Looking Into The Future

Modern cosmology faces numerous challenges. One of the biggest is to predict the ultimate fate of the universe.

This acceleration is due to a mysterious force called "dark energy" that may be stretching space itself. Just what dark energy is, and whether it can be incorporated into our current models of the universe, remains to be seen.
