Physics Questions with a nod towards the Philosophical

  1. Is the nature of space within an atom different? I calculate the energy density from the electric field in the space between a proton and its ground state electron to be ~ 1011 J/m3. Vacuum energy is around 10-13 J/m3. That’s 24 orders of magnitude between two regions of ‘empty’ space; seems like something might be going on.

  2. Do matter/probability waves have all wave characteristics? Do they have phase/group velocity? Are they subject to Doppler shifting? Do they have nodes/antinodes?

  3. Is space granular? Is it quantized as charge and energy are? Is time quantized? Energy is. Charge is. Matter is. So is spin and angular momentum; why not time? Perhaps the fundamental unit of time would be the Planck time, 10-43 seconds. Maybe physics breaks down at the Planck time because there is no shorter interval. If true, quantized time would have profound implications for existence. If time is granular then existence would be also. We would be living life as if it were a flip book, with the pages flipping so fast that we couldn’t detect it, but nonetheless experiencing intervals of non-existence.

  4. Did primordial non-linear dynamics account for the slight inhomogeneities in the distrbution of mass and energy in the Universe?

  5. What is the measure of randomness? Is any system truly random or just at a level of complexity that makes it appear random?

  6. Is complexity conserved? Think of the Standard Model with its overrich garden of subatomic particles: fermions, bosons, hadrons, baryons, leptons, mesons, and so-ons; the Eightfold Way, QED, QCD. Yet baryonic matter is only 20% as plentiful as dark matter. If complexity is conserved, then dark matter should be 5 times as complicated as that described by the Standard Model. Searching for a single or even a small cadre of WIMPs may be a gross simplification.
