His horse is named Friday.
you won't get this riddle
He was moving at a reletivistic velocity of 2.71*10^8 m/s with respect to the town so that the lorenz factor, γ, is:
γ = 1/sqrt(1 - v^2/c^2) = 2.33
so the time interval, t, between when he arrived in town and when he left as meassured by the cowboy is:
t = t'/γ
where t' is the time as meassured from the towns frame of reference. t' in this case is 7 so t = 7/2.33 = 3. So the cowboy meassured 3 days that he was in town but he arrived on friday and left 7 days later which is also friday.
that's gooood,
There was a cowboy that went to town on friday and stayed 3 days then left on friday. How was that possible? I will give you a trophy instead of saying you'r right because that will give off the answer.
