That charge is the quantum number associated with internal U1 gauge symmetry is something that I can live with. It may be futile to look for some field characterisation or geometric explanation of charge. That physics is only an empirical science can be nuanced somewhat, it leads also to...

An elementary particle has properties like spin and charge. With spin there can still be some kind of notion of rotation, but how can charge be characterized? Does there exists some underlying views or models on charge? Pragmatically, charge can be seen as a strength of coupling with photon...

The article is interesting, but a lot to absorb. Just a few minor points: - You could say a quantum particle has a wave aspect and a particle aspect. In above sentence "particle" has two different meanings. In the article the term "particle" is also used for both. Sometimes for the quantum...

Essentially true; there are however some additional physical processes to take into account. Difference in gravitational potential causes a redshift or with satellites a slight blue-shift. A photon has to perform work to leave a star and looses energy, i.e. redder. The star (and the galaxy it...

There is already a lot of laser guided weaponry. Smart ammunition could be a direction to take. Point the gun or upload the target description; and the bullet, needle or missile will identify or find the target out of itself and follows its trail. It doesn't have to go fast, always. And can...

It seems to me that the root of the problem or issue is that it is tried too much to see quantum particles as semi-classical objects or as particles\waves. The message would then be to abandon those ideas or see those as approximations or illusions. It is more modern to view a quantum particle...

I don't want to wrestle with Latex for complex conjugation of the wave function and replacing time with minus time and such. At some point I may have to. You could also consult the following link especially page 11: https://bingweb.binghamton.edu/~suzuki/QM_Graduate/Time_reversal_I_operator.pdf

Just a thought. Shouldn't you be transforming to the minus of the time parameter? Have you checked the following page, it is to elaborate to repeat here: https://en.wikipedia.org/wiki/T-symmetry

OK, Thanks, I think we can close this discussion. I was hoping to get the reasoning steps in the interpretation of the measured data and its patterns (before it is getting interpreted) explicit to a level that you can start some logical and physical analysis. It might only be in hundreds of...

There is a very crucial point and is exactly what the question is about. There is a large gap between "the measurements" and "show that galaxies are receding faster ..." It was not clear at all that the same galaxy was measured several times and the data compared at these different times. Also...

It's decades ago I studied physics and went into working for software companies. Now I'm retired and have more time to focus on issues in physics, astronomy, quantum mechanics or anything else interesting.

I'm trying to check the reasoning behind the "accelerating expansion of the universe", but do not find anything sufficiently accurate or convincing. For example in "https://en.wikipedia.org/wiki/Accelerating_universe" is put: "Observations show that the expansion of the universe is...
