Question:
If Matter and Anti- matter are oppsite, then would dense anti-matter create anti-gravity,and would superdense anti-matter create the oppsite of a black hole?

Replies:
Matter and anti-matter are made of opposite particles, but these opposite particles do not have negative masses. An electron and a positron (an anti-electron) have opposite charge, but they have the same mass. As a result, gravity is the same for both particles and for antiparticles.
