IT is often thought that the theory of curved space-time (general relativity theory) accounts for gravitation but does not account for the electromagnetic phenomena. This is not so.

and proposed new concepts of space and time. He then spent 10 years trying to include acceleration in the theory, finally publishing his theory of general relativity in 1915. This determined that ...
