What if we are looking at it backwards?

Rather than gravity as a property of matter, what if there is a centripetal dynamic going from the barest bending of the light, to the vortices at the center of galaxies, with matter as an intermediate effect, that appeals to our tactile sensibilities.

So we put matter at the center of the model, like we once put earth at the center of the model.

When waves synchronize, the effect is centripetal. Lasers are synchronized light waves.

When we really study matter, it seems more positive and negative charge, than any actual little things.

Here is someone who saw it as waves all the way down;
