Packet 2: Bonus 9
This theory addresses a thought experiment in which two observers both see a lighting strike, one on the train and the other standing beside the tracks. For 10 points each:
[10e] One of the 1905 annus mirabilis papers presents what theory that postulates the speed of light in a vacuum is constant?
ANSWER: special relativity [or SR or the special theory of relativity; prompt on relativity]
[10m] In special relativity, events that are simultaneous with an observer’s present occupy a hyperplane that is hyperbolic-orthogonal to this construct. This is the path that the observer takes through spacetime.
ANSWER: the observer’s worldline
[10h] Since events in this region of spacetime are causally disconnected from an observer’s present, they can appear simultaneous with it in other reference frames. This term refers to the area outside the observer’s light cone.
ANSWER: absolute elsewhere
