From Osher Doctorow
We can unify expansion, contraction, repulsion and attraction as
follows:
1) repulsion and expansion are the same process (in sometimes
different scenarios)
2) contraction and attraction are the same (same qualification as
above)
At the same time, we are enabled to unify electrostatics at least but
also parts of electrodynamics with spacetime cosmology and
gravitation.
Two positive charges or two negative charges repel, while opposite
charges attract. This can be explained as expansive behavior but
also the nature of charge changes in our theory to a phase-tendency.
We are seeing actual expansion versus contraction in practice - a
present-day laboratory into the past changes of the Universe.
What, then, explains the fact that we only see uncharged masses
attract as in gravitation? But this is precisely what appears to
have changed with the acceleration of the Universe. Uncharged masses
are now predominantly not attracting but repelling - at large enough
distances. Whether there is also an overabundance of interacting
charges of the same type is another question. Probabilistically, it
is possible.
The confinement of quarks in hadrons is arguably an analogous
contraction at large enough distances for quarks, unless somebody
finds a barrier from which they repel "inward" (which would also be a
type of contraction from boundaries - a possibility even on certain
cosmic scales or scenarios).
