cool! so dark matter, creates dark stars, which collapse to create black holes, which suck in stars and space stuff around them? so do the xrays* emitted change back into dark matter? or do the black holes, when they ultimately evaporate, (per Hawkins) change back into dark matter?
*I’m not sure if it’s xrays I’m talking about (it can’t be light, right?), but every picture I see of a black hole has two streams, top and bottom, streaming out from the center of the hole as pictured here: http://hubblesite.org/explore_astronomy/black_holes/encyclopedia.html
That isn’t an xray that is a jet of gas. If there is a large rotating body surrounded by gas there are two main features. Accretion disc and a Plasma jet. Accretion disc sort of looks like Saturn’s rings but extend all the way towards the black hole. The plasma jet is gas from the Accretion disc that some how gains energy from the spinning of the black hole. The jets can extend hundreds or thousands of light years and are extremely fast moving and hot.
