The short answer is, you can't. There are all sorts of fancy tricks you can
use to keep yourself going for a very long time, but you can't reverse
entropy. The energy density of the universe declines until it becomes
impossible to build any sort of organized system. To survive indefinitely
you have to change the laws of physics, move to another universe, or
otherwise avoid the issue.
Fortunately, it doesn't matter. The entire big bang/inflation model has
been under increasing strain for the last two decades, as it becomes
increasingly difficult to reconcile its predictions with actual
observations. A lot of the recent 'fine tuning' of the model looks a lot
like medieval astronomers adding epicycles to epicycles. Unless a lot of
recent observations turn out to be wrong, we are going to end up with a new
model that gives very different predictions about these issues.
The latest issue of Scientific American has some good articles on this whole
topic.
