The
Equivalence Principle, or the Universality of Free Fall, is the
cornerstone of General Relativity and, thus, of modern physics. It has
been tested and confirmed with very high precision. Recently quantum
gravity and unifying theories predict tiny deviations from the Equivalence
Principle. This gives additional motivation for improving the experimental
efforts. This conference is dedicated to the meaning of the Equivalence
Principle, to approaches leading to violations of the Equivalence
Principle, and to the past, present, and future tests. |
