I like quantum sciences and find this thread interesting...
If we think in terms of past/future events, consider this:
If you are walking down a road and you can see it in the distance ahead of you, it means that it is there already in the future and it's just waiting for you to step by step catch up to it.
When I was small, I used to contemplate this example while walking down a road, and I also wondered what "nothingnes" would be like. It's color, temperature, wet or dry, would there be infact, any matter at all, would there be a vacuum affect etc.?
I think that as time is a man made concept, the natural oeder of events and yes as mentioned above, "cause and effect", are really what will decide the end of the Universe.
I also tend not to believe in evolution or Adam and Eve, but rather that there are many many universes, many forms of life out there, that the universe itself has an actual orbit with which all included in it (them), evolves throughout that orbit as an evolution towards and away from higher conciousness. I believe that we are going towards evolution of higher awareness of conciousness and in time, (not sure how long), but we will be at a point of enlightnement with our inner technology as well as our outer technological advancments. When I say inner technology, I am reffering to our brains. It's my belief that our brains (organic computers) will evolve so that we can harness greater gifts and perhaps harness energy and have the ability of telepathy, telekeisis (spelling, lol), and perhaps astro travel as well among other gifts that we possess the ability to have now, but not the awareness with which to tap into it yet. We are not ready yet.
Sorry if I tangented out a bit, but I felt it was sort of interconnected. I do believe that we will have the opportunity to reach enlightenment first, before the end of the universe as we know it...
