Negative mass is required for gravity to work. What is Negative mass? Space is made from a grain structure... Brain Fractals The reason that I posted some fractals is because fractals identify physics. Dark Matter relates to fractals found in grain structures like the brain for example. Brain = Web of fractals Dark Matter = Web Of Fractals Brain = Grain Structure Space = Grain Structure In any grain structure you cannot fill all of the spaces. You have gaps. You have gaps. Energy moves towards the area of least resistance = gaps Energy moves to gaps Gravity flows into gaps in the Earth in the grain structure. Ok so a tornado is spinning, and things move towards the tornado. They move towards gaps, and suction in a grain structure. You just have to remember that you can't fill all of the gaps in a grain structure to get gravity to work. So if Earth is mass, gravity is moving into the negative mass gaps... fg = gm1m2 )/(d^2) The sum is the equivalent of the gaps in a grain structure, but the opposite physics are used. Newton worked on the kissing number problem... Kissing Number Problem It found that 12 balls will fit around 1 ball, but there is always a gap, and you can't fill it. The atom I believe is constructed in the same way. Which therefore has a suction force for gravity. Flow into gaps with more energy moving out of the container... like a bar magnet. As anything approaches a gap it often will not fit through them... bar magnets, tornadoes, suck a straw against your finger. The out flow, and the inflow are opposed, and you get spin. You get spin around a tornado, and bar magnets have internal spins created by the rotation of electrons. So negative mass are gaps in mass, and are equal to the same mathematical formula. Gravity is to move towards gaps in a grain structure, and to escape as a magnetic pole. The same applies to Black Holes. The energy can escape through gaps in the grain structure of space. Energy will scale down to escape increasingly smaller gaps. You get a red shift from contraction through gaps in a grain structure. You get the illusion of a bending of spacetime through gaps in a grain structure. Magnets attract gravity, gravity fills the gaps, the tornadoes fit to iron filings internally not externally. So it is an internal flow force that separates it from other none magnetic objects. Also the gaps rotate, which is important for some forms of physics.
