It came to be accepted when everybody who had the equipment and the ability
began to measure it and found that it's true. It's been observed thousands of
times in the past hundred years or so. And at places like the Livermore National
Laboratory, the Stanford Linear Accelerator, the Argonne National Laboratory,
the CERN, and the LHC, it's observed every day.
einstein came up with the general theory of relativity
albert Einstein
While Einstein was a great scientist, who accomplished much, he is probably most famous for his theory of relativity. ( E=MC2 energy equals mass times light squared)
come at me bru
he took a big dump
Einstein's theories were General and Special Relativity. Hawking put forward a theory combining relativity with quantum mechanics.
Albert Einstein introduced the "Matter Energy Equivalent" a part of "[General]Theory of Relativity" on September 27th 1905; it was from this work that the famous E=MC2 is taken.
Albert Einstein did not have any inventions. He did come up with some revolutionary theory's about space and time and his theory's helped in the development of the atomic bomb.
1 year, i think
Currently, the most accepted theory is that it resulted from a crash between a large planetoid (or "protoplanet") and Earth.
He came up with it because it is a universal truth, which is what all scientists strive to discover.
A scientific theory is an extensively tested hypothesis that is accepted as the best answer we can come up with, since nobody has been able to prove it wrong yet.
