Yes. If you mean Sagittarius A*, its mass, and even more so its diameter, is only a tiny fraction of the mass, or diameter, of the Milky Way.
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.
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.
It's theoretically possible for a black hole to be larger than the Milky Way, but as far as we know, most are much, much smaller both in mass and extent.
Yes. It's physically impossible for anything to be smaller than a 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
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.
No. At least, the black holes in existence so far are much smaller in size, and have much less mass, than a galaxy. However, note that the black hole in the center of the largest galaxies can have more mass (but not more diameter) than some dwarf galaxies.
There is no such thing as a black hole with the mass of a galaxy. At least, none that we know of, and not if you are thinking of a large galaxy like the Milky Way. The largest known black hole has about 20 billion solar masses - which is still much less than the mass of a typical galaxy. For example, our Milky Way is estimated to have a mass of about 700 billion solar masses. However, such as massive black hole does have a mass comparable to smaller galaxies, i.e., dwarf galaxies. In any case, such huge black holes are found in the center of large galaxies.
If you are talking about a black hole, then you get squished into a ball smaller than an atom and keep going, or time can change.
It depends. Most black holes are indeed smaller than Mercury, but asteroids vary widely in size. The radius of a black hole's event horizon is directly proportionate to its mass. The largest known stellar mass black holes have about 15 solar masses, which gives a radius of 44 kilometers. This is larger than most asteroids, but some asteroids are larger. It is much smaller than the planet mercury. However, supermassive black holes are far larger than mercury. An 830 solar mass black hole would have an event horizon about the same size as Mercury. The black hole at the center of the Milky Way has about 4 million times the mass of the sun, giving it a radius of over 7 million miles, or 17 times wider than the sun's radius. The largest known black hole is about 40 billion solar masses, giving it a radius of more than 70 billion miles, making it larger than our solar system.
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.
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.
