My intuition says that this search for dark matter is going to turn into a wild goose chase like the search for ether. Surely, if dark matter existed we would have seen a bit of it already in our particle accelerators. I suspect that Newton’s law of gravity is not quite true.
- F is the force between the masses.
- G is the gravitational constant.
- m1 is the first mass.
- m2 is the second mass.
- r is the distance between the centres of the masses.
It could be that larger masses have a bigger effect that you would expect from linearly extrapolating small ones. It could be that gravitational effects fall off slightly more slowly than Newton predicts. These effects would look like extra unexplained mass at large distances. Keep in mind that I am a rank amateur when it comes to cosmology. I am just hoping for a lucky guess I told you so.~ Roedy (1948-02-04 age:70)
I have since learned, they are pretty sure my idea is wrong.
