p1..p2..p3..p4...atomic clock 1 >>> 20 km/s

p1.....p2.....p3.......p4 atomic clock 2 >>> 45 km/s

electron iside AC1 is making small ellipse

electron iside AC2 is making more big ellipse

20 km/s and 45 km/s respect to point p1 ...

everything is moving = each body was in past in some point

electron speed is constant problem is that coordination system
motion make biger or smaller distance durig electron is trying
close circle around center
