Three Theories
The CPT theorem asserts that antimatter should attract antimatter in the same way that matter attracts matter. However, there are several theories about how antimatter gravitationally interacts with normal matter:
- Normal gravity: Standard theory asserts that antimatter should fall in exactly the same manner as normal matter.
- Antigravity: The theoretical analysis also focused on whether antimatter might instead repel with the same magnitude. This should not be confused with the many other speculative phenomena which may also be called 'anti-gravity'.
- Gravivector & Graviscalar: Later difficulties in creating quantum gravity theories have led to the idea that antimatter may react with a slightly different magnitude.

Famous quotes containing the word theories:
“We do not talk—we bludgeon one another with facts and theories gleaned from cursory readings of newspapers, magazines and digests.”
—Henry Miller (1891–1980)
“The real trouble about women is that they must always go on trying to adapt themselves to men’s theories of women, as they always have done. When a woman is thoroughly herself, she is being what her type of man wants her to be. When a woman is hysterical it’s because she doesn’t quite know what to be, which pattern to follow, which man’s picture of woman to live up to.”
—D.H. (David Herbert)
