It is said that anywhere from 85 to 93 % of the mass in the universe
is dark energy and dark matter. It apparently surrounds galaxies
as unseen "halos", yet no one knows what it is. Here is a wild
conjecture from an amateur cosmologist for your entertainment.
Proposed: Every galaxy has at its center at least one black hole
actively consuming matter. In the black hole this matter is
dissassembled beyond the atomic scale, beyond the scale of quarks, to
the scale of the planck length. Once reduced to this size, matter
is no longer matter, per se, but energy quanta, which exit our universe
via planck-length-sized worm-holes. These worm-holes carry the
energy, on average, a few thousand light-years before the energy
re-emerges into our universe. The energy does not recondense into
matter, gravity, or another one of the four forces because it has entered a
cold universe and can not go through the phase transitions of gradual
cooling as occurred after the big bang. It is "quenched" as dark
energy. Dark energy is, however, slowly able to condense into
dark matter. Perhaps that explains why the universe has recently
begun to increase its rate of expansion. The amount of dark
matter is increasing.
I would love to hear some comments.
