Our lives consist of atoms and molecules within spacetime, interacting with others based on distance, charge, gravity, energy state, relative motion, and so forth. As we, our instruments, and everything within spacetime interacts similarly, it is quite natural for us to consider our observations to represent reality. Yet careful observation and investigation reveals anomalies.
When confronted with such problems, we are normally best served by postulating a new factor, such as in geology, where extra floods were added to Noah’s which could accommodate the fossil record. In astronomy, new epicycles were added to account for observed celestial motions. In cosmology today, new dimensions are added to account for observations of matter and spacetime.
Like now, when revolutionary advance is necessary, it has been accomplished by changing the focus of research efforts from adding new factors to imagining the simplest unifying explanation for our observations. This change gave rise to theories of heliocentrism, quantum mechanics, evolution, blood circulation, plate tectonics, relativity, and many others.
Physical models now assume dimensions in which atoms, charge, forces, and mass appear are real, and we postulate new dimensions to accommodate observations in physics and astronomy. These are poor approaches because they are founded on acceptance that time and space perceptions are essentially real, rather than the more conservative and skeptical view that they are merely observations. Thus, our investigations should focus on processes giving rise to perceptions of spacetime dimensions, matter, charge, and energy.
This is the only approach with which we may enjoy historically justified confidence in our ability to progress adequately.
