An object whose gravity is so powerful that not even light can escape it. Event Horizon Black Hole Can be made by some massive stars if enough mass falls onto the core. The spherical surface of a black hole. Schwarzschild Radius Event Horizon The radius at which escape velocity equals the speed of light. The radius of the event horizon. Black Holes Mass Singularity Gravity crushes all the matter of a neutron star into a single point, or ____. Strongly warps space and time in the vicinity of the event horizon. Gravitational Redshift Light waves take extra time to climb out of a deep hole in spacetime, leading to a ____....
