A gauge named for these constructs makes the gluon fields in QCD transverse and can decouple Faddeev (“fuh-DAY-yeff”)–Popov ghosts. Two of these constructs cannot be made parallel to each other by tilting if the Weyl (“vile”) tensor is non-zero. Gravitational lensing creates caustic surfaces by causing these constructs to fold in on themselves. Kruskal–Szekeres (-5[2])(“SECK-uh-resh”) coordinates (-5[1])are used instead of Minkowski coordinates since they prevent distortion of these constructs. (-5[1])The orientation (10[1])of the top of these figures changes when they “tip” near black holes, (10[2])which can lead to closed (-5[2])timelike curves. Events outside of these figures (10[2])are not (10[1])causally (10[4])linked. (10[1]-5[2])These figures (10[1])are formed by 45 degree lines (10[1])coming from a single point on a Minkowski diagram. For 10 points, what shapes are used in relativity to visualize the possible paths light can take from a point in spacetime? (10[1])■END■ (10[6]0[1])
