Is there any way to determine how big a black hole is? I googled the question but I didn't find any answer.
jnorman said:yes, but it should be noted that the EH is an effect caused by the BH. the actual BH itself has no size, ie, the singularity proper has zero volume.
A black hole is a region in space where the gravitational pull is so strong that not even light can escape from it. It is formed when a massive star dies and collapses under its own gravity.
The size of a black hole is determined by its mass. As more matter is pulled into the black hole, its size and gravitational pull increases. Some black holes can be as small as a single atom, while others can be millions or even billions of times the size of our sun.
The largest known black hole is known as TON 618 and is estimated to have a mass of 66 billion times that of our sun. It is located in a distant galaxy and is about 10.4 billion light years away from Earth.
Yes, black holes can merge together in a process known as a "black hole merger". This occurs when two black holes orbit each other and eventually merge into one larger black hole. This phenomenon has been observed by scientists through the detection of gravitational waves.
Once an object crosses the event horizon (the point of no return) of a black hole, it will be pulled towards the center of the black hole. As it gets closer, it will experience extreme tidal forces and will eventually be torn apart and added to the mass of the black hole.
