Comment on big facts
cynar@lemmy.world 1 week agoOur best ideas on the big bang put the universe as huge, but finite in space. (Way bigger than the observable universe) The question is time. If time is infinite then Boltzmann brains win.
Matter has a finite life, energy differentials run out. Stars run out of fuel. Black holes evaporate. Even protons eventually fall apart to energy. Then there is endless emptiness.
That emptiness would be finite in space, but infinite in time. Without that last boundary, weird things happen to maths.

If you appeal to heat death then you cannot say brains pop back into existence either because “matter has a finite life,” and so it is self-defeating. If brains can pop back into existence due to random fluctuations then surely planets and stars could as well given enough time.

The energy to spontaneously create a planet is vastly more than a brain. Then again, with the weird maths of infinities, it might play out.
Though to recreate the full illusion would require something closer to the big bang itself.
It’s well into the “here he dragons” realms of science however. Speculating well beyond reliable evidence.
