Cosmological antigravity
Article Abstract:
Albert Einstein's theory of a cosmological constant was proposed so that the universe would have a repulsive force, a form of anti-gravity in which the universe would expand eternally. Even though Einstein eventually discarded his theory, it is being used to explain the acceleration of universe's expansion.

From slowdown to speedup
Article Abstract:
The emission of fainter light from the supernovae was an indication that they traveled a greater distance than expected. This led to the conclusion that the universe is actually speeding up, not slowing down due to the presence of a dark energy form.
