    Depends. What's in it for me?

    I demand that I may, or may not, be Groonfondle.

    Which brings up the question -- where is it when it is "between" for such a long time? Subspace?

    I need that attachment for my vacuum cleaner. You would not believe some of the things that wind up under my bed.

    I got into an argument with Steinberg once. He won.
    Still:
    "Take the average of the clock-hand positions of the ensemble, and you get a number that can be interpreted as representative of the correct value for a single atom".

    You have to wonder if the interpretation of tunnelling time really corresponds to the time the airline leaves your call on hold.

    This is news to me
    To explain results from the quantum world however, the concept of probability needs to be expanded to include a so-called quasi-probability, which can be negative.

    I found this
    https://en.wikipedia.org/wiki/Quasiprobability_distribution

    Apparently Wigner came up with some of this back in the 1930s. What was that again about not understanding QM?

    Negative probability. Sounds like our grocery order. There is a negative probability that we will actually receive some of the items ordered, which manifests as strange, quasi-random substitutions which propagate down the timestream and eventually result in some odd expressions at the dinner table.

    It certainly explains the results of my attempts to win the lottery.

    Just magic?

    Interesting simulations regarding time.

    The quality of the writing is quite high. That of my comprehension of this - not so much.

    Physicists have long sought to understand the irreversibility of the surrounding world and have credited its emergence to the time-symmetric, fundamental laws of physics. According to quantum mechanics, the final irreversibility of conceptual time reversal requires extremely intricate and implausible scenarios that are unlikely to spontaneously occur in nature. Physicists had previously shown that while time-reversibility is exponentially improbable in a natural environment—it is possible to design an algorithm to artificially reverse a time arrow to a known or given state within an IBM quantum computer. However, this version of the reversed arrow-of-time only embraced a known quantum state and is therefore compared to the quantum version of pressing rewind on a video to "reverse the flow of time."

    Note that the episode of "Red Dwarf" which takes place on the time-reversed copy of Earth ...has many double-reversed video versions arising on YT, wherein we can watch "Backwards" as "Edosipe Sdrawkcab" Macroscopic forward-time objects touching similar backward-time matter. (My entropy hurts!)

    And then there was "Dark" https://www.imdb.com/title/tt5753856

    Yeah, Bill. First in the Vortex and now in The Trap. Good to see you again!
