    I Physicists disagree wildly on what quantum mechanics says about real…

    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 Direction of time-evolution in time reversed wave functions

    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

    I Direction of time-evolution in time reversed wave functions

    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

    I The quantum wave is not real?

    Well, you can get 10 different answers from 10 different persons. Conceptually you could see the wavefunction as the impact the quantum particle has on its environment, loosely put, or its indirect presence that is felt everywhere. In EM you feel the presence of charge through the em-field...

    I How do you get to the conclusion that there is accelerating expansion?

    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...

    I How do you get to the conclusion that there is accelerating expansion?

    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...

    Always been interested of physics at the edge of knowledge

    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 How do you get to the conclusion that there is accelerating expansion?

    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...
