Stephen Hawking's most famous prediction could mean that everything in the universe is doomed to evaporate, new study says

https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.130.221502, quite interesting :)

Space.com reported, "What the researchers' theory means in reality isn't clear. Possibly, as the matter that makes up stars, neutron stars, and planets ages, it will eventually undergo an energy transition into a completely new ultralow energy state. This might be enough to eventually collapse all matter into black holes, which could continue to slowly drip out light until they too disappear without a trace. Unfortunately (or fortunately, depending on any misgivings you may have about evaporating), all of this is just speculation awaiting confirmation. To figure out if it's a true prediction of our universe's eventual fate, physicists will need to spot some Hawking radiation being produced around gravitationally dense objects — both around black holes and planets, stars, or neutron stars. If everything is destined to disappear in a flash of cool light, there should be plenty of places to look."

So the expanding universe potentially ends in a *black hole* that evaporates, thus no other beginning after this fate :) No infinite universe or cyclic universe(s) here :) So, the Big Bang violates conservation of energy law at the BB moment of creation (before Planck time), as the universe expands, eventually everything decays into a black hole that evaporates :)
