hi,guys....i'm new to this particular forum(well,not really NEW...i just haven't posted in quite some time),and i have a question that i really need to have answered.i'm aware that everything in the universe is in motion...i just can't figure out how we know it.if our galaxy is speeding thru space along with every other galaxy,how can we tell that we're moving?how do they know we're traveling at speed x,and in what direction?i don't have a problem believing and accepting these things...i'd just like to know how these things were figured out.
