ABSTRACT: The
gravitational signature of antimatter has received growing interest during the
past few decades. Much of the theoretical work in ordinary tensor gravity rules
out any difference in the gravitational interaction of matter and antimatter.
Fundamental principles and theoretical models describing the nature of matter
and antimatter are reviewed. The implication of a probable repulsive field
between matter and antimatter and its far reaching consequences on certain
cosmic issues, such as the early phase of the Big Bang, the Hawking radiation,
virtual particle production and annihilations, are discussed. Experiments
designed to probe the gravitational signature of antimatter are reviewed, and a
new space-borne experiment to probe the nature of matter-antimatter
interactions is proposed.
