the purpose of black hole is still a mystery but one thing for sure is that they have a very strong gravity in the middle of the black hole. some says these gravity is what holding galaxy together and that the centre of the galaxy including the Milky Way is a black hole. This could means that Earth itself could be circling around a black hole for all we know it. Without it, our galaxy would fall and split apart and the Milky Way will not exist.
What else can I help you with?
How many black holes have people discovered?
If you know,there lies a black hole at the center of every galaxy,so the number of galaxies in the universe,same number of black holes.But there could be trillions of galaxies,witch also means trillions of black holes. There maybe a black hole in the center of every galaxy but there are also called stellar black holes. Stellar black holes can be find ANYWHERE in space.So it is not only the ammount of galaxies. There is a unknown answer to this question.There might be billions of black holes. Scientists do not know yet. Since we can only see about 13 billion lightyearsof the Universe from this position, its impossible to know even an estimated number of anything in the universe. That's including black holes.
What do black holes orbit?
No. There are no black holes in our solar system. Based on current models, the smallest stellar mass black holes are at the very least about 3 times the mass of the sun. Therefore, if there were a black hole in our solar system the sun would either orbit it or the two would orbit about a common center of mass.
Is this universe the product of a black hole from another verse?
There have indeed been some speculations that this may be the case. However, for now it is impossible to verify this. =========================== According to hyper sphere theory it suggest so i.e. the universe is like the event horizon of another universe from a 4 D universe's black hole. This model of the universe helps answers why the temperature of the entire universe is not uniform. According to Big Bang theory the temperature of the universe should have had been evenly distributed by now but this is not the case. A Canadian team of scientists proposed this theory that our universe might in fact be a the membrane of black hole in a 4th dimensional universe. Computer models show that the the 3 D membrane(our universe) surrounding the black hole is expanding. Like there are 2 D event horizons along the 3 D black holes we are the 3 D event horizon around a 4 D black hole called a hyper sphere.
How long do black holes last?
Black holes are expected to last for an extremely long time, potentially billions to trillions of years. They slowly lose mass due to a process called Hawking radiation, but the rate of this loss is very slow for most black holes, making their lifespan incredibly long.
Resolution of a corner of the universe?
At the corner of the universe, physical laws as we know them might break down or behave oddly due to extreme conditions or unknown phenomena. Our current knowledge of physics may not provide a complete understanding of what occurs in such extreme regions, such as near black holes or at the edge of the observable universe. Further exploration and advancements in theoretical physics are needed to unravel mysteries in these corners of the universe.
If scientists cannot see black holes and do not know for certain that they exist why might studying them be important?
The assumptions are not quite correct.Scientists CAN see black holes. In fact, black holes are among the brightest objects in the Universe. Of course, light can't escape from WITHIN the black hole; rather, what we see is the accretion disk. Also, scientists are PRETTY SURE that black holes are real. As to why it is important: Black holes are fascinating objects by themselves. They also seem to play an important role in galaxy formation.

Why were black holes named that?
The idea is that nothing can escape the black hole, not even light - so they might be quite dark. However, if matter falls into the black hole, it gets accelerated so much, before reaching the event horizon, that it emits a lot of radiation - as a result, some "black holes" are among the brightest objects in the Universe! For more information, read the Wikipedia article - or some other sources - about quasars.
Is there such thing as big black holes?
While scientists have never actually SEEN a black hole (they are called "black holes" because their gravity is so great that not even light can escape!) we believe that super-massive black holes are at the hearts of most galaxies. These super-massive black holes might be the mass of a million stars the size of the Sun, or larger.

How long will the black holes be around?
Very, very long. A black hole will gradually evaporate, but this takes much longer than the current size of the Universe. A black hole of the mass of our Sun would take about 1067 years to evaporate, while a supermassive black hole might take 10100 years or more to evaporate (depending on its mass) - and this assumes it doesn't continue gobbling up matter in the meantime. Currently, a stellar black hole (as well as larger black holes) will absorb background radiation at a faster rate than they evaporate. For comparison, the current age of the Universe is only about 1.4 x 1010 years.

Do black holes suck us back in time?
There is a theory that it might, but nobody really knows.
What did Stephen Hawking invented?
UK physicist and cosmologist Dr. Stephen Hawking is not known to have invented anything. He is a physicist at the Centre for Theoretical Cosmology in Cambridge, England. However, he and physicist Roger Penrose provided much of the mathematical support for the existence of black holes, and the means by which they might form and dissipate. The theoretical loss of mass by a black hole is referred to as Hawking radiation.
When a blackhole meets another black hole what happens?
When two black holes get close enough together, they might merge, to form a larger black hole.
