I have had an idea now for a while and am just wondering if the direction along the path of thinking that I am using is followed in any well established theorys. The basis for my thoughts is that mass/particles are ultimately vibrations of that which the vaccume of space consists of. Similar to how hot air is vibvrating more than cold air and is thus less dense than cold air, mass is vibrating and thus less dense than that which the vacuum of space consists of. Following that gravity is the result of the pressure of the surounding vacuum acting on mass. One object would attract another because there would be less of the vacuum between them and thus less presser exerted form the other objects directon. I think that this type of model may also be able to explain black holes. Heavier matter is heavier because it's vibration is more intense. As very heavy bodies becomes compacted localized vibration becomes more intense, but when matter becomes too tightly compacted, it has no more room to vibrate. At the center of the black hole, mass has been converted back into vacuum. Outward from its center mass is at maximum vibration. I know that this is highly imaginative, I'm not trying to advertise my own theory, I'm just wondering if there exists any credible theories that attribute mass as vibrational energy?
