Why can't light escape a Black Hole? Why does light bend around a black hole? Why can't light which has not mass escapes a Black Hole? Join Physicist Brian Cox as he answers one of the most interesting astrophysics questions asked to him. The interviewer asks: "Since gravity pulls things into a Black Hole, why can't light being mass less particles escape a Black Hole?" In response to the question, Brian Cox starts by explaining the theory of Gravity proposed by Isaac Newton and Einstein. He adds how Newton's theory of Gravity suggests that Gravity pulls objects inward, whereas Einstein's theory of Gravity, which is a more refined version suggests that if you imagine a universe, you can imagine space and time often called as the "fabric of the universe". Professor Brian Cox then gives an example of how you can place a cannonball on the fabric of the universe, and it curves the surrounding area. At the end of this #shorts he talks about how things that go inside a Black Hole will curve in space and time rather than simply going inside it. So, that's what happens with particles of light or photons when they get curved around a Black Hole. #blackhole #hawkingradiation #briancox #singularity #science #podcast #cosmology
