A Supposed alternative to GR I feel to be NonsenseClarification please

  1. Sep 19, 2005 #1
    Hello, I stumbled upon this work some time ago. It is based on the k-calculus and claims to be a viable alternative to GR. It seems to me to be a whole load of arm waving and even exagerated claims. I am no expert on this though and so would like some more knowledgable opinions on whether the paper should be taken seriously.

    K-calculus is fine and well established as a way to understand special relativity.

    As far as geometric optics goes, I'm not terribly familiar with it, but the paper itself gives us a Big Clue.

    It's nonsense IMO. K-calculus has big problems in GR. That is, btw, a personal opinion and does not represent the views of PG management.

    The first on the reference list (other than to his own work) is:

    [6] Tom Van Flandern. The speed of gravity – what the experiments say.
    Phys. Lett. A, 250:1–11, 1998.

    Not really helpful if one proposes an alternative to GR.....



    Regards, Hans

    K-calculus == special relativity, not general relativity, at least in its standard form. Let's not through out the baby with the bathwater - K-calculus is a perfectly fine way to understand SR. One of the benefits of the K-calculus approach is it's simplicity - it doesnt' require more than high school math, so it's a good way to teach SR to high school students.
