What can we detect from matter that has crossed an event horizon?Group of answer choicesVisible light.Gamma bursts.Radio waves if the matter was traveling fast enough.X-rays if the matter was dense.Nothing.
Solution
Nothing. Once matter has crossed the event horizon of a black hole, it cannot be detected by any means. This is because the gravitational pull within the event horizon is so strong that nothing, not even light, can escape it. Therefore, we cannot detect visible light, gamma bursts, radio waves, or X-rays from matter that has crossed an event horizon.
