Say, if I traveled to Pluto and back at the speed of light, and it took 'x' amount of days, how would that be relative to the amount of 'time' it took to come back for someone here on earth who was keeping track?
....in the simplest words possible of course.  |
Pluto is 30.993 AU from earth today
1 AU = 149,597,870.691 km
speed of light = 299,792,458 m/s
by my math, I think it takes light 4.3 hours to travel from Earth to Pluto (at other times it is 5.5 hours).
x = 0.36 days (round trip)
