Einstein's theories have been proven correct through experimentation from "summary" of Albert Einstein by Walter Isaacson
Walter Isaacson delves into the realm of Einstein's theories and the validation they received through experimentation. Einstein's theory of relativity, which includes the ideas of special and general relativity, revolutionized the way we view space, time, and gravity. These theories were not just abstract concepts but were put to the test through experiments and observations. One of the first experiments that supported Einstein's theories was the observation of the bending of light around the sun during a solar eclipse. This phenomenon, predicted by Einstein's theory of general relativity, was confirmed by British astronomer Sir Arthur Eddington in 1919. The bending of light around massive objects like the sun provided concrete evidence of the curvature of space-time. Another key experiment that validated Einstein's theories was the measurement of the precession of Mercury's orbit. Scientists noticed that the orbit of Mercury did not match the predictions of Newtonian physics. However, when Einstein's theory of general relativity was applied to the calculations, the discrepancy was resolved. The slight shift in Mercury's orbit was a direct consequence of the curvature of space-time around the massive sun. Furthermore, the discovery of gravitational waves in 2015 provided further confirmation of Einstein's theories. Gravitational waves are ripples in space-time caused by the acceleration of massive objects. The detection of these waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) was a monumental achievement in the field of physics and a direct validation of Einstein's predictions from over a century ago.- Einstein's theories have not just remained theoretical concepts but have been put to the test through experimentation. The evidence gathered from these experiments has solidified the foundation of modern physics and cemented Einstein's legacy as one of the greatest scientific minds of all time.
