No. The most massive black hole we have evidence for may have a mass of about 40 billion suns. This mass would give it an event horizon about 60 billion miles across, which is tiny compared to even the smallest galaxies.
No - The volume of the Milky Way galaxy is larger than the volume of its host black hole. The accumulated mass of the Milky Way galaxy is greater than the mass of its host black hole. The density of the Milky Way galaxy is much smaller than the density of its host black hole.
the centre of the milky way is believed to be a super massive black hole .the black hole, said to be 27000 light years from the earth, is 4 million times bigger than our sun .It is believed that almost every galaxy have a super massive black hole as its centre
Most identified black holes are much smaller than the Milky Way. If there was a black hole the mass of the Milky Way (which is probably 100,000 light years across) it would only be about 2/5ths of a single light year in width. Even the largest known black hole is much smaller than our galaxy.
I don't think that either of these stars "have" a black hole.
There are loads of black holes in the Milky Way Galaxy. The closest is only 1,600 light years away. The largest is at our galactic centre. A super massive black hole, with a mass greater than over 4 million solar masses or over 4 million times bigger than the sun. Black holes are resulte of a defomation in space created by a very compact mass.
Maby the universe
The quasar is bigger. A quasar is a disk of superheated matter that surrounds a supermassive black hole. The mass of the black hole may be greater than that of the disk, but it is compacted into a smaller space.
Good question - The black hole(s) (i.e. Sagittarius A*) at the center of the Milky Way are estimated to be a little more than 4 million solar masses (e.g. stars like our Sun). The Milky Way galaxy is a barred spiral galaxy 100,000-120,000 light-years in diameter and has been estimated to be hosting 200-400 billion stars, and at least as many planets. Therefore the answer is that the accumulated mass of the Milky Way galaxy (of course excluding its centric black hole(s)) is greater than the mass of the black hole(s) at the center of the Milky Way.
Black holes can be many different sizes. Therefore, there are some black holes that are bigger than the sun, and there are some that are smaller than the sun.
Yes. A quasar is a disk of superheated material that sour rounds a supermassive black hole.
Yes, a black hole is usually a star that has been compressed to a point where the density is really high.
No. The Milky Way is our Galaxy.
