So which version should you choose to explain gravity to your son meanwhile: QM or GR? The new generations of mathematicians have voted with their feet. They ignore both GR and QM and, instead, are working feverishly to integrate features of the two theories into yet another, so-called Theory of Quantum Gravity: “ We want to combine what we have learnt about our world from the two theories and to find a new synthesis.” String Theory (ST) is a promising field that is sucking up resources and tax dollars. It is ‘promising’ because ST will forever remain an IOU. ST has no chance of delivering the goods or graduating in Science. It has no chance because String Theory has absolutely nothing to do with relativity and is conceptually no different than Quantum Mechanics. Specifically, string theorists are busy developing equations to show that space-time is ‘quantized’ (i.e., is made of tiny components). “ The commonsense picture of space and time is rather like that of a canvas on which the activity of the world is painted. Einstein showed that the canvas itself can move about and suffer distortions - spacetime comes alive. Quantum theory predicts that if we could examine the surface of the canvas with a supermicroscope we should observe that it is not smooth, but has a texture or graininess caused by random and unpredictable quantum distortions in the spacetime fabric on an ultramicroscopic scale.”
