The Big Bang theory says our universe was created when a tiny (billions X smaller than a proton), super-dense, super-hot mass exploded and began expanding very rapidly, eventually cooling into the stars and galaxies of today.

Historians once debated the relative importance of the "great man" theory of events compared to the "inevitable forces" or trends as the shapers of history.
Einstein's greatest contributions to physics were his synthesis of mechanics and electrodynamics through his relativity theory, and his challenge to Newtonian physics through his quantum theory.

Isaac Newton said he was inspired to formulate his theory of gravitation when he witnessed an apple falling from a tree. Cartoonists have since embellished the story, suggesting the apple fell directly on Newton’s head.
