Black holes are really fascinating things. Thanks to Stephen Hawking, George Ellis and Roger Penrose, they went from being a real mystery to something we think we know pretty well today. This is not to say that we have discovered all its secrets, but it is true that at least We have a pretty good idea of ​​what they are. and how they behave.

In general, the most widespread and accepted definition says that black holes are finite regions of space that have such a huge concentration of matter in them which generate massive gravitational fields to such an extent that they create an attractive effect so intense that not even light can escape from it.

According to Stephen Hawking these emit a certain type of radiationalthough in some cases the radiation appears not to come from the black hole itself, but from its accretion diska disk-like structure that normally consists of gas and dust that orbits a black hole.

The enormous gravity that a black hole has causes the singularity to be surrounded by a closed surface known as event horizon, it separates the black hole region from the rest of the universe and causes space-time to curve. As we said, once something enters this event horizon, it cannot escape.

We also know that there are different types of black holes today that are classified based on their mass as well as other aspects such as their charge and angular momentum. If we talk about the size, the differences between these types of black holes they are also hugeAnd to demonstrate this, NASA shared a very interesting video where they show us the size of the smallest and largest black hole that we know of in a comparative way.

We start with our Sun as a reference point and from there the video changes based on the size of each of these black holes. How can you, the latter are so huge that I think the super massive concept is too small for them, because TON 618 has a mass equivalent 66,000 million soles.
