Around in unforeseen circles

  1. Sep 16, 2007 #1
    Is it possible that we have been (as the planet Earth) within the exact same space as we once had been? Meaning that, within all of our orbits around the sun, all of our trips around the galaxy, all of what we don't know about our relationships with other galaxies, and all of the countless possibilities in our position in space, is it possible we've circled around the loop, crossed and been in our previous position from the same or different angle?

    There is no reality to the notion of a "position in space".

    In order to assert that two events in space-time have the same "position in space", you have to invoke a coordinate chart; and so the notion is completely dependent on how you choose to look at things.
