Vilasi G. Can gravity be repulsive? (abstract)
Speaker: Gaetano Vilasi
Title: Can gravity be repulsive?
Light carries energy and therefore is the source of a gravitational field. Geometric and quantum field theory an alysis suggest that, in special cases, gravity can be repulsive.
More precisely, it turns out that the Light is the source of non-linear gravitational waves corresponding, from a quantum point of view, to massless particles of spin -1.
These results give a possible solution to the old problem on the lack of gravitational attraction between two la ser beams moving parallel.
