 | Is there any experimental evidence to show that the gravitational field generated by a particle is actually uniform in all directions?
Magnetic fields have directional components that make them stronger in some directions than others. Is it possible that gravitational fields have similar properties, but the effect is never noticed because the particles of matter are randomly organized just like the magnetic fields in non-magnetized matter?
There could even be directions where the gravitational field generated by a particle is a repulsive force instead of an attractive one. Something attractive on an xz plane, but repulsive on the y axis or something.
I've seen in a couple books that the force of gravity is smaller than it seems like it should be. Would something like this remove the need for parallel universes smashing together?
Disclaimer: I'm not a physicist. I'm just an amature with a math degree and a lot of interest in the field.

There is no possible arrangement of dipole, or any higher multipolarity, fields which can simulate a monopole field, since the multipole functions are an orthogonal set.

This is because there are no magnetic "monopoles" only dipoles. N and S are paired. The lines of force can be traced by iron filings for example. On the other hand, charge and mass exist as monopoles, which do have the direction uniformity if the sources are treated as points.

"Parallel universes smashing together?"
