A black hole in space.

Bobo.id – friends must have heard of black hole or black holes in outer space.
This black hole is often adapted in various films as something dangerous.
On many films a black hole will appear to attract a lot of objects around it.
So what exactly is a black hole? And where do black holes come from?
Origin of Black Hole
Black holes were first thought to exist by Albert Einstein in 1916 through a general theory of relativity.
But the name black hole or black hole just emerged from an astronomer from America, namely John Wheeler in 1967.
For several years black holes were only referred to as theoretical objects in the form of physical black holes that were first discovered in 1971.
After many observations, it is known that black holes have such a strong attraction that even light cannot escape.

Even the gravity of a black hole is said to be able to pull space material into a small space.
Black holes are still being observed, until researchers begin to know their origin and approximate size.
Black Hole Size
Researchers call black holes large or small.
The smallest black holes are thought to be as small as an atom.
Despite having a very small size, black holes can have a large mountain mass.
Mass in question is the amount of matter or ‘stuff’ in an object.
In addition, there are also black holes called ‘stars’ and have a mass that reaches 20 times more than the mass of the Sun.
Huge black holes called by researchers with the name ‘supermassive’ which has a mass of more than one million Suns.

In the Milky Way galaxy where Earth is located, there is a supermassive black hole called Sagittarius A.
Formation of a Black Hole
The formation of black holes is still in an estimate by scientists.
Small black holes are said to have formed when the universe began to form.
The creation of black holes is also said to originate from the center of a large collapsing star.
Scientists also call the largest black holes appear together with galaxies where the black hole is located.
Could Earth Enter a Black Hole?
In the Milky Way galaxy there is a very large black hole.
However, the black hole does not revolve in the space of stars, moons, and planets.

So there is no possibility of Earth falling into the black hole closest to the solar system.
Even if the black hole had the same mass as the sun and replaced it, the Earth would still not be attracted to it.
Earth will instead orbit the black hole as it orbits the sun as it is now.
Those were various explanations about black holes which are considered dangerous because they can attract many things into them.
