The laws of physics shape everything we see in space. Scientists who study space using physics are called astrophysicists.
Physics explores how matter and energy behave. It looks at how objects move, how forces act on them, and the rules that describe how the physical world works.
These ideas apply across an enormous range of sizes. Physics helps us understand the smallest particles as well as the largest structures in the Universe.
- How do we measure things in space?
- How do objects move?
- Where does energy come from?
In this section, you can explore key ideas such as gravity, light, matter, and many other topics that help explain how the Universe works.
