Black Holes ARE Dark Matter?

Dark matter could be almost anything.  With little data other than how much total dark matter mass exists, we can’t decode much about what individual chunks of dark matter might be made of.  I’ve talked before about Massive Compact Halo Objects (MACHOs) and Weakly Interacting Massive Particles (WIMPs), but these are just two possibilities.  Other theorists have talked about Modified Newtonian Gravity (MNG), where gravity may work differently on the grand scale than it does on our small Earth scales.  Or perhaps it’s something I haven’t seen before.  Maybe what we call dark matter is just a large population of ancient black holes....

Dark Matter may be more Massive than it already is!

Dark Matter; Dark Energy; We basically use the term ‘dark’ as a cool sounding version of ‘We have no clue what this is.’ But Dark Matter is a better name than ‘We haven’t a clue’ Matter. Over the years, Astronomers have been trying to pinpoint what the stuff actually is that seems to permeate the universe and makes up 26.8% of the entire total energy-mass (Compare this to a paltry 4.9% of ordinary matter, ie the stuff we can see). But now, as per usual, theorists have come up with another possibility for the source of dark matter: moderately sized,...
