When I first read "Deep Down Things" by Bruce Schumm. The author didn't say flat out it was not physical. Quoting him: "Without the extension provided by sophisticated scientific apparatus, our senses, our biochemical senses, are just too anemic to invoke or perceive motion in the spaces we have introduced and discussed in this chapter. Might it be possible that the internal spaces of this chapter are in fact no less real than the three-dimensional space of our everyday perception? Could it be that, absent any way to influence or perceive motion in these realms, we simply lack the tools and motivation to evolve the ability to perceive them? I'll leave you to mull this over while moving on to the second and final discussion of this section: that of an important qualification of the nature of the symmetry transformations we've been considering..." Well. After asking physicists later if the gauge symmetry could be physical. They said no. But then is it possible there are physicists who think they are physical? Any paper that describe they could be physical? We don't know the "dna" of physical law as Fra put it. But what if the gauge symmetry was real in the "dna" dynamics of physical law?
