Space time is made up of an inactive conductive grid, it only becomes active when energy acts on it. A second component of space time are blocks that line the grid. These void blocks, as I call them, are also made of an conductive grid much smaller and only become active when acted upon by matter. The smallest particles of matter, such as protons and neutrons, are made of extremely dense substance of space time. Their density puts a squeezing force in the surrounding space time they exist in. The force is stronger the closer to the particle. This causes a gravity field. When a gravity field touches another gravity field, the same squeezing force of space time on space time applies and the larger gravity field squeezes on the weaker one pulling it harder. Both objects then move towards each other in proportion to there weight. Electrons and energy are also a squeezing force on space-time. Electrons get caught in electron shells around atoms. They add weight to matter by squeezing on space time and giving the impression of gravity. When they convert into light there weight converts into momentum and the become a stress only on the conductive grid, not on void blocks. Magnetism is a flowing of space time and its field doesn't create gravity either. A magnet acts like a fan for the conductive grid of space, seen by the repulsion of two north or south ends. The electrons in the magnet all circle in the same direction which acts as the fan for the conductive grid.
Because a neutron star crushes matter pretty tightly and if there was more space in the atom inside the protons and neutrons, it would seem to defy laws of stress space-time can handle and its limits such as the speed of light.
Um, you've heard of particle accelerators, CERN, quarks or the Higgs Particle, right? Do you not believe in the results observed during their tests? Is that what you're saying is all "theoretical?"
