MagHydrogen as Dark Matter?

[stevebowers]

In cosmology, one candidate for dark matter is monopolium. This is usually imagined as a monopole/antimonopole pair, but if the sort of charge relationships that we imagine for magmatter are possible, then we can consider magmatter as a subset of the possible types of monopolium. There have been a number of studies of the prospects of monopolium as a dark matter candidate, so we can look at them to see how they measure up. Unfortunately, these studies mostly conclude that monopolium, as a tiny, dense, neutral particle-pair, would be very tricky to detect. We would have more success with trying to manufacture monopolium than detecting it in its naturally-occuring state - although some very high energy cosmic rays might be emitted by decaying monopolium dyads.

One thing that strikes me is that every star should have a small but slowly increasing amount of maghydrogen at its heart. The particles would not be significantly slowed by friction with normal matter, so they wouldn't accrete in the same way that ordinary hydrogen atoms would- but gradually, over time, magatoms would interact with each other at the heart of a star and form a small nucleus. When this nucleus reaches the critical density it will become a black-hole- eventually absorbing the whole star (probably far in the future, long after the star becomes a black dwarf).
