I would like to join in with many of the statements in this thread describing a joint lack of understanding of the physical universe as well as a deep fascination with it. I certainly count myself among those ranks.

In watching way too many YouTube videos on quantum physics and gravity I began to create a model of how the universe works at the very small scale and after a while something occurred to me.

We know that the path of a photon can be bent if it passes near a black hole. The key being that spacetime is being somehow consumed by a black hole and the photon is being dragged towards it. Thus, its path appears bent. I thought that similar effects should happen with volumes of a lighter mass. Perhaps with the same mechanism.

Neutron stars would have a smaller effect on photons, and a more measurable effect on heavier particles and molecules. Neutron stars would also somehow 'consume' spacetime. Just at a lower rate. Thus heavier particles would escape.

So too with the earth. Only, in this case, the mass of the earth is small enough that molecules can escape all on their own.

So, what is gravity? Gravity in this model is the effect of spacetime being consumed. By analogy the spacetime is like standing under a shower. We are glued to the earth because we cannot gain enough purchase against the torrent of spacetime being consumed by the mass of the earth.

Which brings me to the second question. Well, this is where actually having some physics would be useful. But after many drunken bouts of thought, I'm convinced that this spacetime consumption is down to [color confinement](https://en.wikipedia.org/wiki/Color_confinement#QCD_string).

Anyway, enjoy. If nothing else, this should at least be useful for some sci-fi anti-gravity mechanism.
