More About dark matter

Dark matter has been a mystery for a long time. Scientists found it by looking at how stars move. They saw stars moving in ways that did not make sense. So, they thought there must be more stuff we can't see.

Dark matter does not change our day. But it helps us know more about space. It shows us how stars and galaxies work together. This helps us learn about our own world.

In the future, we may find out more about dark matter. Scientists are using new tools to look for it. They hope to learn how it helps make the universe.
