What is general relativity?

  1. The general gravitational & centrifugal attractions between massive heavenly bodies like galaxy clusters.

  2. The equation that proves the Cosmological Constant put forth by Einstein.

  3. Einstein's theory based on the idea that the laws of science should be same for all observers, no matter how they are moving. It explains the force of gravity in terms of the curvature of a 4 dimensional space-time.

  4. None of the above

Explanation

General relativity, proposed by Einstein in 1915, describes gravity not as a force but as the curvature of spacetime caused by mass and energy. The theory states that the laws of physics are the same for all observers regardless of their motion. It explains gravitational phenomena as objects following the curved geometry of 4-dimensional spacetime. This framework successfully predicts black holes, gravitational lensing, and the expanding universe.
