1 million stars per cubic light-year!

[Yousuf Khan]

In these early galaxies, called Ultra-Compact Dwarf galaxies, they think
there is a density of 1 million stars per cubic light-year! I don't
think it even gets that dense inside our galactic bulge. Can you imagine
a supernova going off inside that mess? I'm imagining a bunch of skunks
in a cage spraying each other. :)

Another interesting thing about these galaxies, it doesn't look like
Dark Matter can explain or even affect these things -- they are too
dense. The only explanation for them is normal matter. Again seems like
non-Dark Matter solutions have it right. You don't even need MOND here,
just simple Newtonian Dynamics works here, though MOND would work too,
but Dark Matter wouldn't.

"Up to now, exotic dark matter has been suggested to explain this
'missing mass', but this is not thought to gather in sufficient
quantities within a UCD. In their paper Mr Dabringhausen, Professor
Kroupa and their colleague Dr Holger Baumgardt present a different
explanation. "
