Meta-cold dark matter

Meta-cold dark matter, also known as mCDM, is a form of cold dark matter proposed to solve the cuspy halo problem. It consists of particles "that emerge relatively late in cosmic time (z ≲ 1000) and are born non-relativistic from the decays of cold particles".[1]

gollark: `sudo -i` and do whatever it is?
gollark: Racks are for putting multiple things in.
gollark: You could convert the internals into some sort of tasteful art piece.
gollark: What compatibility? They both support x86 + a pile of extensions do they not?
gollark: And probably a better upgrade path.
