NO, to see something you have to be able to intercept light reflected from that thing's surface. Black holes have an escape velocity greater than the sped of light so there is no reflected light and they cannot be seen. If they cannot be seen they cannot be pretty ... or ugly.
Black holes are a bit hard to detect, so I am pretty sure that not all black holes in this galaxy are known - and I suspect there is not even a decent estimate. But you can expect there to be several.
Black holes do exist. They are giant singularities (infinitely small compressed matter) that such pretty much everything in. They have been proven to exist and they are a very talked about subject in the field of astrophysics.
Fortunately, no. It would be pretty bad for us if there were a black hole anywhere near our Sun, let alone in our atmosphere.
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.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Carpenter bees are solid black and bore holes into wood structures. They are not aggressive in general but, because they don't have a stinger, have a pretty nasty bite.
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Black holes do not die but they can evaporate.
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
There are no black holes in our solar system
They are called "black holes".
Black holes fascinate me by there huge size on great gravitational force. The fact that light can't even get out so we cant study the center much is also pretty amazing. The thing that disturbed many astrophysicists when black holes were first theorized was the fact that the theory predicted an object that would destroy the theory that predicted it.
