Planck scale (uncountable)
(physics) The scale at which quantum-mechanical effects become significant to depicting spacetime & other gravitational phenomena, typically defined as being on the order of one Planck length (~10 m).
If physical reality is totally finite, then the Copenhagen interpretation might be an approximation to an information processing system below the Planck scale. Source: Internet
The novel particles predicted by GUT models are expected to have masses around the GUT scale —just a few orders of magnitude below the Planck scale —and so will be well beyond the reach of any foreseen particle collider experiments. Source: Internet
Loop quantum gravity makes precise predictions about the geometry of spacetime at the Planck scale. Source: Internet
However, Van den Broeck concludes that the energy densities required are still unachievable, as are the small size (a few orders of magnitude above the Planck scale ) of the spacetime structures needed. Source: Internet
If Lorentz symmetry can cease to be a fundamental symmetry at Planck scale or at some other fundamental scale, it is conceivable that particles with a critical speed different from the speed of light be the ultimate constituents of matter. Source: Internet
It follows, then, that spacetime has an elementary quantum granular structure at the Planck scale, which cuts off the ultraviolet infinities of quantum field theory. Source: Internet
