Do you ever think about "doubly special relativity" and get upset

This is pretty obscure

The idea is: The planck length is supposed to be an inviolate limit, but if Lorentz contraction occurs (IE length contraction when something is moving at relativistic speeds), then the effective planck length changes. Observers in different inertial reference frames will measure a different planck length for the same object.

@mcc This seems like a problem stemming from the incompatibility of general relativity and quantum mechanics, and which I imagine would neatly drop out of a consistent theory of quantum gravity. So it makes sense most physicists (working well away from one or both limits) don’t need to worry, and those who do are actively working on a theory of quantum gravity (and so would need to demonstrably overcome this issue to be taken seriously)
