The cosmic rays of highest energy are protons that have kinetic energy on the order of 1013 Mev. (a) As measured in the proton's frame, what time interval would a proton of this energy require to travel across a galaxy which has a proper diameter 7.80 × 104 ly? (Assume the kinetic energy of the proton is exactly 1013 Mev.) (b) From the point of view of the proton, how many kilometers across is the galaxy? km
