Our universe has properties that are determined by thevalues of the fundamental physical constants, and it would be a muchdifferent place if the charge of the electron, the mass of the proton, orthe speed of light was substantially different from its actual value. Forinstance, the speed of light is so great that the effects of relativity usuallygo unnoticed in everyday events. Let’s imagine an alternate universewhere the speed of light is 1,000,000 times less than it is in ouruniverse to see what would happen. An airplane has a length of 60 m when measured at rest. When the airplane is moving at 180 m>s (400 mph) in the alternate universe, how long would the plane appear to be to a stationary observer? (a) 24 m; (b) 36 m; (c) 48 m; (d) 60 m; (e) 75 m.
