The Light of Existence
... That it is because it is has never been a very satisfactory answer in science. In quantum realism, the speed of light is the network refresh rate, which is finite because every processor runs at a finite rate, e.g. a 5GHz computer runs at 5,000,000,000 cycles per second. If light goes from one node ...

Short-Lived Lattice Quasiparticles for Strongly Interacting Fluids
... quasiparticles can be made as small as one millionth of their natural value, i.e., ω ' 2(1−10−6 ) [12–14]. In order to appreciate why this is remarkable, let us consider the lattice kinetic update in compact form, Equation (5). The realisability constraint imposes that the discrete populations be no ...
