Is this a possible theory?

Question

What if farther into the Milky Way Galaxy, there was a huge star, far greater than the sun's mass, and it pull everything in the Milky Way towards it, and made them orbit. What if the sun was a planet orbiting that huge sun, and the planets were the moons of the sun? Would this ever be feasible? But since the huge star is so far away the sun doesn't seem to move. Do stars move by gravity? If so I think this could be a plausible idea. Please if im totally wrong and nothing makes sense keep the critizism to a minimum.

Answer 1

This is similar to what already is the truth. The supermassive blackhole in the center of the galaxy is like the sun in our solar system in that it has objects orbiting it; and there are other objects orbiting those objects. And so on.

In short, there is a lot of orbiting going on from galatic superclusters all the way down to quarks and electrons.

Answer 2

The Milky Way galaxy also spins otherwise everything would fall to the center of the galaxy. Suns and stars are generally defined as heavenly bodies that can support fusion of hydrogen and emit vast quantities of energy. Planets are much cooler and do not emit light (although the giant gas planet Jupiter is almost massive enough to be a small star). Moons orbit planets and the earth's moon is the largest relative to its host planet's size. Personal 'theories' often present an opportunity to explore and learn (been there done that!).

Answer 3

A lot is known about the Milky Way---whole libraries on the subject. The Milky Way contains about 10 billion solar masses of material. Most of this is Dark Matter, lots of it is stars, and some is dust and gas. There is a moderately-large Black Hole (3.6 million solar masses) at the center, and some smaller black holes elsewhere within the galaxy.

All this material orbits around each other---there is no single, dominating mass. It's like a swarm of bees---each object orbits around the distributed mass of all the other objects. The gravitational potential well is not shaped like the one in our solar system---it is more flattened, and deeper. The orbits in such a potential well are not like the orbits in the Solar system. The orbits are not closed, in general, and stars bob up and down out of the disk of the Milky Way as they go around.

Answer 4

hmm the milky way is a system which moves along a almost circular path... earth revolves around the sun and the moon around the earth the milky way also revolves around something which is actually theorised to be either a big sun (which is quite plausible) or a black hole type which personally i don't really think is relevant... something else except from moving in an eliptical way around the galaxy we also go up and down in our motion... so basically you are kind of right... but then all starts act on gravitational centripetal and centrifugal forces so we are in a continuous dynamic state as are all other stars and the greatest force involved is gravitational with centripetal...

Answer 5

There are many stars that are many many times more massive than the sun, The problem with this theory is that the greater picture of the whole galaxy is it is moving in unison with a greater gravity than even the most massive stars,, So we are in an arm of the galaxy and there is no chance that a massive star would pull us into its gravitational pull because the gravity as a whole in the galaxy is much stronger than the most massive star,, interesting theory though,,

Answer 6

Other posters have correctly answered that the super massive black hole at the center of the galaxy meets a lot of your ideas. Actually there is something considerably bigger and stranger: The great attractor. Heres a wikipedia blurb:

Great Attractor

The Great Attractor is a gravity anomaly in intergalactic space within the range of the Centaurus Supercluster that reveals the existence of a localised concentration of mass equivalent to tens of thousands of galaxies, observable by its effect on the motion of galaxies and their associated clusters over a region hundreds of millions of light years across.

These galaxies are all redshifted, in accordance with the Hubble Flow, indicating that they are receding relative to us and to each other, but the variations in their redshift are sufficient to reveal the existence of the anomaly. The variations in their redshifts are known as peculiar velocities, and cover a range from about +700 km/s to -700 km/s, depending on the angular deviation from the direction to the Great Attractor.

The first indications of a deviation from uniform expansion of the universe were reported in 1973 and again in 1978. The location of the Great Attractor was finally determined in 1986 and lies at a distance of somewhere between 150 million and 250 million light years (the latter being the most recent estimate) from the Milky Way, in the direction of the Hydra and Centaurus constellations. That region of space is dominated by the Norma cluster (ACO 3627)[1], a massive cluster of galaxies, and contains a preponderance of large, old galaxies, many of which are colliding with their neighbours, and/or radiating large amounts of radio waves.

Attempts to further study the Great Attractor and other phenomena are hampered due to line of sight obstruction by its location in the zone of avoidance (the part of the night sky obscured by the Milky Way galaxy).

Your big star now seems a little small, doesn't it?

Answer 7

A star could never be massive enough to keep a whole galaxy in check like that. 100 times the mass of the sun and it constantly blows itself apart. There is, however, a supermassive black hole in the center of our galaxy as in most galaxies. Black holes used to be massive stars and can gobble up matter to get any mass. Ours is probably many millons times more massive than the sun. Everything in the galaxy is gravitationally bound to it.
Stars are as affected by gravity as all other matter. Our sun is orbiting the center of the galaxy. One revolution takes in the neighbourhood of 250 million years. If the solarsystem were to stop in its tracks we would all begin to fall towards the center kind of like how the space shuttle begins to fall down towards earths when they ignite their retro thrusters.

Answer 8

Everything moves by gravity. Your theory is, though a little simplified, nearly accurate. The giant star you refer to is simply the collective gravity off all the stars in the galaxy pulling each other closer together. This is offset by inertia which keeps all the stars and planets moving. But essentially you're on the right track.

I would recomend reading the book Cosmos, by Carl Sagan. It's a bit outdated and chock full of Sagan's personal philosophies, but the basic science in it is still accurate and it goes surprisingly in depth compared to some of the simpler books available.

Answer 9

It is now believed that in the middle of every galaxy, there is a supermassive black hole.

Supermassive black hole is just a very dense but tiny object, with large gravity force

It's not exactly a massive star, but it is an object with great mass.

Answer 10

At the center of the Milky Way there is this huge mass of energie called a quasar around which the arms of our galaxy rotate but very slowly.Our galaxy is constanly changing and shifting like everything else in the universe, in a continuous motion.So yes, this theory is very plausible :)
