Question
Because of stellar nucleosynthesis, the spectra of old stars show more heavy element than those of young stars. In a neutron star, the protons and electrons are fused together, leaving only neutrons with no charges or repulsions. A massive star will fuse heavy elements only up to silicon before collapsing. Nothing can travel faster than the speed of light. According to general relativity, space is warped, or curved, by matter. Although visible light cannot escape from a black hole, high-energy radiation, like gamma rays, can escape. The present laws of physics break down near the center of a black hole. Because of their immense size, black holes moving through space consume huge quantities of interstellar matter along their paths. Both space and time are warped near the strong gravitational fields of neutron stars and black holes. The closer the observer comes to the event horizon, the faster his watch runs.Explanation / Answer
