Question

What is the einstein general theory of relativity

Answer 1

Einstein proposed that objects such as the sun and the Earth change this geometry. In the presence of matter and energy it can evolve, stretch and warp, forming ridges, mountains and valleys that cause bodies moving through it to zigzag and curve. So although Earth appears to be pulled towards the sun by gravity, there is no such force. It is simply the geometry of space-time around the sun telling Earth how to move. 

This is a short information about Einstein relativity theorem

It could be written as e=mc^2

hope it helps u

Answer 2

$e = mc ^{2}$
