What if?

But what if the universe ceased to exist in billions of years?

The Universe is infinite, it cannot cease to exist. It has no start and no end. The Big Bang theory saying that the Universe appeared from an infinitely dense point is both false and doesn't make any sense. Something cannot appear out of nothingness, in nothingness, when there was no time, because this is the model the theory proposes, an infinitely dense point of matter, where there was no matter and space and time. This is why I consider it doesn't make any sense. As crazy as it might sound, if the Universe is infinite in space, meaning it has no bondaries, then is infinite in time as well, meaning that it never started.

But the `Universe` is simply void space so it shouldn't be surprising that this infinite void space has no beginning, what is possible to happen though is that galaxies can be destroyed, for example if they collide with other galaxies, that is possible to happen in billions of years. But in this case, what if civilizations, like the ones of the Gods, are advanced enough to prevent this? I don't know what to say here. For us humans is something we can only imagine about at this moment of time, but definitely the Universe cannot disappear because literal void space cannot be removed.

Life is a fight, even for our Gods.
