Theoretical astronomy

Theoretical astronomy is like playing a game of make-believe with the stars and planets. We use this game to try and understand how things work in space. We use a lot of math and imagination to figure out things like how stars were born, what happens when they die, and how planets move around them.

It's kind of like playing with blocks. You have all of these different shapes that you can put together in different ways to make something cool. In theoretical astronomy, we have all of these different ideas and concepts that we piece together to create a picture of how the universe works.

Sometimes we come up with new ideas and we test them out to see if they work. It's like trying to build a tower with blocks, and you keep adding new blocks to see how tall you can make it before it falls over. In the same way, we keep adding new ideas to our understanding of the universe to see if it matches up with what we observe.

Theoretical astronomy is a fun game, but it's also very serious work. By understanding the secrets of space, we can learn more about our own planet and our place in the universe.
