Black holes are a very strange thing in our
universe. No one knows what exactly its made out of and how it
looks like. The reason why we know there’s a black hole is
because of the surrounding objects such as stars and radiation.
Black holes are basically a collapsed inner core of a star that have
mass. Stars have two stages to grow into a black hole. They
first grow into a giant star and it turns into a supernova. The
inner layer of the stars core turns into black hole. Gravity is
trying to crush the star's core, but because of fusion in the star, it
continues to grow until it can no longer fight against gravity.
Basically when a star has a large mass, they have a short life, but
when they have little mass, they live longer. Stars have
to have a large mass in order to turn into a blackhole. Black
holes gravitational pull is so strong that once light
is inside what is called the event horizon, it can’t escape.
Anything near the event horizon will be sucked in, even stars.
When material is sucked into the black hole, it becomes bigger.
The material being sucked into the black hole will be accelerated and
heated to very high temperatures. In result, there is an emission
of X-ray light. More X-ray light is generated when some of the
material swirling into the black hole, but instead of falling into the
black hole, it spits it back out at fast speeds. Some material
wont reach the event horizon, but instead will be caught in a magnetic
field that exists around the black hole. There are super massive
blackholes called stellar. The middle of our galaxy has a
stellar. Black holes are the
strangest things that exist in the universe.
