What do galaxies revolve around?

Answer 1

There is no known center of the Universe. It is believed that on a large scale, all parts of the Universe looks the same; wherever you are, it LOOKS as if you are at the center (distant galaxies will be receding from you). This is called the cosmological principle.

Answer 2

Galaxies float freely in space. They are attracted to each other gravitationally, causing clusters of them, but only in a dance of collision do they orbit each other.

At the center of spiral and bar galaxies though, there are usually supermassive black holes of which the matter in the galaxy revolves around.

Answer 3

As our telescopes improve, we have discovered that there are supermassive black holes in the cores of many, perhaps most galaxies. Scientists have long known that the galaxies did not appear to have enough mass to stay together; since they DO stay together, there has to be mass - a LOT of mass - that we aren't seeing.

Many theories concerning "dark matter" exist; the question now is, is the black hole the "ultimate" form of dark matter, or is there something more?

Answer 5

Interesting question. Is the sun spiraling in to the core, where a massive black hole awaits, devouring entire stars, or will it spiral outwards, and end up lost in the dark intergalactic void? Or, will it simply continue to revolve some 30,000 light years out from the galactic core, on its 220 million year journey, until all the stars fade away into dark cold dying embers, and space has expanded so that the nearest galaxies beyond what has become our local group are undetectable?

Cases can be made for each scenario, but no one can give you a real solid figure, as the answer is as yet unknown.

Answer 6

Yes. All the stars visible to the naked eye are in a fairly small portion of our galaxy.

Answer 7

In roughly circular paths that go in the same direction in roughly the same plane.

Answer 8

the gravitational pull of other disk stars always pulls them toward the disk

Answer 9

No - galaxies are moving away from each other... The universe is still expanding from the Big Bang.

Answer 10

Yes, many galaxies rotate around a center or core. The majority of all of the known galaxies rotate around a core.
