is important to understand the notion of partial theories. For example, Newton’s Law of Gravitation is very accurate only when gravity is weak – and must be replaced by Einstein’s general relativity in strong gravitational fields. Similarly, relativity must be replaced by quantum mechanics when examining interactions on a microscopic scale, such as the big bang singularity, or at the edge and centre of a black hole.

gravitation might be due to certain properties of the medium it’s falling in, that is, space itself.

Cosmology is the study of the whole Universe and much of the subject is based on wide-sweeping hypotheses. Gravitation determines the large-scale structure of the Universe or, more simply, keeps the planets star and galaxies together. It is the most important concept for work in this field.

Berlin, November 1915. Albert Einstein (1879-1955) had just completed his theory of general relativity, a mathematical structure in which curved space and warped time are used to describe gravitation

Stephen Hawking is called a relativistic cosmologist. This means he studies the Universe as a whole (cosmologist) and uses mainly the theory of relativity (relativistic).
