What is Stephen Hawking's profession?

Stephen Hawking's profession was theoretical physicist. His research used mathematical models and physical theory to investigate gravity, black holes, cosmology, and the structure of the universe.

Hawking was also accurately described as a cosmologist and theoretical astrophysicist, but “theoretical physicist” is the broad professional label that best fits the quiz question. Unlike an experimental physicist, he primarily developed ideas and calculations rather than conducting laboratory experiments. His work often explored situations that cannot be recreated on Earth, such as the behavior of spacetime near a black-hole horizon or the earliest moments of the universe.

He studied physics at the University of Oxford and completed a PhD in applied mathematics and theoretical physics at the University of Cambridge. At Cambridge, he became Lucasian Professor of Mathematics, a position associated with major advances in mathematical physics.

A common misunderstanding is to label Hawking simply an astronomer because he studied stars and black holes. Astronomy generally emphasizes observing objects in space, while Hawking's specialty was using theoretical physics and mathematics to explain the underlying laws governing the cosmos.
