A recent article in the European Physical Journal explains how the behavior of a complex dynamical system could be explained by the superposition of simpler underlying systems. The work hypothesizes that special relativity and quantum-mechanical dynamics are mathematically identical to two interlocked processes operating at different energy levels.
Grand unification theories have been directionless for decades, attempting the impossible – some spawning particles and others energy fields, to plug the holes in improbable theories. They have been inventing strings, membranes and other such constructs, that would make a dress-maker blush but with little advancement in fundamental knowledge. The notion that complexity can be explained by superposition of simpler processes have been with us for decades as well, but that sounded too simplistic for the pretending geniuses behind ivy walls.
Simpler explanations to complex phenomena will always dominate even though it may not be sufficiently robust to prop up the ego of Nobel seekers.
