Determine the time [in day as measured by a clock at rest (on the rocket) taken by a rocket to reach a distant star and return to earth with a constant velocity  if the distance to the star is 4 light years (A light year is defined as the distance travelled by a light beam in vacuum in one year).
    Correct answer is '29.2'. Can you explain this answer?

    From the Lorentz transformation equation for time, we have

    Here x = 2 x 4 light year
    = 2 x 4 x 365 x 24 x 60 x 60 x c cm.
    = 2.523 x 106 c,
    where t is the time taken by the rocket to reach the star and back to the earth as measured by an observer in a stationary frame at earth and t' is the time measured by the clock in the moving rocket for the total journey
    Now,  where 
    ∴ 
    or  ...(ii)
    Substituting the values of x and v in equation (2), we get


    or 
    = 2.523 x 106 sec
