ALBERT EINSTEIN'S THEORY OF RELATIVITY (1905 CE/AD)🔗

This comprises of two interrelated theories: Special Relativity Theory = "matter and energy are interchangeable"; General Relativity Theory = "space and time are linked for objects that are moving at a consistent speed in a straight line". The basic idea is captured in a simple equation E = mc2, where E is energy; m is mass; and c is speed of light. many scientists feel Einstein's theory is incomplete, as it fails to fully explain the physical phenomena of modified gravity in dark matter (particles invisible to light but endowed with gravity), in black holes and in the motion of stars and gas in spiraling galaxies and galaxy clusters.
