The Possibility of a "Theory of Everything"

From Democritus believing that everything was made of basic building blocks (which he called Atoms" to Pythagoras beliving that the world was made of waves, the field of physics has long been researched and comptemplated. . Each physicist has contributed towards shaping and reshaping physics. However, the revolution of physics was achieved by unification. First unification was achieved after Newton's work leading to unifying gravity and astronomy. Second by unifying electricity, magnestism and light. Third might revolve around unifying particle phsyics and Einstein's theories of gravity.
