How come we say space and time when it should be space=time. You can eliminate measuring distances and measure them in time. Two objects can always be measured apart by time as long as there is a universal speed (light). I am 0.000008sec (at light speed) from my mailbox for example. The universe expanding could be time. There is no distance at all. Like the big bang all matter is one thing only seperated by time. The closer to people come together the closer in time they are. Have I gone to far with relative time?
