Suppose you are planning a trip in which a spacecraft is to travel at a constant velocity for exactly six months, as measured by a clock on board the spacecraft, and then return home at the same speed. Upon return, the people on earth will have advanced exactly 76 years into the future. According to special relativity, how fast must you travel? (Give your answer with six significant digits as a multiple of c.)
