Dark Matters
This Science News article on dark matter intrigues me. If dark matter is just an undiscovered "heavy sub-atomic particle how can it have the weird properties postulated by these observations? If on one hand DM is responsible for seeding standard matter galaxies by gravitational attraction, then what happens with DM and gravity when GM is NOT found in the galactic center but outside (in conflict with Newtonian and Einsteinian gravity) in the galactic halo? Anybody 'splain to me what's possibly going on?
