Without science, we wouldn't be able to uncover all the mysteries of the universe. Here are some examples of different terms relating to the science of space.
gravity
The force of an object that pulls other things towards it. All things have gravity, but the biggest things have the most noticeable gravity. Planets and suns for example, have massive gravities that we can observe. A person falling is pulled to the earth's gravity.
air

atmosphere

pressure
