From: BURT on
Albert Einstein thought atoms contain a concentrated energy. But point
particles have a center point of mass that is infinitely dense energy.
Surrounding mass is unconcentrated energy that is associated with the
bond field of the electric and strong forces. The bond energy in the
atom is finite denisty of energy that is spread out in the field. The
atom bonding forces are unconcentrated energy when bound and empty of
energy when not.
