Apple and gravity. Conceptual image of an apple falling under gravity, represented by a spacetime grid. It is said that Isaac Newton's formulation of his theory of gravity was prompted in the 1660s by seeing an apple fall from a tree. Spacetime arose from the theories of relativity, including the work of Albert Einstein in the early 20th century. | |
