I The problem with measuring short distances

  1. Apr 11, 2017 #1
    When we try to measure shorter and shorter distances. eventually we have to put in so much energy into such a small space that it creates a black holes, thus makes it impossible see inside. So there is a limitation to how small distances we can measure.

    Exacly how does this happen? Why do we need so much energy to measure a very short distance? How is the black hole created?

    Can you give a reference for where you learned this?

    If you fast forward to 21m and 15 seconds in the following video, the speaker describes why there is a limit on how massive a elementary particle can be before it turns into a black hole.



    (I realized after I posted this that it may not be what the original poster was referring to)

    I'm sorry. I don't remember the references. I'm not sure what to search for either.

    He doesn't say why; he just asserts it. To the best of my knowledge, it's not a proven theorem; it's just a plausible speculation in quantum gravity that most particle physicists think will be confirmed when we actually have a theory of quantum gravity.
