Consideration of the problem of ambiguous meaning of the word ‘reality’. Clarifying what is being modeled by currently mainstream physics and highlighting what is missing. The way in which sensory awareness is driven by receipt of sensory stimuli is discussed. As well as showing that sensory stimuli exist in the environment, and can be detected (as objective evidence). A reason for the constant speed of ‘light‘ in a vacuum is given. It is proposed that disturbance of the medium filling ‘empty’ space can account for magnetism, effects of electric fields, electrostatic forces, electromagnetism and effect of gravity on matter. Discussion relevant to General Relativity follow. Observer independent passage of time and non simultaneity are considered. Problems in Quantum physics are identified; the relativity (‘seen this way’) nature of measurement, measurement changing the condition of the measured, missing object permanence, vulnerability to illusion, the model of ‘light’ currently used functions to account for result but is probably not correct i.e. does not correspond to observer independent reality The alternative, singular divisible environmental wave and ‘solid-like’ particle, is given as an explanation of curious quantum behaviour. Finally hydrodynamic analogs are mentioned.
