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.

into space.
