The document discusses how black holes form from large stars collapsing under their own gravity. It defines a black hole as a massive object formed by gravitational collapse that has such intense gravity that no light can escape. It describes the three main layers that make up a black hole - the outer event horizon, inner event horizon, and the strongest central singularity.

2. How Black Holes
Form..
When a large star runs out of fuel it
cannot hold its weight. The pressure
from the stars layers of hydrogen
press down forcing the stars to get
smaller and smaller. Eventually the
star will get smaller than an atom.

3. Definition Of A Black
Hole
A theoretical massive object, formed
at the beginning of the universe or by
the gravitational collapse of a star
exploding as a supernova, whose
gravitational field is so intense that
no electromagnetic radiation can
escape

4. Description Of Black
Holes
Black holes are made up of three main parts.
The very outer layer is called the Outer Event
Horizon. The middle layer is called the Inner
Event Horizon. The center layer is called the
Singularity. The Singularity layer of the hole is
the strongest.

5. Interesting Facts :) !
There are currently 14 known black holes.
The known closest black hole to Earth is Cygnus X-1,
located about 8000 light years away.
As black holes age, they gain more mass as they suck in
matter.
Although black holes have a VERY strong suction force,
they do not have the strength to swallow the whole
universe.
Black holes can suck up other black holes and usually the
bigger one swallows the smaller one.
