How many Gs does the average black hole generate?

Answer 1

Because black holes are invisible (they emit no light of their own), they are difficult to see. Scientists have never POSITIVELY identified a black hole, and it is unlikely that we will be able to do so any time soon.

However, the math and physics of a black hole also describe several indirect methods of deducing the presence of black holes, and scientists have located a number of objects in the galaxy which appear to be stars in the close proximity of a black hole.

So far, there is no way to be certain, but black holes are believed to exist near the centers of virtually all galaxies.

Answer 2

It is unknown. NASA estimates that there may be anywhere from 10 million to 1 billion black holes in our galaxy. The other 100 billion or so galaxies in the known universe likely have similar numbers of black holes.

Answer 3

Nobody knows.

ignore the first answer.... because actually, there have been 2 black holes discovered within our galaxy. scientist have watched a star disappear either by going into the hole...or going behind it. we will never know for sure though, because the star is outside our range. but there is a gap of 24000 light years from planet earth to the hole. so we should be fine for a while. :)

Here you find a few, and a link to more information:

Actually, I would guess that only a tiny fraction of black holes has been found, even in the neighborhood - a black hole is only likely to be found if it is part of a close binary, i.e. it has another star very, very near, so that the black hole regularly gets matter from the other star.

Answer 5

There are probably billions of black holes in the universe. While it is not possible to directly detect a black hole, the indirect evidence of a high gravity point source with x-rays being emitted as matter falls into it is a fairly sure sign. By that measure, we have solid evidence of several black holes, and suggestions that indicate that supermassive black holes probably reside at the center of many or most galaxies.

Answer 7

All black holes, no matter what size, generate infinite G's of gravity.

Answer 8

Most galaxies have a supermassive black hole at the center and millions (at least) of stellar mass black holes.
