Ok so I read this on another site... "the Milky Way is part of the Local Group...The Local Group is calculated to move relative to the CMB at about 600 km/s (2,200,000 km/h)"
When you get into a 'spaceship' and travel say 50% the speed of light, then come back to earth, more time has passed for you than for those on earth.
My question is, does it matter what direction you travel in?
