In Einstein's general theory of relativity, both matter and energy can create a gravitational field. This means that the energy of a light beam can produce a gravitational field. My current research considers both the weak and strong gravitational fields produced by a single continuously circulating unidirectional beam of light. In the weak gravitational field of a unidirectional ring laser, it is predicted that a spinning neutral particle, when placed in the ring, is dragged around by the resulting gravitational field. [R. L. Mallett, "Weak gravitational field of the electromagnetic radiation in a ring laser"

The problem is how is he going to put the concept in practic
