Okay you said supermassive black holes could have formed from hundreds of smaller black holes merging together could you go into more detail about that? how close do the smaller black holes have to be one another?
Black holes can collide to create larger black holes. Once they are close enough their gravitation pulls the other and vise versa. There is no specific distance because it depends on the size of each black hole and their gravitational pull.
The matter that is absorbed by black holes is already accelerating/rotating very fast, however we are not able to exactly tell what the speed is once it enters the black hole. Black holes themselves are not accelerating.
Black holes are really hard to get a density. Basically, they are so dense that there is no known mechanism for providing sufficient outward force to counterbalance the inward pull of gravity, so they will collapse into an infinitesimally small size.
Though we cannot see black holes directly, they are so powerful that we can see their unmistakable, dramatic effects on the matter around them. There are three main lines of evidence astronomers look for, these include: A blaze of X-Rays, Super- powerful jets of matter, and Rapidly moving stars.
One of their basic properties is that they trap light. However, it is also true that nothing exceeds the speed of light. In fact, the theoretical prediction of black holes is due to the General Theory of Relativity, which is built on the principle that the speed of light in a vacuum is constant. The analogy of a cannonball falling back to Earth with the trapping of light in a black hole is only a crude and suggestive one that is not correct at a fundamental level (for one thing, the cannonball has mass, but light does not; it turns out that this difference is critical, because massless particles MUST travel at light velocity, but massive particles CANNOT travel at light velocity).

No. No one has ever seen anything enter a black hole because no one can see a black hole directly. Nothing can escape a black hole, not even light. When you look at a black hole you can see a glow coming from around it with a black center but you cannot see the inside and therefore, you can not see anything that would enter it.

ReplyDeleteBlack holes can collide to create larger black holes. Once they are close enough their gravitation pulls the other and vise versa. There is no specific distance because it depends on the size of each black hole and their gravitational pull.
Deletewhat is the closest black hole to our galaxy?
ReplyDeletethere is a supermassive black hole in the center of the milky way galaxy that is about 27,000 light years away
DeleteDo black holes accelerate or are they still?
ReplyDeleteThe matter that is absorbed by black holes is already accelerating/rotating very fast, however we are not able to exactly tell what the speed is once it enters the black hole. Black holes themselves are not accelerating.
DeleteWhat is the size range to classify a black hole as an intermediate black hole?
ReplyDeleteroughly 100 million to 1 million solar masses.
Deletedo you know the actual incredible density of a black hole?
ReplyDeleteBlack holes are really hard to get a density. Basically, they are so dense that there is no known mechanism for providing sufficient outward force to counterbalance the inward pull of gravity, so they will collapse into an infinitesimally small size.
DeleteIf we can not see a black hole, how do we know they exist?
ReplyDeleteThough we cannot see black holes directly, they are so powerful that we can see their unmistakable, dramatic effects on the matter around them.

Do you know how large the most massive black hole documented is?
ReplyDeletethe biggest black hole is located inside a galaxy named NGC 1277 and it is about the same mass as 17 billion suns.

DeleteDo you know the size of the smallest black hole ever formed?
ReplyDelete3.8 times the mass of the sun.
DeleteHave people ever observed something entering a black hole?
