Einstein’s Theory of General Relativity originally came to him in 1907 while he was sitting in a chair in the patent office in Bern. Lost in thought, he began wondering what it would be like to drop a ball while falling off the side of a building (James Overdunn, Stanford Edu) Granting all this, he realized that the person who was falling would not be able to detect the effect of gravity on the ball whereas an observer could. Hence, he figured out the principle of Equivalence, that gravity pulling in one direction is completely equivalent to the acceleration in the opposite direction. Nevertheless, his work was only seen 8 years later when he published his theory in 1915. Another key factor in Einstein’s theory of general relativity is…show more content…
These sensitive gyroscopes orientations were being monitored in conjunction to a guide star. As a result, this mission was deemed a success and backed up both of the two theories they were testing. Importance Einstein’s theories of Relativity were thought to be one of the most important discoveries in the early 20th century. They led to many different discoveries that would have taken decades more to discover without it, who knows some might not have even been discovered yet today. Some of the discoveries that his theories led to are: Edward Hubble’s observations that the stars and galaxies move and that our universe is constantly changing and expanding (1924). Hubble based his calculations on Einstein’s General theory of relativity. What’s funny is that Einstein actually rejected Hubble’s theory to support his own theory that the universe was static but had to in the end support and agree with Hubble’s theories since they were based on his own theories!(Burgess,Discovery) Alexander Friedmann in 1922 used Einstein’s equations of relativity to figure out the approximate age of the universe at over 10 billion years old (we have now figured out it’s around 13 billion years old, but he was close) known as “The Big Bang Theory”. The theories of relativity also led to the discovery of the existence of black holes and gravitational waves, which we are still researching today. (Burgess,Discovery) The theories also led to gravitational lensing and reverse
