  Light indeed has no mass but it is still affected by black holes , this is simply because black holes can curve the space around them and light have to follow a path that is defined by the space (see: general relativity ) To put it more simply, it can be said that light has no mass but energy, so it will be affected by gravity, because gravity can also affect anything which has energy   Let’s try to understand this with the help of an example : ·         Consider a string with a bead on it ·         This bead can only slip along the string, In other words, the path of motion of the bead is guided by the string ·         If we keep the string straight the bead will also slide in along that straight path, and no other path Keeping this example in mind, now replace this string with space and bead with light Light will have to travel where there is space ...

  Black holes are one of the most interesting objects present in the universe Here is a complete guide to black holes, for you Summary  What are blackholes? It is a region in spacetime where the curvature of space tends to infinity Will a blackhole disappear? Yes a blackhole can disappear after sometime as it gets evaporated because of hawking radiation By which mechanism hawking radiation takes away the energy of a blackhole? Hawking radiation makes a blackhole loose energy because of combined effect of time dilation and fluctuations in quantum fields of space When a blackhole dies what happens to it? A blackhole ironically becomes brighter and brighter as it approaches it’s death, and ultimately dies in a burst of gamma rays The information paradox of blackhole and one of its potential solution It is unknown what happens to the information that goes inside a blackhole, a solution to this is that, information is present on the event horizon as a hologr...
