What are some questions about gravity that we still haven't answered?
Things like what is the mechanism which causes it and how to create a quantum theory of gravity.

Why does gravity acts as only an attraction force? Gravity acts as a monopole, a hypothetical particle. If a monopole was ever created, I assume the first test done with it, would be to test it's ability to bend light.

0. The behavior of matter under extreme pressures, like at the center of a neutron star
1. The behavior of gravity at the event horizon of a black hole. The theory comes up with all sorts of infinities that can't be eliminated. In principle, we could examine a black hole closely to get some answers on this one.
2. The behavior of gravity at the singularity at the center of a black hole. We know of no way to answer this one.
3. The behavior of gravity at a ring singularity in a rapidly-spinning black hole

It's an odd monopole that attracts its own kind.
The unanswered questions are why gravity sucks, and how.
Suppose a graviton travels from A to B. We know that B moves towards A, but how does B know where the graviton came from? And why does A simultaneously move towards B? And why is there no "graviton shield"? Any matter we place between A and B only increases the gravitational force on both. A particle model just doesn't work.

You may be thinking of a magnetic monopole? This is a hypothetical particle for which we have no repeatable evidence.
See: https://en.wikipedia.org/wiki/Magnetic_monopole
However, we do have repeatable proof of electric monopoles (eg electrons and protons).
And we do have repeatable proof of gravitational monopoles (eg the Sun). The test to see if the Sun would bend light was done by Eddington in 1919. It was one of the first proofs of Einstein's General Relativity.

A hypothetical gravitron is massless and transects a wave. Gravity between A an B is a spiral wave. Its tightness is dependent on the mass equilibrium between A and B. A loose spiral is indicative of a free fall. A tight spiral is indicative of mass equilibrium between A and B. A Lagrange point is indicative of equilibrium. As a massless particle, a gravitron is not subject to a wave but actually creates the wave parameters.

Yes exactly, a hypothetical monopole particle, it would only attract. It would exhibit the same property as gravity. As such it would be important to establish it's potential to alter wave functions. In ex: It would also be useful to see if diametrically opposed monopoles, negative and positive would cancel each other out or act as a gate.
