    I opened up that article, and I took a look, and decided I'd better just take your word for it....

    Well, that blows up the whole premise of Back To The Future. Doesn't it? Such complexities tend to baffle me.

    I'm not laughing but I'm scratching my head. I gave the paper a quick read through and found it confounding. The publisher is the Institute of Physics. It's a legitimate physical sciences society.
    https://en.wikipedia.org/wiki/Institute_of_Physics
    Physics papers generally take a few readings until I can follow the course of the logic. This paper about spacetime is outside of my area of expertise. The paper presents a mathematical approach to navigate back to classical physics and find there a concept for the possibility of time travel, at least locally. It hearkens back to Einstein's idea that God does not throw dice and presents a view of a deterministic or at least partially deterministic universe. Quantum mechanics describes a probabilistic universe. The idea of reversing all quantum events to go back in time may be possible, but it is unlikely in the extreme. Is there a way to go back in time without doing that? The authors propose a way to think about that. Conceptualizing it is very different from doing it.

    Conceptualization is not as far out as it seems. String theory is a mathematically rigorous conceptualization. Right or wrong, it gives us a way to look at where physical laws come from. It views particles as strings with many compactified dimensions and physical forces as the ways the strings exchange information. The idea of negative mass is a conceptualization that gives us a different way to think about dark matter and energy. Personally, I find this particular conceptualization interesting. But I'm still scratching my head.

    I view this topic a bit differently from most other peole: there is no past, and there is no future.

    Sure, we have memories of a minute ago, or last week, or 1973. But the past, as an accessible domain, is gone. Poof.

    Likewise, the future does not exist until...now.

    And now.

    As soon as the future occurs, it instantly becomes the past, which no longer exists.

    We have only the now. Everything else is wish-thinking.

    Your own mileage may vary.

    I hear Tenet is more confusing than this paper.

    I'm glad the article cleared things up.

    Time is just a concept...

    It doesn't really exist ...

    The past is the future, and vice-versa...

    I agree with Peegoo...

    It's all academic until someone actually time travels and brings back hard evidence. I always liked the Futurama episode where they travel back to 1945, and Fry causes his own grandfather's death, then has sex with his grandmother, thus becoming his own grandfather, which was offered as an explanation of why he's such an idiot.

    I read that article, so everything is pretty much predestined. I don't buy it.

    Physics and math aside, dogs live in the moment and are far happier for it.

    That is exactly where I'm coming from. I ditched my TV in 2007, and I try hard to make a new friend every day.

    I majored in physics. Writing was strongly emphasized in my curriculum. That was some piss poor writing.
