Magic already fills all the spaces that physics cannot reach.
Take spacetime (you can just as well call it the mellifluous aether which carries gravitational waves from the sun to the distant reaches of the solar system where other beers cannot reach).
The stretched rubber-sheet analogy to explain spacetime and gravity is just that – an analogy. And not a very good one as xkcd has so well illustrated.
spacetime magic — by xkcd
“Spacetime” is a label for any mathematical model which combines space and time into a continuum. It is just a model. But why that model should apply is magic.
Spacetime is just an imagined structure of the universe and is imbued with mathematically-defined properties such that “spacetime is distorted by the mass of bodies which exist within it and these distortions, in turn, affect the motion of those masses”. A somewhat circular argument which does not explain the “why” or the “how” beyond “it must be so, because it is so”.
Spacetime does not explain the existence of gravity. It merely shifts the need for magic to explain magical attraction (labelled gravity) to another place where physics cannot reach. In a universe where motion is not independent of time, and where the very duration of time can vary as a consequence of motion, even the magnitude of the 3 physical dimensions become variables subject to the observer and his motion. Not to mention that mass can be energy and some of both can be dark. Neither mass nor energy nor momentum can any longer be conserved, because phantom dark energy can be called upon and injected into the equations whenever it is needed to explain the unexplainable. And to have a “phantom” class of undetectable, unobservable dark energy which is doubly undetectable, does seem to go over the top. Rather than just put dark energy and dark matter, and even phantom dark energy into the category of magic, intrepid physicists have invented new classes of unknown, unobservable, undetectable, sub-atomic particles. Some have charm and some have spin. Some have properties which are as yet undefined but will be sufficient to the explanation required to be constructed. Why not just call them “magic particles”?
Physics no longer goes for the parsimonious explanation. Big Physics seems nowadays to be based on introducing complexities wherever possible rather than looking for the least complicated explanation which is sufficient to the explanation. For every ultimate, fundamental particle that is “found”, but found wanting, two further magic particles have to be invoked.
Of course, there is a Grand Unified Theory which explains electromagnetic, weak, and strong interactions and naturally there is a Theory of Everything which even explains gravity. It is quite simple and sufficient to the purpose. It is called Magic and it occupies all the spaces that Physics cannot reach.
It is time for a Heineken. Now if I could only remember the right spell and the right incantation to go with it, ………
