## Main Question or Discussion Point

Following the premise of Einstein, man cannot travel at light speed due to the overwhelming increase in mass during the hypothetical attempt. However, a photon has no such limitation... it travels at it's constant. Therefore, if a photon travels from the surface of the earth into space (barring any possible variances from interference of any kind against it's constant), traveling outward for exactly 12 hours, then instantly reversing course and returning to the surface of the earth (24 hours elapsed time measured at the photon), how much measured time will have elapsed on the surface of the earth?
