An event that lies outside of one of these constructs is spacelike relative to the event that defines it. For 10 points each:
[10m] Name these constructs that are formed by the 45-degree lines emanating from an event on diagrams whose temporal axis is scaled by c.
ANSWER: light cones [accept null cones; prompt on cones]
[10e] Light cones help visualize causal relationships in this theory. A foundational postulate of this theory says that the laws of physics are the same in all inertial reference frames.
ANSWER: special relativity [or special theory of relativity; or SR; prompt on relativity]
[10h] One of these statements specifies that the spectrum of the four-momentum must lie within the closed future light cone. The Haag–Kastler framework and these statements both express the properties required to construct mathematically sound relativistic quantum field theories.
ANSWER: Wightman (“WHITE-mun”) axioms [or Gårding–Wightman axioms]
