A good question is why a galactic plane in the first place and not just spherical galaxies? It is almost like 3-D gravity spheres have a limiting size, and then the geometry goes to less to than 3-D toward 2-D.

 

When a force lowers potential, energy is given off. This occurs with the EM, weak and strong nuclear forces. But is not evident with gravity. Therefore, one can conclude either gravity is not a force, like the other forces, or the energy given off, as potential lowers, is not as obvious as the other three forces.

 

If gravity was a force and the lowering of gravity potential gave off energy, like the other forces, even if we could not see it, there would have to be some related energy intensive dynamics occurring that reflects the amount of invisible energy given off. Rotation appears to one such dynamics. It takes energy to get this into motion, while avoiding the direction of gravity (resistant to gravity).

 

One simple way to explain the source of this invisible energy is connected to entropy. A large gas cloud has X amount of entropy within all its disorder. If gravity was to act on this cloud, to compress the mass, the degrees of freedom within all the material is reduced, therefore entropy lowers. Since the lowering of entropy will give off energy, one would expect the exothermic entropy output, will have an impact on other entropy.

 

A rotation will give more degrees of freedom, since the mass is able to occupy more space than within a static ball. This directional entropy, requires energy to occur and resists the linear direction to the center of gravity, by using the other 2-D. If we add tilt, like the earth, the degrees of freedom increases further since the mass is able to occupy even more space. This suggests an even higher initial lowering of entropy to get that into initial motion.

 

Is the energy output of lowering gravitational force at the level of entropy, being reflecting in entropy instead of energy quanta? Once we go into orbit around the earth and enter the entropy field, we can avoid gravity, i.e., zero gravity even with all that mass just sitting very close by. The motion-entropy mathematically adds up to negative gravity (net equals zero) which would be the expected energy output of lowering gravity potential.

HydrogenBond,

 

Your post makes no sense and is unrelated to the topic.

Please refrain from doing this.

The topic is our galactic plane. The question I asked was, why is the milky way galaxy, like most galaxies, spread into a 2-D plane instead of a 3-D sphere? If a galaxy started using a center of gravity, within a large spread out mass, gravity will act in 3-D from the center of gravity, and the galaxy should form a sphere. But instead, the mass begins to circulate toward a 2-D plane, avoiding the original 3-D impact of gravity.

 

One simple way to explain this is, the other three forces of nature, when they lower potential, will give off energy. The energy that is given off will create an effect that looks like the anti of that force. For example, if an electron drops energy level it gives off a quanta of energy. This energy output can impact another similar atom to reverse the EM force.

 

If the lowering of gravity potential is the lowering of a force potential, one would expect an exothermic output. This output should create an effect that looks like an anti-force, which in this case will look like anti-gravity. Moving away from the original 3-D radial movement toward the center of gravity, toward a 2-D galaxy plane. This is consistent with the exothermic output of gravity, past-present, giving off energy potential that creates what looks like an anti-gravity effects, such as rotation, orbit and 2-D planes, all of which resist 3-D gravity. ertr

 

Entropy is not anti-gravity in the sense of anti-relativity or anti-gravitons, but it can zero out weight or the effect of gravity on mass. I like the term entropy better than anti-gravity to avoid confusion with other concepts, while leaving it wide open.

So, it seems you are questioning why most galaxies are counterintuitively spiral (or disc) shaped rather than globular, and then you propose an answer. Did I get that correct?

Yes. If we start with a center of gravity, one would expect gravity to pull the mass in radially, since this is the shortest path for lowering the potential. But instead, galaxies begin to rotate, so the mass will take a longer path contrary to the initial 3-D optimization. Observation shows the initial 3-D optimization will start to move toward 2-D. This can be explained with an exothermic output stemming from gravity, with different energy outputs causing the various shapes.

 

Although not a galaxy, the earth shows a slight shift from 3-D gravity optimization toward an equatorial 2-D plane; bulge. This I would equate to the exothermic output of the gravity during earth formation. This simple model allows one to infer the formation dynamics from the final shape; faster acting gravity will generate more energy output and will create more entropy. Spiral galaxies show more motion in 2-D and would be indicative of fast forming galaxies, with the fastest gravity formation events making the most turns, since this is most energy intensive (requires the most gravity energy output)

 

I inferred this theory from the observation that the other three forces will give off energy when they lower potential. If gravity is a force, it should also give off energy when gravity potential is lowered. This is not obvious, since nobody thinks in terms of gravity giving off energy when it lowers potential. But galaxy geometry toward 2-D and motion, shows energy at work, with gravity the only source big enough to account for it.
