according to an observer alice in a certain inertial reference frame, a pair of spacetime events 1 and 2 occur at a separation distance of 100,000 km and with a time interval 1 s between them. if bob is moving in an inertial frame in which the same two spacetime events appear to occur at a separation distance of only 1 km, then, according to bob, how much time appears to elapse between the two events? hint: it may be helpful to recall the lorentz-invariant spacetime interval.
