Philosophical implications of an infinite universe? How do we cope with infinity?

It is often remarked that nothing we do now will matter in a million years. But if that is true, then by the same token, nothing that will be the case in a million years matters now. In particular, it does not matter now that in a million years nothing we do now will matter. Moreover, even if what we did now were going to matter in a million years, how could that keep our present concerns from being absurd? If their mattering now is not enough to accomplish that, how would it help if they mattered a million years from now? Whether what we do now will matter in a million years could make the crucial difference only if its mattering in a million years depended on its mattering, period. But then to deny that whatever happens now will matter in a million years is to beg the question against its mattering, period; for in that sense one cannot know that it will not matter in a million years whether (for example) someone now is happy or miserable, without knowing that it does not matter, period. What we say to convey the absurdity of our lives often has to do with space or time: we are tiny specks in the infinite vastness of the universe; our lives are mere instants even on a geological time scale, let alone a cosmic one; we will all be dead any minute. But of course none of these evident facts can be what makes life absurd, if it is absurd. For suppose we lived forever; would not a life that is absurd if it lasts seventy years be infinitely absurd if it lasted through eternity? And if our lives are absurd given our present size, why would they be any less absurd if we filled the universe (either because we were larger or because the universe was smaller)? Reflection on our minuteness and brevity appears to be intimately connected with the sense that life is meaningless; but it is not clear what the connection is.
