Main Question or Discussion Point
the title pretty much says it all. i am just wondering if dark matter (which doesn't interact with light i believe) gets eaten by black holes, or is unaffected by them.
no.hold up, what do you mean by dark energy acts like negative gravity? like dark energy is repelled by large masses?
I'm not so sure about that. The thing about DM is that it (if it exists) is thought to be essentially collisionless, so that not only would you not notice if DM passed through you (which it presumably does all the time) but that two lumps of DM would notice passing through each other. This is in contrast to normal matter which obviously collides with itself at the molecular level.I view it highly likely that galactic core SMB's originated almost entirely from dark matter.
It would be wrong, for example, if DE is nothing more than the cosmological constant ([itex]\omega[/itex] = -1).According to current understanding the ratio of dark to ordinary matter is the same for the entire history of the universe, back until the very first moments where we really don't have a clue anyway. Of course we really have no clue what DM is anyway so that could be wrong.
Point taken! The general thread was discussing DM and DE, and as you said, I got confused as to which one we were talking about here.You're confusing your darks Garth! We were discussing dark vs baryonic matter not dark energy. Dark and baryonic matter densities both drop with the inverse of the volume of the universe, hence their ratio's remain the same.
