I Short Distance Quantum Physics

  1. Jan 17, 2017 #1
    Does this paper [https://arxiv.org/pdf/1505.06963.pdf] give sufficient reason to accept/believe that the infinities where we "find" singularities can never really happen because there is a minimum length scale that prevents it? Hoping that I have made at least a reasonable deduction from the article.

    I also sense that they may misuse the notion of quantum fluctuations (based on other threads herein); but reserve the right to be wrong on that too.

    Just interested in getting some opinions on this rather than starting a fight. Sometimes just asking a question in here leads to a scolding.

    Also, what the heck are the prefixes for? I had not seen that before. Hope choosing B was OK.

    For identifying the level of background knowledge assumed in the discussion. "B" is basic (high school), "I" is intermediate (undergraduate), "A" is advanced (graduate). I have changed the level of this thread to "I" (the subject matter could even be "A").

    As I understand it, any introduction of singularities poses problems for QM just as much as GR.
    Possibly a strong theory for Quantum Gravity might one day address these problems.
