WebOct 15, 1990 · Abstract. We study the gravitational back reaction of local cosmic-string loops as they shrink due to gravitational radiation. We chart the evolution of the shape and radiation rate of the loops. Cusps survive gravitational back reaction, but are weakened. Asymmetric string trajectories radiate momentum and hence undergo a rocket effect, but ... WebThe behavior of a quantum test particle satisfying the Klein-Gordon equation in a certain class of 4 dimensional stationary space-times is examined. In a space-time of a spinning cosmic string, the wave function of a particle in a box is shown to acquire a geometric phase when the box is transported around a closed path surrounding the string.

WebJun 28, 2024 · A cosmic string is a kind of structure that has been discussed in theoretical physics for quite a while. I think most attempts to think about quantum gravity allow such things, so I don't think a cosmic string would necessarily distinguish among quantum gravity theories. In that sense it would not necessarily support string theory over other ...
