The other term you might have heard is 'Dark Matter', which again is a name for something scientists have no idea what it is. The problem is the mass of all the stars and planets in any galaxy is no where near enough to account for the gravitational effects of said galaxy i.e. the speed it rotates, gravitational effect on other galaxies. When I say there is not enough accountable mass, I mean scientist cant account for 95% of all the mass. Scary stuff.
Any way , back to topic. What does the Xlive gold package cost?
Apparently on the PS3 all access is free, you only pay for down loads.
Voice chat, video chat, multi-player gaming - all free. That should stir things up a bit.
