Would it be possible in an imaginary matrix i , for the internal energy of the matrix i , only be positive in polarity? Wheres the gravity? Wheres the strong nuclear force? Where is the electrostatic binding force? My conclusion, is that the matrix would disperse by repulsive force? The dimensions of matrix i : Previously, the best measurement of the diameter of theproton was 0.877±0.007 femtometers (m) and this measurement measured it to be 0.8418±0.0007 fm. A femtometer is 10-15 meters.
