There is no way to measure or register any time unit that is shorter than the time it takes a photon to cross an electron. This is the inescapable conclusion arrived at from the way distance and time are defined in my proposed physics. Anything happening faster than this minimum time is perceived by us as instantaneous.
A consequence of this is that any measurement involving distance or time involves an uncertainty. We cannot know exactly where something happens, nor can we be 100% precise about when it happened. There is a tiny time-interval and distance that cannot in any way be pinned down precisely. This is not due to a lack of technology or our own interference in the measuring process, but an inescapable consequence of the fact that time and distance are tied up directly to the dimension of the electron.
This conclusion is similar to the one arrived at in conventional quantum physics. Fiddling around with equations related to Planck’s constant and units, Heisenberg found that the universe is fundamentally uncertain. For example, we cannot be precise about both the momentum and the position of a particle.
Having arrived at this conclusion through pure mathematics, with no comprehensive model of what all the various variables and constants relate to in the real world, there was initially a great deal of confusion related to what Heisenberg’s discovery meant. Many ascribed it wrongly to technology or the effect observers have on measurements. It took some time before the uncertainty principle was generally understood to be a fundamental aspect of the universe. However, we have yet to hear a more specific explanation from the halls of conventional quantum physics. It will be interesting to see if they too eventually arrive at the conclusion that the uncertainty of the universe is directly tied up to the dimensions of the electron and the time it takes a photon to cross it.
