I am not sure how to impress people with how bad this thinking is. These slice and diced chunks of spacetime, whether voxels, plaquettes and so forth have violations of Lorentz symmetry of spacetime. This means that curiously the symmetry of gravitation would be violated at higher energy, and in fact where it is quantized. These ideas have further been falsified by the lack of dispersion from distant sources. These ideas are bad interpretations of the Planck length. The Planck length is just the smallest length beyond which you can isolate a quantum bit. Remember, it is the length at which the Compton wavelength of a black hole equals its Schwarzschild radius. It is a bit similar to the Nyquist frequency in engineering. In order to measure the frequency of a rotating system you must take pictures that are at least double that frequency. Similarly to measure the frequency of an EM wave you need to have a wave with Fourier modes that are 2 or more times the frequency you want to measure. The black hole is in a sense a fundamental cut-off in the time scale, or in a reciprocal manner the energy, one can sample space to find qubits. The levels of confusion over this are enormous. It does not tell us that spacetime is somehow sliced and diced into briquets or pieces. It does not tell us that quantum energy of some fields can't be far larger than the Planck energy, or equivalently the wavelength much smaller. This would be analogous to a resonance state, and there is no reason there can't be such a thing in quantum gravity. The Planck scale would suggest this sort of state may decay into a sub-Planckian energy. Further, it is plausible that quantum gravity beyond what appears as a linearized weak field approximation similar to the QED of photon bunched pairs may only exist at most an order of magnitude larger than the Planck scale anyway. A holographic screen is then a sort of beam splitter at the quantum-classical divide. LC -- You received this message because you are subscribed to the Google Groups "Everything List" group.
