B GR Worldlines of a particle

  1. Mar 11, 2017 #1
    In GR. What's the worldline of a quantum particle before and after it undergoes state reduction (before and after Born rule applied)?

    GR is a classical theory. I'm not sure there's a good answer to your question, and I'm rather doubtful that a quantum particle can be represented as having a worldline at all. Consider the double-slit experiment, for example. A worldline would go through only one slit, the quantum particle goes through both.

    Pervect is correct, GR is a classical theory, not a quantum theory, and quantum particles do not have worldlines. That means the OP question is not well posed and cannot be answered.
