7 Black Hole Science Facts, One of them is in Our Galaxy
Netgenz - Sains | A black hole is one of the objects in space that can attract light with the strongest gravitational force. Quoted from NASA, the gravity created by black holes is the result of dead stars. Here are seven unique pieces of evidence about black holes.
You can't watch black holes
The name black hole is given because of its color and character that attracts light. Because all light is absorbed by the black hole, we cannot see it. Some researchers can only notice by checking the temperature and radiation. In addition, it can be seen from the surrounding stars that are attracted to it.

You can't get out of a black hole
When you or an object gets into a black hole or black hole, there's no going back. Black holes have the strongest gravitational force and nothing around them can escape.
Anything near this hole will naturally be "spaghettified". This term was created to describe objects that will elongate and flatten like spaghetti before being drawn into it. Until now researchers do not know what can happen to some objects that enter the black hole.
Black holes suck nothing
This hole is often described as something that sucks all objects that fly near it. In fact, this is because the grab or gravity force is too great to look like a suction hole.
Black holes are the biggest source of energy
Black holes can produce more energy than the Sun. It is a result of the material orbiting around this hole. The material orbits at high speed due to the great gravitational force. Due to its extremely high speed, the material heats up to temperatures of over 500 million degrees Celsius. This event will create energy called blackbody radiation.
There is a supermassive black hole in the middle of our galaxy
Some experts believe that there are black holes in every galaxy. These holes are thought to serve as anchors for each galaxy.
The name of the black hole in the Milky Way Galaxy is Sagittarius A, which has 4x the energy of the Sun. However, the location is so far away that it doesn't attract the Earth or the Sun. It is estimated that the distance is 30,000 light-years from Earth.
Time in the black hole is slower
It is related to Einstein's theory of relativity. The faster we move, the slower time will pass us.
Evaporating black hole
This theory was put forward by Stephen Hawking in 1974. Hawking said if a black hole evaporates its own mass into space. This will continue to happen until the power source runs out. This event is called Hawking radiation.
