You know that this is not proven right? Or rather, not even a "theory" in the physics sense, there are multiple competing hipothesis, none of them have enough evidence for us to be certain the universe will end... In some ideas the university does end, but in big crunch, or big rip, in others it just starts anew, in others humans spawn new universes, and so on...

There are a lot of competing theories of how the universe will end, but pretty much all mainstream cosmology admits that it will end. Very few cosmological models say otherwise. However, even then I contend that eternity is just another kind of ending. Given an infinite time, everything that can happen will, and therefore it will also repeat. That means that every decision we make will be made again infinitely, every path followed an infinite number of times, always eventually returning back around again, and ultimately the outcome will still be the same. So you see, under cosmologies of eternity, we just exist in a stasis of infinity and our decisions will not change that. Under cosmologies where the universe ends our decisions will not change that either. Does this mean that nothing we do matters?

  "but pretty much all mainstream cosmology admits that it will end." By using "admits" you mean they accept your point of view, even if they do not want to? Thats a bit telling about your worldview. And have you ever considered, that cosmology can only make relative observations and speculations? In other words, if our whole universe is just a small part of a bigger universe, how could we tell for sure, if all we can observe is within those borders? Also, how likely is it, that out of eternal nothing someday came a whole universe which wents back to nothing forever? Sounds more like religion than science.

      I know. But in this context it did sound like the other explanation to me. (Probably not aware by you at the time of writing it)
