Black Holes
Black Hole Unit Notes
A black hole forms when a star reaches a certain critical density, and its gravity causes it to collapse to an almost infinitely small pinpoint. Black holes form from the death (implosion) of neutron stars.
Objects too heavy to be neutron stars collapse to black holes.
As mass increases, the gravitational pull increases .
If the gravitational pull is such that light cannot escape, then a black hole forms.
There are Three classifications of black holes.
1. Stellar-mass: 3 to 20 times the mass of our sun
2. Supermassive: millions to billions of times the mass of our sun
3. Mid-mass-between stellar-mass and supermassive
•The black hole is surrounded by an event horizon which is the sphere from which light cannot escape
•The center of the black hole is a point of infinite density and zero volume, called a singularity
Cygnus X-1 binary system was the first black hole discovered.
