Only in Natural Concepts Does Nature Disclose Her Secrets

Today’s physics describes nature in “empirical concepts” (based on observation), such as coordinate space/time in special relativity (SR), curved spacetime in general relativity (GR), and wave/particle. There are coordinate-free formulations of SR/GR, but there is no absolute time in SR/GR and thus no “holistic view” (universal for all objects at the same instant in time). I show: Euclidean relativity (ER) provides a holistic view by describing nature in “natural concepts” (immanent in all objects). Proper space/time (pure distance) replace coordinate space/time. Curved worldlines in flat Euclidean spacetime (ES) replace curved spacetime. “Wavematters” (pure energy) replace wave/particle. Any object’s proper space d1, d2, d3 and its proper time τ span d1, d2, d3, d4 (ES), where d4 = cτ. The invariant is absolute, cosmic time θ. All energy moves through ES at the speed c. An observer’s view is created by orthogonally projecting ES to his proper space and to his proper time. For each object, there is a 4D vector “flow of proper time” τ. Information is lost if the 4D vector τ is ignored, as in SR/GR. ER solves the Hubble tension. Also, ER declares dark energy and non-locality obsolete. I conclude: (1) Acceleration rotates an object’s τ and curves its worldline in flat ES. (2) Information hidden in τ solves 15 mysteries. (3) Different concepts disable a unification of SR/GR and ER. Either scope is limited. We must not apply SR/GR but ER whenever τ is crucial (high-redshift supernovae, entanglement). We must not apply ER but SR/GR whenever we use empirical concepts.
