Short answer is that life as we know it could be sustained by the universe for a very long time -- even longer than the universe has existed so far -- but not forever.
The reality is that we just don't know. Our observations (and projections) are based on what has happened, and that might change over the billions of years. Our definition of what is "alive" will certainly change over time.
