earth....it will reach earth in 2-years....a person with a telescope on earth

would have aged 2-years during the length of it's journey from the star to

the reflector on his telescope....and (if it was possible) a spaceship with

an astronaut onboard is traveling at the speed of light, and following the

photon to earth....he would travel (11,749,178,300,000 miles), or 1.1749 x

10^13 miles and age 2-years....there is no time-dilation when traveling

through "space". The photon aged 2-years, the astronomer aged 2-years, and

the astronaut aged 2-years....light-speed (C) is a constant, and it's effect

in "space" is constant.
