Could gravity be more of an effect than a cause? Let's say that the fabric of space is like neutrinos, near mass less. Neutrinos were theorized then later proven when they were converted to energy.
Whenever they show Einstein's theory of warped space they show a sphere laying on a cloth with grid lines. The cloth and grid lines are bent or warped by the weight of the sphere. Even though it's a 3 dimensional picture it's still a 2 dimensional depiction. Now if you had a picture of a sphere and lines of the fabric pinched in at 64,800 degrees that would be 3 dimensional. Now the warped lines would be warped tighter according to the mass of the sphere rather than the size of the sphere. So a neutron star would have a stronger pinch or range of pull than our sun which is much larger. It's accepted that if you place two small objects near each other in space they will eventually come together as long as there are no outside forces. Could this near mass less fabric be so large that it could be the dark matter that has eluded physicists for so long?
