Oh I know. Im assuming that Dark is wondering if we will ever spiral into the Black Hole at the center of the galaxy. I just used the earth sun system as a smaller scale example. Now thinking back assuming is not the right word there. There fixed. Also what does the schwarzchild radius have to do with us falling into the super massive black hole at the center of our galaxy? All that states is if you crunched a bunch of mass into a ball how small would it have to be for its escape velocity to equal C.
