Albert Einstein
Albert Einstein was a German physicist who revolutionized our understanding of gravity with his theory of relativity. He proposed a type of 'bridge' that connects two points of space-time, paving the way for future wormhole theory. In 1905, he wrote a paper on Brownian motion and another on using 'photons' to describe the photoelectric effect. Einstein's theory predicts time dilation and length contraction at extremely large speeds and describes the curvature of spacetime.
