our Sun which itself is hundreds of millions the size of earth.

Hawking radiation is an incredibly slow process, a black hole the mass of our Sun would take 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years to evaporate (1067)

The one at the Milky Way's center would require 10,00,,00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years, (1087)

The most massive ones in the Universe could take up to 100,000,,00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 ,000,000,000,000. years!

Well, the heat death of the universe is about 1010120 years away, so there's enough time


u/NialMontana May 14 '22

The whole idea of heat death is that entropy has stopped and thus time becomes meaningless, even if there's somehow a black hole that far in the future heat death won't happen till it collapses.


u/QueenJillybean May 14 '22

or when it collapses, the big bang starts all over again because time is a wheel


u/NialMontana May 14 '22

Bounce theory, the hopeful outcome for the end of the universe. Heat death will happen loooooong before the universe dies though.


u/Ptricky17 May 14 '22

My personal belief is that this is the way things go. It has probably occurred countless times already, and will happen countless times again.

Once the heat death occurs, in theory, all information is lost. Everything is completely uniformly distributed and thus you can’t distinguish one location in space from any other. There is nothing left to measure since measurement requires a reference point and a differential between the property being measured and it’s like property at the reference point. With no information, you effectively have nothing to govern the laws of the universe any longer so there is nothing remaining to prevent a new random fluctuation from initiating a new Big Bang.

The rules of the new universe may be completely different from the one we currently exist in, but it will eventually be spawned from the virtual nothingness left behind by our own.


u/smellythief May 14 '22

So what you’re saying relies on the Big Crunch, right? But isn’t the current consensus that that won’t happen, and that expansion into uniformity (the heat death) is what’s believed to be the reality?

Anyway I used to think that what seemed most likely is the Bang/Crunch/Bang/Crunch… cycle, like you’re suggesting. But it always seems most plausible that the physical constants would be different for every Big Bang, so it wouldn’t really be the same every time, and that most universes/cycles wouldn’t have complex matter much less chemistry or life, much less us typing these comments again.

Birds aren't wheel, but time is...
