Giant monopoles as a dark matter candidate

[Chronos]

This paper, http://arxiv.org/abs/1311.1627, discusses the possibility of giant monopoles as a dark matter candidate. It is not a 'new' idea, it dates back to Dirac's giant monopole concept. In this case, the author suggests the 't Hooft-Polyakov monopole, which avoids the singularity problem of the Dirac model. One of the most remarkable features is it solves the Milky Way satellite problem that plagues the WIMP model. It is also consistent with observations over cosmological distances. I thought it was quite interesting with some far reaching implications. It certainly looks like a supersized quantum solution to the elusiveness of dark matter particles.

Wow, that's a really interesting read.
