Firstly like poles i.e. two north poles repel. [/quotes]Oops. Sorry. I don't know what I was thinking.Quote from: jeffreyHSecondly the positive charge comes from the proton and not the electronSo what? Who was talking about charge? And what charge are you talking about?

Secondly the positive charge comes from the proton and not the electron

Quote from: jeffreyHThe poles of a magnet may be seen as a convergence of both the electromagnetic and gravitational fields.The magnetic field does converge at the poles of a magnet, but not the gravitational field.Quote from: jeffreyHOpposite poles would consist of one electromagnetic and one gravitational field.A gravitational body does not have opposing poles.Quote from: jeffreyH Both virtual photons and virtual gravitons would be involved. Like poles repelling.The like poles of a magnet attract. They don’t repel.

The poles of a magnet may be seen as a convergence of both the electromagnetic and gravitational fields.

Opposite poles would consist of one electromagnetic and one gravitational field.

Both virtual photons and virtual gravitons would be involved. Like poles repelling.

Could it be that instead of opposite poles, gravity could be composed of opposite forces, and that what we feel as gravity is really the net difference between the two forces?

A photon may not follow a geodesic path near an event horizon but would curve away. It would ultimately end up at the poles where rotational velocity is less and it has no option but to leave the vicinity as a relativistic jet.

It would ultimately end up at the poles where rotational velocity is less and it has no option but to leave the vicinity as a relativistic jet.The only interaction acting on photons is the gravitational interaction. Therefore all photons follow geodesics.

A geodesic is the shortest path.

Quote from: jeffreyHA geodesic is the shortest path.Not really. A geodesic is a path of extremal length. For example: A great circle is the curve defined by the intersection of a plane which passes through the center of a sphere. Think of yourself and two friends on such a great circle on the earth. One friend is 1 mile away on the great circle while the other is on the opposite side of the earth. A path to each friend is a geodesic. But one is obviously much shorter a distance than that other. So think of geodesics as paths of extremal length, not shortest length. This happens in curved spacetime too.

Could we have gravity without time? Could gravity just have spatial dimensions without acceleration? Minus time as a dimension could we have three dimensions and an extra spatial dimension? What would that do to Maxwell's or Einstein's equations?

Could the change occur as an interaction with another dimension, not time, that causes a displacement of 3-Dimensional space?

If we want to travel the vast distances we know exist we need to come up formulations where time goes to zero. The possibility of such formulations seems an eventuality, all it takes is someone with the right imagination.
