how is a blackhole formed?

A black hole is formed when a super massive star reaches iron in nuclear fusion the stars core is not hot enough to fuse iron so the star is not producing the radiation to fight against the gravity of the massive star then it collapses it is so dense that it shrinks to a huge a mount of mass over very little matter ,like less then an atom. Then it becomes so dense that at a certain point(horizon point, The Black stuff) Light can't even come back because there is so much gravity.

Interstellar and Hawking radiation

Many of the more obscure physics concepts are incredibly interesting, but often take a technical mind and a lot of background to really wrap your head around. I chose Hawking Radiation in particular because it does not contain a lot of jargon or technical terms, but is still conceptually difficult.

  All particles, objects, matter, and even light will appear to freeze directly at the event horizon. It will slowly redshift as the wavelengths of light from it that are returning to the observer get stretched, until it completely vanishes. Directly on and past the event horizon is when the effect of gravity is impossible to overcome.
