 Dark energy is not only terribly important for astronomy, it's the central problem for physics. It's been the bone in our throat for a long time.”

Relativity, general

"Space tells mass how to move" while "mass tells space how to curve" -- J.A. Wheeler. Einstein created this model, which describes gravity as a curvature in space-time, which is the four-dimensional fabric of our universe. His theory is the best model for gravity so far, and has been confirmed in experiments and observations. According to the theory, regardless of one's point of view (as measured by speed and direction), physical law and the speed of light are unchanged. This implies that measurements made in time and space are not absolute, but relative to your particular point of view or reference frame. General relativity led to concepts and theories such as black holes, parallel universes, worm holes, and space-time.
