6. There actually is a gravitational analogue to magnitism...

It's just very, very weak. In fact the magnetic force is very very weak compared to the electric force, the only reason that we notice it, is that because everything is pretty much electrically neutral, due to positive and negative charges more or less canceling out each others electric fields, it's the only thing left.

The effects of the gravitational analogue to magnetism can be seen in reletivistic frame dragging, which was confirmed a little less than a year ago with the gravity probe b experiment.
