An astrophysicist explains one way the universe might work at the fundamental level ABC Science / By Geraint Lewis Posted Thu 29 Aug 2024 at 12:24am String theorists say the universe is built of infinitesimal vibrating strings — but how do you prove that? (Getty Images: Paper Boat Creative) In general relativity, a black hole is defined as a region of spacetime in which the gravitational field is so strong that no particle or radiation can escape. In the currently accepted models of stellar evolution, black holes are thought to arise when massive stars undergo gravitational collapse, and many galaxies are thought to contain supermassive black holes at their centers. Black holes are also important for theoretical reasons, as they present profound challenges for theorists attempt…
