Black Holes

Black holes are mysterious objects formed from collapsed stars. They have extremely strong gravity that does not allow anything, including light, to escape once it passes the event horizon. Black holes are made up of an event horizon and an accretion disk, where gases are pulled in at high speeds. While black holes obey physics, the laws of gravity break down at the event horizon. They can be detected through their gravitational effects on nearby stars and radiation given off by the accretion disk. Black holes come in different sizes and masses, with some being supermassive in the centers of galaxies.

Black holes

Dalton Smith

What are black holes? What are they made of?


What creates them? Black holes are one of the
biggest mysteries of space. There are many
theories of black holes. Some theories are they
slow down time, they are wormholes, and that they
are an infinite void.
Black holes have 2 main parts. The event
horizon and the acceleration disk. The event
horizon is the outer layer of the black hole. The
acceleration disk is the gases going into the black
hole to create a speeding disk it also gives off xrays. A black hole is a collapsed star that keeps its
mass in a more compact form that why nothing can
leave a black hole not even light. Black holes obey
all laws of physics except for in the event horizon
which is the outer layer of the black hole that if you
go past that the law of gravity breaks. Black holes
form from dying stars. There are millions of billions
of black holes but none are close enough to harm
earth. Black holes distort what you see when you
are going into one. They are stars that fell from
their own gravity and kept there mass. Black holes
have an electric force. When a black holes collide
they make bigger black holes. The nearest black
hole is about 1,600 light years away.
There are different kinds of black holes. A black
hole could kill you in many ways. Some examples
are, ripped apart, crushed, and stretched. Black

holes might create elements for life like oxygen,


carbon, iron, and hydrogen. Black holes are
spheres that spin. Black holes infinitely grow the
black hole in the middle of the Andromeda galaxy
is a supermassive black hole and its thirty million
times heavier than our sun. Black holes make
noises but you would have to special instruments
to hear it. Any matter can become a black hole but
most matter does not have enough gravity and
mass to become a black hole. You cannot see a
black hole because the event horizon is pure black
you can only see stars orbiting a black hole and the
acceleration disk. Black holes leak radiation and
thats how most astronomers find black holes is
their radioactive activity and x-rays of the
acceleration disk.
In conclusion, black holes are amazing
mysteries. Scientist are still trying to find more
information about black holes and other mysteries
in space.
