Dark Matter Facts

•Only 20% of all known matter is the matter we can see, or “normal matter.”

•The other 80% is Dark Matter, which is also around us just as much as normal matter is.

•Dark Matter doesn’t interact with light or ordinary matter very frequently.

•Dark Matter is a “Perfect Fluid,” meaning its molecules do not transfer heat, and they move around without touching one another.

•We have been looking for it since 1933.

How Do We Know Dark Matter Exists?

Galaxy Rotation CurvesWithout Dark Matter, stars and planets in our galaxy would fly off

into space.
