Einstein’s Theory of Relativity Explained (Infographic)

The theories of relativity by Albert Einstein revolutionized how the world thinks about space, time, mass, energy and gravity. Prior to Einstein, the laws of Isaac Newton were used to understand the physics of motion. In 1687, Newton wrote that gravity affects everything in the universe. The same force of gravity that pulled an apple down from a tree kept the Earth in motion around the sun.

PS. Nice infographic but the speed of light (299338 kps)  is wrong. The speed of light is 299792.458 kilometers per second.
