Beyond the myths about black holes, there are facts that support interest in these cosmic objects.
National Aeronautics and Space Administration (PotIts abbreviation in English) explains Black holes Astronomical objects with a Gravitational force Nothing, not even light, is too strong to escape them.
Regardless of a definition, there are some facts that help better understanding The size and influence of these objects in the universe. Much has been said and speculated about them, no less: what is known has generated many questions and conjectures around the subject.
To broaden the understanding of black holes, the following are listed Five Basic Truths About their nature Mysterious objects of the universe.
5 facts to understand the nature of black holes and what they are
What is the origin of black holes?
As stated therein PotMost of them Black holes formed from the remnants of a massive star that dies in a Supernova explosion. This occurs with “shining giants” that are three times the size of the Sun, and on the other hand, Star collisions Even bigger holes appear.
Parts of a black hole
published University of ChicagoSlabBlack holes They have two parts. The first corresponds Event does not spread. It can be thought of as the surface of matter, although it is actually the point where gravity is so strong that nothing can escape. Most of what is known about these cosmic objects lies there.

The rest of the holes are in the center. gets the name Singularity And that, according to University Quoted, “A point infinitely small and infinitely dense.” Astronomers still don’t know what it actually looks like. of this section.
Types of black holes
The Black holes Get their classification Size. In this sense, the following categories are identified:
- Star
- intermediates
- Colossal
is between the first three and 100 solar masses; 100 to 10 thousand seconds; and the third are all above the last figure.
What do black holes eat?
Contrary to popular belief Another fact is that black holes eat/absorb stuff. The University of Chicago Indicates that an object must properly land in the “gate”, or Event does not spread, to be trapped by the loophole. Stars and other celestial bodies can orbit these planets without swallowing them, as long as their motion is not disturbed.

For example, we have Sagittarius A*A supermassive black hole at the center of a galaxy milky way. It was observed, above all, to feed on interstellar gas and dust.
How were black holes discovered?
Thanks to the general theory of relativity, Albert Einstein 1916 predicted the existence of these objects. It was discovered many years later Cygnus X-1The first hole scientists saw.
The story of discovery began in 1964, when a group of astronomers saw the first signs. Cygnus X-1 By pinpointing celestial sources of X-rays using a sounding rocket. Later, in 1971, it was determined that the emissions came from A Bright blue star A strange dark object orbiting was later identified New Cosmic Corporation.
