Why can't early black holes not grow by eating dark matter? No radiative pushback, but perhaps too small a cross-section? Would that depend on DM temperature and particle mass, but already excluded by candidate parameters? I thought I was trained in this business, but... 🤷🏼♂️ 🔭

Is DM a particle though?

An accretion disk forms and drives matter towards the center because friction removes angular momentum from said matter. And no electromagnetic interaction will mean there’s almost zero friction, so the mechanism doesn’t work
