Dark Energy Expands the Universe

It is believed that after the Big Bang, the universe originally decelerated in its expansion, but then 'changed gears' and began to accelerate. The unknown force causing this recent acceleration is dubbed the 'Dark Energy.' This visualization flies through a series of galaxy clusters, the largerst gravitationally-bound objects in the Universe.
