Do black holes move or are stationary in space?

Answer 1

Many correct answers regarding ordinary blackholes so far. But even supermassive blackholes at the center of most galaxies move as the entire galaxy move. Galaxies are bound gravitationally to the other galaxies in its cluster. The Andromeda galaxy is moving towards the Milky Way for instance. And the cluster itself is moving as the universe is expanding. In short: there is no such thing as "stationary" in space.

Answer 2

Partial solutions of the Einstein equations point to two possible outcomes: -A non-rotating, spherically symmetric black hole, first postulated by Schwarzschild. -A rotating, spherical black hole, predicted in 1964 by the New Zealand mathematician Roy Kerr. These two types of black holes have become known as Schwarzschild and Kerr black holes, respectively. Both types of black holes are "stationary" in that they do not change in time, unless they are disturbed in some way. As such, they are among the simple st objects known in General Relativity. They can be completely described in terms of just 2 numbers: their mass M and their angular momentum J. Keywords being:"angular momentum" Nothing in space is stationary. More importantly, the Milky Way Galaxy will be colliding with M31-- the Andromeda Galaxy ...eventully (some 3 billion years from now)

Answer 4

Do Black Holes Move

Answer 5

There no such thing as stationary in space. Everything is moving with respect to everything else, So if a space ship (for example) has a different velocity than a black hole, the black hole flying past the space ship is just a valid as the space ship flying past the black hole.

Answer 6

Black holes are not stationary. They move through space, and most of them rotate as well.

Except for the giant black hole at the center of the galaxy, they are all moving around. But everything in space is so ridiculously far apart anyway that they're not gathering "everything" up. Black holes have no more gravity than any other large star, they are just more compact (infinitely compact, actually).

Answer 8

A black hole is subject to the same gravitational laws as other bodies -- it attracts other masses, and it is attracted by other masses.

For instance, suppose a star becomes a supernova and then a black hole. If that star was orbiting about the center of the galaxy, then the black hole will also orbit about the center of the galaxy. (If the explosion was asymmetric, however, the black hole would have a different velocity than the star did.)

Also, remember that momentum and angular momentum have to be conserved. Whatever momentum was in the original star will subsequently be split between the black hole and the ejected matter.

Answer 9

Everything is moving. Besides....if a BH was stationary, stationary to what?

Remember, the universe keeps on expanding and expanding. We're all moving with it.

Answer 10

A black hole will move through space in the same way that the star it formed from moved. However, they do not go 'hunting' for new things to devour.
