He Proposed The Special Theory of Relativity

Special relativity - one of the major accomplishments of Albert Einstein, is a theory that deals with "exceptional" situations, such as massive energies, ultra-high speeds, and galactic distances, all without the difficulties of gravity.

Because of the contradictions between Newtonian mechanics and Maxwell's electromagnetism equations, Einstein wrote his famous article 'On the Electrodynamics of Moving Bodies' on September 26, 1905. While dealing with circumstances near the speed of light, Einstein advocated major alterations to mechanics. Einstein's special theory of relativity was later named after him. It was backed up by experimental proof and quickly gained general acceptance. Special relativity is still the most accurate model of motion at any speed today.

According to Wired, Albert Einstein established that the laws of physics are the same for all non-accelerating observers in his theory of special relativity, and he demonstrated that the speed of light within a vacuum is the same regardless of the speed at which an observer moves. As a result, Einstein discovered that space and time were intertwined to form the space-time continuum. Moreover, events that happen at the same time for one observer may happen at different times for another.
