comment What do the wave functions associated to the Fock states of each mode of a bound state system mean?
think you are on to something here & that the strong analogies with classical physics are not mere coincidence, and have pursued similar ideas over many yrs... but all due respect/ sympathy, strictly speaking isnt this all arguably sketching out a "hidden/ (local?) variable theory"? my intuition, while weak on math details, maybe one way of sorting this out is to try to understand what simultaneous detections of particles mean, or are possible to measure... anyway would like to strongly encourage further/ ongoing discussion on this topic (a zen koan?) but in some less-restrictive venue...

comment Basic Quantum Entanglement
it was wheeler who talks of the "great smoky dragon" and how old photons from distant stars are entangled.

comment Can a photon be captured in a grid space representation at a fractional Planck position?
ok! the establishment hath spoken! except... wheelers it from bit has shades of digital physics. 't hooft nobel prize physicist proposes cellular automata models last few years. etc! are these two (and many others) "nobodies of any importance"? oh yeah, and theres also bohm =O

comment Can a photon be captured in a grid space representation at a fractional Planck position?
it is conjectured both that there is no detectable 3d grid, and that there is (contrarian/ minority/ near radical pov), and there are some recent serious cutting edge experiments to try to discriminate the two cases using very sensitive detection. the latter case has been called "evidence for living in a simulation"... see eg simulation for misc refs

comment Why are so many relationships in physics described by equations?
unreasonable effectiveness of math in physical sciences, wigner / wikipedia. on the contrary side, significant areas of physics are known to be undecidable & new areas are found all the time.

comment In the oil droplet experiments that suggest de Broglie’s pilot wave theory might be accurate, what does the fluid surface correspond to?
the "too many dimensions" objection can be found throughout QM history as an objection to local hidden variables (eg Bohmian mechanics), but there are very many classical systems that have many "dimensions of freedom" that do not correspond easily to physical dimensions. eg, "dimensions" in robotics. in other words complicated mappings between 4d time/space and existing classical systems already exist. agreed it is a key difficulty for any local hidden variable theory to confront/ "disentangle" because of the complexity of the mappings. but perceptual complexity does not rule out existence.

comment In the oil droplet experiments that suggest de Broglie’s pilot wave theory might be accurate, what does the fluid surface correspond to?
re, possibility to advance under research, maybe to an atomic model: agreed the oil drop apparatus is limited but think there is a possibility for 3d simulations with more complexity. think this is not understood yet but that they are basically modelling soliton dynamics. and then one can look into eg linking it up with already existing knowledge in the area (but admittedly currently obscure) such as soliton model of the atom / Rybakov, Saha

wrt the analogy the "fluid surface" corresponds in 3d to space itself. it may sound strange but space is already recognized to have a concept of "density" wrt GR "stretching" eg around gravitational fields. this is new/ active research and is continuing to be researched/ extended by Bush and others and think it will play out over a long period and have widereaching ramifications.

comment The universe is said to have begun as a singularity, but how do we know nothing else existed?
there is a steady state model of the universe that has a few proponents/ evidence.... its somewhat similar to the big bang except the idea that matter is continually streaming away from the big bang toward a "drain"

comment In the oil droplet experiments that suggest de Broglie’s pilot wave theory might be accurate, what does the fluid surface correspond to?
agreed it is in very preliminary stages but the proponents of this research "paradigm" eg Bush & others think it is more meaningful than a mere curiosity and can be further extended, ie it can be seen as an ongoing research program, and understood this conflicts to various degrees with "conventional wisdom". its also quite remarkable because its a purely classical analog that the founders of QM were wholly unaware of around a century ago at the inception of the theory and "interpretations." it also ties in with new developments in QM measurement eg "reality of wavefunction" etc

comment Double slit experiment and pilot waves
QM is now over a century old. there is a vaguely similar concept in software dev called "lock in" that also explains inertia and resistance in consideration of "alternative theories". more on the wave experiments here, superclassical/ emergent QM, recent developments, rough outline/ overview/ leads

comment In interpretations of QM where the wave function is real, what does that mean?
try looking into the work by Cavalcanti et al, sec [o] on this page ("superclassical/ emergent QM"), also another Physics question refd there

comment Is gravity just electromagnetic attraction?
the cited blog page seems mostly speculative & has no specific citations other than general/ vague ones. however, this rough idea is at the heart of "grand unification theories". see also classical unified field theories and alternatives to general relativity / wikipedia. another angle studied mainly wrt black holes: gravitational soliton

comment What evidence is there of a universe older than 13.8 billion years
think this is a halfway decent question & not really a so-called se "list question" (whatever that is). there is some misunderstanding here. the current interpretation of the new found massive black hole is that the current model of black hole formation is up for question/ reevaluation, not the current estimated age of the universe. so far havent heard any mainstream physicists asserting the age of the universe has to be reevaluated although that is one alternative....
