as you aproach the speed of light time slows down.we all know how long 1 earth year is. assuming you are travelling at the speed of light you wood have to calculate an earth year in space to return to earth 1 year later.when you return to earth how long were you away (in earth years)

The phenomenon you are describing is called time dilation. As you say, as you approach the speed of light time for you slows down. So for you, time appears to run at the same rate it always has - you can use a clock to measure your year out. Unfortunately, your question contains a flaw. Relativity forbids matter travelling at the speed of light. Mathematically, time for you would stop. Which means as soon as you hit light speed, the rest of the Universe would have run on to extinction at inifinite speed. There would be no Earth to return to.

according to einstein's theory ,If u can travel in the speed of light, time is compressed and becomes less than the earth.....assume tat u went 2 space at 2006 in the speed of light.After 1 year u were returning back.... at tat time in the earth,year is 2007 but if u placed a clock in ur shuttle definitely it will show 2006....

1/3 of a parsec.

One year, although you will have only aged nominally (it would feel like an instant to you).
