Black Holes

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
