there are only expansive forces in the universe and mass-related contracting forces. the universe's expansion, time, the inertia of the planets and electrons, the photon scatter out of stars on the one hand. the tug of a black hole, of gravity, of an atom's nucleus on the other.
does it altogether matter what we call these opposing forces as they express themselves throughout nature?
this is all that we are. it is everything we think. it is every kind of variation we experience.
