Dark matter...i think i know what it is...check it out

  Do you have a point that your are trying to make.  As it seams the only thing you do is to argue.

Science is all about arguing, what's your point, I argue on the side of the winning hand of science, nothing else. fact is all there shall be in the end.

  My point is that you are so absolutely right, that you can just keep right on arguing,  but not with me.

the best way to envision the ongoings of galaxies within the universe

is to fill a tub with water
and scatter several tiny styrofoam spheres into the surface
you only see interactions on a 1-dimensional plane, but it gives a good visual.

forces between different galactic bodies, their own inner forces,
rate/direction of spiral, velocity/trajectory, momentum, electric field

all these things play a part in determining the direction of each galaxy and how it interacts with its neighbors, and in some cases, with galaxies far far away.

comparing light to sound:in space where there is no air(the very substance of sound)there is no sound.so sound is in fact variations of densities in the medium which it is moving through.when this principle is applied to light,that is to say if light were sound then the light would be in fact made up of the medium which it is moving through or compressing and expanding.think of the universe as "filled" with this "air" or use the idea of water if it is easier for you.what i am saying is in fact that the universe is the medium through which the light is moving,compressing and expanding.and the speed of light is defined by the density of this medium.the implication that light has a constant speed as a law is ridiculous.the light is subject to density just as sound is subject to density when it moves through water or air.the mistake is to assume that there is no medium(or that space is empty).think of the medium as a "space" with it's own frequency reacting with consonance or dissonance with whatever happens within it.if you add sound to sound in water or air it doesn't make the sound move any faster.if light is moving through a medium it explains why light can be seen as a particle and a wave...light is the particle and the medium is the wave.and if you haven't thought of it yet:this implies that light does not exist in and of itself...it depends on this medium just as sound depends on air.zero rest mass is a concept that wrongly describes something that does not exist...that is to say that sound or light that isn't moving in fact does not exist,that which has not affected anything cannot be(a cause).light is evidence of the constant density of the universe:just as sound is evidence of the constant density of air or water.

Possibility of Sound Propagation in Vacuums with the Speed of Light (Electron-neutrinos fit the properties of vacuum-sound waves).

QUOTE=Page 7
"Thus, these sound waves should interact negligibly with matter of normal density, e.g. air, due to the high ratio of the phase-velocity of sound propagation in a vacuum and in air of approximately 10^6 and because of their very short wavelength which is smaller than double the lattice-spacings of normal materials."

QUOTE=Page 8
"Furthermore, neutrinos are emitted only from matter of nuclear or even higher density in which the speed of sound approaches the speed of light.  They also have very short wavelengths due to their generation in high energetic, nuclear processes (neutrinos are, in a sense, the γ-quanta of sound) which causes them to be transmitted through materials of normal density."
