Packet M: Bonus 10
Relativists and quantum field theorists typically disagree on whether a quantity denoted by this letter should have a “minus, plus, plus, plus” or “plus, minus, minus, minus” signature. For 10 points each:
[10e] What letter’s lowercase form denotes the metric tensor? The capital form of this letter represents the constant in a “universal” inverse-square law theorized by Isaac Newton.
ANSWER: g [accept big G or little g]
[10m] The metric around a spherically symmetric object or a point mass is named after this scientist. Two times big G times mass over the speed of light squared equals this scientist’s “radius.”
ANSWER: Karl Schwarzschild [accept Schwarzschild metric or Schwarzschild radius]
[10h] The metric tensor and its derivatives determine the shape of these constructs in the central equation of motion in general relativity. In GR, all free-falling particles follow these constructs.
ANSWER: geodesics [prompt on straight lines]
