평면파 형태의 중력 충격파는 점 전하나 점 질량과 같은 점 소스의 고전적 장에 섭동을 일으키며, 이 섭동은 구면파 형태로 외부로 방출되는 것처럼 보인다.
Plane-fronted gravitational shockwaves create perturbations in scalar fields, leading to outgoing spherical shockwaves and a plane scalar shockwave accompanying the initial gravitational wave.
This research paper establishes a theoretical connection between the gravitational effects of a continuous photon gas and a collection of discrete gravitational shockwaves produced by null point particles, providing insights into the nature of gravitational fluctuations.
