I am saying that when you get more energetic matter together the gravitational attraction increases. Matter, as I see it, is all that is, including antimatter and every other kind of particle imagined because at the core, it's all just one particle, just operating at a different energy level. The energy level = the properties of the particle which of course changes it's wave that it creates. So it is interpreted as a different kind of particle. Matter is sorted in the universe according to it's energy level. High energy particles cluster to form a gravitional cluster, even if it is just two particles, while low energy particles or say, negative energy particles, if you will, do their part by, at the same time, repell the high energy particles. The planets/stars are composed of high energy particles clustered together while inbetween, the dead space, whatever kind of particles you want to call it, is low energy particles. Like heading towards the sun, the closer you get, the higher the energy of the particles you encounter. That's probably not put in my best terms but maybe it will help.
Ok, I didn't have the best punctuation going on there but it's best to imagine a universe full of particles with a pressure likened to the sea. I know, because of the properties of outer space, we don't think of pressure in the universe, but it is, just like we don't feel much pressure in the air but there is. It's varying degrees. I just imagine a sea of particles in a pressurized chamber all sorted, or attracted, by the energy in which they carry. And to clarify again, let me state, high energy particles attract the like, and repel the opposite, same with low energy particles. And there is no two states, there is varying energy levels between the states. Such as the gravity level in outer space, but close to the earth. And outer space has we know has low pressure, hence the very low energy particles in space. But light can move through it because light is a very high energy force. So high but so small a photon is, that it projects a beam through low energy particles such as space. Like a quick punch, it hits particles with a very high pressure, which speeds more particles in it's direct path, like how electricity works, somewhat.
