What is the difference between Dark Matter and Anti-Matter?

Dark Matter is kind of like ghost matter. It can't be seen, it can't be touched, it can't be felt. So how do we know it even exists? Because it gives off gravity that affects other planets.

Now, anti matter is a very rare form of matter (mostly found in the core of stars) that has the opposite charges of regular matter. In anti matter, protons are negative, and electrons are positive. However, anti matter doesn't normally last long? Why, because the moment it touches any form of normal matter, it explodes.

Haha thanks Mr, its seems you are not only well versed in comic books!
