Why should dark matter be so exotic as to not be all around us?

But it is all around us; we've known that for some time. We're just not detecting it. It could be that the density at the galactic center is just that much higher, or it could be that just the density of the dark matter antiparticles is much higher there.

Minor quibble -- but how can you "know" about something you've not detected? You can theorize about it, sure -- but that's not "knowing."

Thanks for responding.

'Still a little tough to grasp undetectable matter that should be coupling to gravity, locally.

Best to You.

Your statements, taken as a pair are contradictory; what I think we are supposed to think is that the math demands that there be a mass large enough to explain the part we do see and dark matter is what we currently call it.

And, if it exists, it can't all be balled up in one little corner to fit the current notions.

Wasn't it Faraday who said that space had to be either completely empty or completly full?

Sorry, I couldn't resist.

When it's in you, you can speak in tongues. ;-)
