Black holes are formed after a large star loses its thermonuclear fuel in its core and collapses on itself. The star is blasted into pieces, which is a phenomenon called a supernova and forms a black hole.
Many people believe that black holes are “wormholes” leading to alternate dimensions and realities. If you enter a black hole, it is hypothesized that you will get transported to another point in time and space. This, however, is not true because once a particle passes through the singularity, it ceases to exist.
A black hole has three parts: the outer and inner event horizon and the singularity. The event horizons are boundaries in the black hole that do not let anything escape, even light! The particles are compressed into the singularity, a single point where the mass is condensed. In the singularity, the laws of physics stop working and the particles are crushed into infinity.
There are three types of black holes: stellar, supermassive, and intermediate. Stellar black holes are small and compact and are formed by a small star collapsing. Supermassive black holes are exceptionally large and are at the center of every universe. They are formed by multiple black holes merging or multiple stars collapsing together. Intermediate black holes are medium sized and are formed by star clusters colliding together in a chain reaction.
Binary black holes have recently been discovered; they are two black holes spinning around each other. There are two theories of how they formed: two stars died at the same time having the same spin rotation, or black holes in a stellar cluster sunk into the center and paired up.
There are so many things we still do not know about black holes! They are one of the most intriguing phenomena in the universe! As technology and research advances, we will discover more interesting things about these dark voids and explore the unknown mysteries of black holes!
