First up, I am not a physicist (just a meek mathematician and engineer). I was watching a television show last night on Discovery Channel, where they were summarizing and simplifying the current train of thought in cosmology. Therein, the expounded how dark matter is needed to hold spiraling galaxies from spinning apart.
Then I struck me that perhaps a revised equation of gravity (Newton's inverse square law) might be able to also explain the observed "adhesion" within the galaxies. Here is the idea:
- The force of gravity, F.g, which is holding galaxies together is stronger than Newton's equation (F.g=G*M1*M2/r^2) but only over large distances, when r is of the magnitude of galaxies. So, 1/r^2 term would be replaced by some polynomial that doesn't deminish at the same rate as 1/r^2, such as [C/r + 1/r^2] where C is a constant.
- The centrifugal force, F.cf, which is trying to fling the galactic stars out of their orbits, remains the same, as per classical mechanics, F.cf = d(M1*V)/dt
- The centripetal force, F.cp, which matches gravitation force would remain the same, as per classical mechanics, F.cp = M1*V^2/r.
OK, please critique my conjecture.
