    Things become infinite near the Planck scale. Killer?

    BTW notice that their theory is not yet quantized.

    There are a lot of variants of DSR (as you know!) and they
    predict different things, but two features they all have in
    common is they are not quantum theories
    and they happen in flat space.
    The bridge to General Relativity and then on to
    Loop Gravity (quantized version of it) has not been
    constructed yet.

    I think it is about time for DSR to put out a feeler into curved space, and blend into some quantized model.

    I dont know what planck scale singularities could be
    smoothed out during quantization.

    If I had to choose with incomplete information I would
    pick Kowalski-Glikman brand DSR over Magueijo brand. And
    KimKimRimYee brand might not even get carefully considered.
    But I am not making the choices! So I was glad to see their paper.
