Theoretical physics

Theoretical physics is a branch of physics that uses mathematical models and abstractions of physical objects and systems to explain and predict natural phenomena. It is, in the broadest sense, the at
Visual representation of a Schwarzschild wormhole. Wormholes have never been observed, but they are predicted by mathematical models in general relativity.

Albert Einstein was a German-born theoretical physicist best known for developing the theory of relativity. Einstein also made important contributions to quantum theory. His mass–energy equivalence fo

…and it is perhaps fair to say that neither has been fully absorbed even now, a hundred years later. The special theory of relativity, published by Albert Einstein in 1905, resolved the conflict between Newtonian mechanics and electromagnetism by rethinking the concepts of space and time from scratch. The general…
