Physics at a Crossroads: Weird Concepts or Orthogonal Projections

Today’s physics describes nature in “subjective concepts” (concepts of observers), such as spatial, temporal, wave, particle, force, field. There are coordinate-free formulations of special relativity (SR) and general relativity (GR), but there is no absolute time in SR/GR. Thus, there is no “holistic view” (view from all possible perspectives at the same instant in time). I show: Euclidean relativity (ER) provides a holistic view by describing nature in “objective concepts” (concepts that are immanent in all objects). “Pure distance” replaces spatial and temporal distance. “Pure energy” replaces wave and particle. I give one example where “process” replaces force and field. Each object’s proper space d1, d2, d3 and its proper time τ span a Euclidean 4D spacetime (ES), where d1, d2, d3 and d4 = cτ are pure distances. The new invariant is absolute, cosmic time θ. All energy moves through ES at the speed c. An observer’s reality is created by orthogonally projecting ES to his proper space and to his proper time. The two projections are reassembled in SR/GR to form a non-Euclidean spacetime. Information is lost in all projections. Thus, there will always be unsolved mysteries if we ignore ES. Physics now has two options: (1) It rejects ER and continues with weird concepts (cosmic inflation, expanding space, dark energy, non-locality). (2) It accepts ER and solves 15 fundamental mysteries (including time’s arrow and the Hubble constant tension) without these weird concepts. All solutions are purely geometrical. In particular, they require neither forces nor fields.
