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)
“It takes twenty or so years before a mother can know with any certainty how effective her theories have been—and even then there are surprises. The daily newspapers raise the most frightening questions of all for a mother of sons: Could my once sweet babes ever become violent men? Are my sons really who I think they are?”
—Mary Kay Blakely (20th century)
