What kind of line represents “a moment of time” on a spacetime
diagram?
QUESTION 8 What kind of line represents "a moment of time" on a spacetime diagram? (You must answer in one or two sentences!) Parabola, because it look like a bowl. "Now" doesn't exist for all observers so there is line that represents a moment in time! Lines that are parallel to the spatial/"x" axis. Lines that are parallel to the temporal/"ct" axis.
