On a final note, we can work out the area where even light cannot escape by using the Schwarzschild radius. This diagram can show us many things, for example, how black holes don't have a gravitational pull which goes across the whole universe. Supermassive black holes (often found at the centre of galaxies)įinally, there are 3 main areas inside a black hole. There are multiple types of black holes including: Black holes can also eventually dissipate, due to a mechanism called Hawking Radiation Black holes don't have the colour black, they don't have a colour because we can't see any light coming back from them. Small stars that explode in a supernova create something called neutron stars.Ī black hole is a area in space with a gravitational field so strong not even light can escape. The second way a supernova can happen is in a binary star system - where if there is a white dwarf, it steals matter from the other star and eventually it accumulates so much matter that it explodes.Ī singularity is caused by the big stars, not small ones. A supernova is where a star is caused when there is so much matter in the centre of a star (at the end of its life) that the star cannot support its own gravitational force, and it collapses in on itself and explodes. Density and matter are different things.Ī singularity is often created in a supernova explosion. When you have a singularity matter does not go to infinity. So basically, a singularity is a point in space where a lot of matter is squeezed together in a very small space. The singularity is at the centre of the black hole, and is often hiding behind an event horizon. A singularity is a point in the universe where matter is infinitely dense.

The singularity is nigh
