Large Scale <-> Small Scale failure of intuition.

  1. Dec 24, 2012 #1
    If at very large scales of matter our intuitive logic fails to explain it (Black Holes) and at very small scales of matter untuition again fails (Quantum effects) then is there a connection between those two groups of phenomena?

    part of superstring theory talks about r and 1/r dimensions ie as one dimension gets larger the other gets smaller as in r and 1/r . So one would double in size and the other would 1/2 in size.

    see the extra dimensions section of the wiki article

    Part of the problem of explaining what goes on inside black holes is the fact that quantum theory and general relativity must be used together and they don't mesh.

    Now I wonder that since black holes create quantum considerations, why don't a small number of particles that just happen to be very condensed create general relativity sensitivities?

    To answer this, you'll have to study QM, GR... in depth and then begin to formulate a theory that can answer your question and still stay consistent with existing theories and experiments.

    In theory there are such things (mini black holes), but they have never been detected. Also, they would evaporate rapidly (depending on the mass).

    The only connection is that your intuition is built on experiences with objects of a certain range of sizes traveling with a certain range of velocities. The farther you get from this, the worse your intuition gets.

    Aha! Mini blackholes might be the answer of a connection between Quantum Mechanics and General Relativity.

    Black holes of any size present a problem between quantum theory and general relativity because of the singularity at their center, though mini black holes are considerably more 'quantum' affected.
