Einstein's Theory Of General Relativity :

Sir Isaac Newton explained the impact of gravity but did not explain how it works.

Many years later. In 1915 , Albert Einstein published his theory of General Relativity and explains ‘Gravity’ as a distortion of space caused by presence of matter or energy.

In Einstein’s mathematics, space has 3 dimensions, and the 4th dimension is time. Space time can be thought of as a grid or fabric, The presence of mass distorts this space time fabric.

Do you know ?

Black holes were first identified in Einstein’s theory of general Relativity.Black holes distorts these space time so much that even light can not escape from it and even time behaves in unexpected ways.
