Build a ship to travel at near light speeds so that 4 years passes by but you only age 6 months. By what fraction of the speed of light must your ship travel to accomplish this?

0.992156741649c

Explanation:

= Moving observer's period of the clock = 4 years

= Frame of the clock itself = 6 months = 0.5 years

c = Speed of light =

v = Speed of the ship

Time dilation is given by

The speed of the ship should be 0.992156741649c
