Creation
Black Holes can be created by stars 100 times the density of our sun. These stars explode in Hypernova, leaving a black hole behind
- Fusion stops in a dying star, causing gravity to crush it's core to collapse
- A small black hole is formed, which begins to feed on the outer layers of the shell
- Within 1 second of forming, it expels more energy than our sun will produce in its lifetime, creating a Gamma-ray burst
Characteristics
- At the center of a black hole is a singularity, a point of infinite gravity
Gamma-ray bursts
- Caused by newly formed black hole consuming matter of the surrounding star
- Observable feature of a black hole, we see them everywhere
Super massive black holes
- One rumored to be at the center of our galaxy, 4 million times the density of our sun
- One in Andromeda is 140m * density our sun
- M87 = 20 billion density of our sun
- Quasars are explosions from SMBHs
