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