Time is a tricky thing to build a philosophic theory upon.
It's a depressing as well as liberating idea, since this theory puts all responsibility on our shoulders. Definitely more depressing than liberating, if you look at the findings in neuroscience that Bakker likes to bring up - that we can't really change anything about our lives, since our "free choices" are the results of unconscious processes and not free at all. We're a part of nature, not immaterial minds outside of it. So, if you take this together with Nietzsche's theory on infinity, the obvious conclusion is "you're doomed to relive the same experiences and thoughts for all time, not even death is an escape, and there's nothing you can do about it."
(To use myself as an example - I've been through several drug addictions and depressions in my life. Some of them medical, some of them the "existential depression" variety that I'm feeling atm. So, to me at least, the idea of eternally re-living this life over and over isn't exactly a happy thought.)
I always seem to think about a lung or a heart when I think of the universe (omniverse) being infinite. I generally don't make it past sheer existential horror to sustained depression when I happen upon with right mix of thoughts like these.
And I apologize now because I know that reading or hearing optimist perspectives makes me want to punch people in their faces when I'm in a shitty mood...
I read your post and I know the kind of mental path I've traveled to gain my personal perspective so I think that if by some miracle I'm still doing this for the "first" time or I can influence the passage of events I want to do whatever I can to make the rest of my eternal recurrence different from the life that's been lived so far (not that it's all been bad but I have change to affect).
Big bang or not, if the universe is truly infinite there would be an unlimited number of "Daniel Christopher Martin's" writing an infinite number of various posts on this very website. There would also be and infinite amount of "Daniel Christopher Martin's" doing an infinite amount of anything else as well... What can you possibly do with an existence like that which could be considered stand up performance?
Well, in that omniverse there's only one GJ being the best possible of all GJs. And it's either you... or it's not

.
Actually, io9 (I believe) posted or reposted a really cool (by cool, I did mean horrifically terrifying) possible experiment to test this... you'd be Jet Li in
One without all the intra-omniverse martial arts. [EDIT:
Quantum Suicide: How to Prove the Multiverse Exists, in the Most Violent Way Possible.]
Now, if we were to live this life over and over again, that could be a different story. You would have an innumerable amount of chances to shape your existence into a "perfect life".
Due to the fact that I don't believe in an afterlife, I don't think anyone can live a "perfect life". No matter how many chances you had the end result would be the same, death and oblivion.
Even subjectively ideal, I think Auriga is suggesting that you write the book of your life once and then read it over and over for eternity.
That brings me to my current philosophy, you only live once with no rewards or punishments after. Live however the fuck you want to.
I would simply suggest that most people have a sense that the spark of life is limited to Earth. I would ask that we all tend this place and the people who stay behind and come after (especially if it's possibly us again) for the "better."
I think it's an interesting idea. Not much more than that.
I'm also a believer in Block Universe Theory. I think everything was always going to happen and already has happened. That doesn't necessarily mean that we have no free will (though I kind of doubt we do). But I do think that reality/existence/the uni and/or omniverse is timeless. It is One Eternal Thing. It always has been, always was, and always will be. It also has infinite variation...because the concept of Infinity exists, it means Infinity does exist. Thus, reality and its variations (the Omniverse).
The One Thing could be contracting? Or there could be flow to it, inside/outside it. Certain fractals could touch each other for short times in the crossing of space and time.
In regard to the conditions that allow time as we know it to exist, I don't think they will always be sustained.
I don't really buy it.
Agreed, purely from the perspective of psychology. We don't unilaterally perceive time the same. It would seem the most rigorous explanation for time then must come from the mathematical languages, not linguistic philosophics bound by the vocal chords of us humans.
