Which of the following statements best describes current understanding of the eventual fate of the universe?
A) Although the accelerating expansion suggests that the universe will continue to expand forever, it is possible that future discoveries will indicate a different fate. B) The universe will continue to expand forever, because only gravity could reverse the expansion, and it is not strong enough to do so. C) The acceleration of the expansion will eventually lead to a Big Rip that will break all matter apart. D) The universe will gradually decay as it continues to expand, with protons eventually decaying and black holes ultimately evaporating, leaving the universe cold and dark.
