3 Weird Facts About the Black Hole

What are Black Holes and how are they formed?

Black Holes are the most mysterious and weirdest objects in our universe. Black holes MAY be coined as Dead Stars. Stars are incredibly massive and are collections of mostly hydrogen atoms that collapse from enormous gas cloud under their own gravity. In it’s core, nuclear fusion crushes hydrogen atom to helium releasing tremendous amount of energy. This energy in the form of radiation , pushes against gravity maintaining a delicate balance between the two forces. (Radiation and Gravity). As long as stars undergo fusion, they are stable.

Some stars have way more mass than our Sun. These stars can fuse with heavier elements up to iron due to the heat and the pressure at the core. The fusion process that generates iron, does not creates any energy which breaks the balance between radiation and gravity. Hence the core collapses and within a fraction of a second the star implodes. This produces either a Neutron Star or a Black Hole.

Here are 3 Weird facts about Black Holes

1. Black Holes are INVISIBLE

Yes, Black holes are invisible and the only way to detect and study them is to observe the effect on nearby matter. This includes accretion disks. These disks are a disk of particles that form when gases and dust fall towards a black hole and quasars, jets of particles that blast out of super massive black holes.

2. Black Holes DISTORT Space and Time

A black hole is a region where a force of gravity is so strong that not even the fastest known entity in the universe “light” can escape it. When something crosses the event horizon ( the boundary of a black hole) it collapses into the black holes’ singularity which is an infinitely small and dense point. At the singularity, space, time and the laws of physics are not applicable.

3. There are multiple types of Black Holes

Scientists have theorized various different types of black holes. Stellar, Intermediate, Supermassive, and Miniature. Out of these the stellar and supermassive black holes are the most common.

Stellar black hole form when massive stars which are 3 to 10 times the mass of our Sun die and collapse. There could be millions of stellar black holes in our Milky Way.

Supermassive Black holes are gaints measuring million or even billions of times more massive than our Sun. Sagittarius A, the super massive black hole is at the center of our milky way which has a mass of roughly 4 million suns.

Black holes remained unknown till the 20th century. In 1916, using Einstein’s general theory of relativity, a German scientist named Karl Schwarzschild calculated that any mass can become a black hole if it were compressed tightly enough. But it was not until the theory became a reality. Astronomers studying the constellation Cygnus discovered the first black hole. Black holes are scattered throughout the universe wrapping space and time.
