lukemcleod Posted June 14, 2013 Share Posted June 14, 2013 (edited) Ok so I'm not a scientist but understand most things like einstine's theory that says travel at the speed of light away from earth and back again and u will arrive in the future so I have a hypothetical question about this. It goes like this if we had a calculation to work out how many light years you would need to travel to how far in the future u go ie. 2 light years away from and back would equal 20 earth years, and if we sent a huge light emmitting miirror in to space and faced it toward earth and used a light emmitting telloscope to focus on the mirror with that mirror being 2 light years from earth if we looked through the telescope would we not see earth 20 years into the future as that would be the time it would take for the light being emmited to travel from the tellescope to the mirror and back to earth Edited June 14, 2013 by lukemcleod Link to comment Share on other sites More sharing options...
