The laws of physics control every object in space. People whose work is to study space are known as astrophysicists due to how connected this branch of science is with looking up. Physics is the study of how matter and energy behave. It looks at how objects interact, the forces that control them, and the underlying laws describing how the physical world works. Physics covers a wide range of scales, from the smallest particles to the vast structures of the Universe.
