comment Can electrons within a positive ion absorb and reflect light?
It will be complicated, because it is a lattice of some type, as with all solids. One will have a mix, but not at the same delta(t) on the same atom, except if it is the whole lattice interacting. The probability for the last is small in not metalic and non crystalline objects.

Physics is about observations . theories fit observations. where they stop fitting them, they are changed or replaced. gravitational thepories describe observational data. The name "gravity" was given to falling things, as I said above. It is a name to encompass observations, like "wet" , "hot" etc. The theory about the observations of gravity, falling apples etc, came after the fact, Newtonian, and had to be modified with General Relativity when discrepancies were found to exist.

The hand is a complicated system. The light has zillions of photons, with many frequencies, all these above happen at the same time with some percentage, even though they are independent of each other

comment Are there any open questions in physics that a layman can analyze?
There are a number of experimental contributions that can be made, not theorectical. There is crowd sourcing of observations in astronomy americanscientist.org/science/pub/… , and also an attempt was made with crowdsourcing for data from the ATLAS experiment at LHC daily.zooniverse.org/2014/11/26/higgs-hunters-is-here . One could search for similar projects.

Gravity is an observational phenomenon described by a theory with the same name. Gravity is : an apple falls to the ground. The moon turns around the earth etc. Gravitational theory describes gravitational observations. The reality exists and the theory models it.

the vibrations/heat transition is also a quantized business at the level of molecular lattices, excitations and transitions among atoms/molecules

Thus sun light falls on your hand. Part of it is absorbed, heating your hand, i.e the photon energy went to the lattice as vibrations/heat, part of it is reflected, i.e. elastically scattered from the fringe field of the outer atoms, and part of it may excite a surface atom's electron to a higher level ( having the correct energy) and then the electron can drop back and release a same frequency photon in a random direction, or cascade down emitting two or maybe more photons of lower frequency. The total generates in your eye the color of your hand.

try the science fiction and fantasy site , where one can believe in anything scifi.stackexchange.com . This site is not about beliefs, but about mainstream physics: observations and mathematical models that fit the observations and predict new ones.

comment Can electrons within a positive ion absorb and reflect light?
It is a general observation. It is due to the fact that in reflections the frequency of the light does not change. This means the photons undergo elastic scattering of some type. True for all materials. If the reflected color changes, then it is a different story. It might be a molecular excitations or atomic electron excitations. In metals the lattice has the conduction band in the field of which the photons undergo scattering. In ordered crystals and glasses the whole lattice field interacts with the photon allowing with elastic scattering the transparency.

comment Fractionally charged Quarks
@garyp If you consider a plethora of experimental values from a plethora of experiments you must have a very strange idea about experimental evidence. The evidence is in the symmetries seen experimentally that are explained by the specific quark model SU(3)xSU(2)xU(1), and not another. Similar to crystal symmetries , that define the crystal.

The plot above, and the ones in the link, are the results of a great number of experiments in the 1950's and 1960's. Did you read the link?

comment Understanding the basic concepts of quantum mechanics using a model
@RobotMan I am not into a computational lingo, i am a simple experimental physicist. The simple fact about the cards being in a fixed state can be ascertained by a kibitzer, i.e. a third party to the game who does not disclose knowledge.
