The most common view by astronomers and physicists is that if the Universe
is flat, it will keep on expanding forever. Eventually, life will go extinct
because there will never be any new star formation after a long while, and
the energy sources that remain will decay into lower and lower levels.
Typically this is called the "cold death" viewpoint. Flatness and expansion
is not the traditional Steady State Universe, where life may continue
forever. Nor is it the Heat Death of a rebounding Universe, which also would
bring annihilation.
