19M.3.SL.TZ1.a

The diagram shows space and time axes  x and ct for an observer at rest with respect to a galaxy. A spacecraft moving through the galaxy has space and time axes x ′ and ct′.

A rocket is launched towards the right from the spacecraft when it is at the origin of the axes. This is labelled event 1 on the spacetime diagram. Event 2 is an asteroid exploding at  x = 100 ly and ct = 20 ly.

Plot, on the axes, the point corresponding to event 2.
