    Do the problem as if track 1 is shorter than a kilometer and see if that makes a difference.

    Quick answer on big bang theory: Newton's third law is almost irrelevant to whether or not there is expansion but it plays a role in slowing down. The law is about forces, and thus about the...

    I'm of the opinion that McTaggart was also doing textual analysis and that the A-series/B-series distinction is misleading. It does give one a place to start, however.

    Sadly, I cannot use your strange definition of "static" and I do not recommend that others do either. Like I said, every description of movement uses spacetime, so unless every description of...

    I don't know what that means. It seems that according to SR, there is nothing real about a system of coordinates, just physical rules relating how systems behave. I don't know how to identify...

    A relativistic presentist does not grant that things that are spacelike separated from an event need to be real to that event in some sense other than outlined in their pre-estbalished causal...

    That might make sense if we say that every description of motion is a block-universe model. However, it would be foolish to do so. It is also possible to use spacetime to describe the state of...

    You are being vague, but what you are really saying is that there is one time and space and that all the effects of special relativity are an illusion caused by the changes to the speed of light...

    An interesting idea. It is possible for an atom to absorb light and then convert that energy into kinetic energy, but seemingly this would have a limit. If the atom ran into something else, it would...

    I agree: if you want the sort of physics that Farsight offers, put me on ignore.

    You mean, stay on topic and not avoid the inconvenient questions?


    OK, so then we have to explain why all these things obey the same changes of time. If we just accept that there is time in...

    This is a great example of you cherry-picking quotations to make a claim about an author that is not true.

    Now I wouldn't think that you are lying about this author, I would think that you did not...

    OK, so then we have to explain why all these things obey the same changes of time. If we just accept that there is time in spacetime, then we can explain how the timing of all things work out fine....

    Then you have a number of tasks to do.

    1) Show that everything is light. (A fairly difficult task, since contemporary physics rejects this claim.)
    2) Show us a definition of motion that does not...

    I don't see why that's funny.

    One can certainly perform a measurement to verify a value in a coordinate system, but a transformation is not a measurement. It takes a value, which may have been...

    You have claimed before that there are these people. Please produce a citation.

    Clearly you are lying.

    I made no mistake, I merely wrote the facts of the matter about General Relativity. I did...

    I have heard the claim that motion is empirical. However, the only way I know of for testing claims about motion involve comparing different locations at different times. Every test of general...

    He can't ruin the articles, he can somewhat tarnish the reputation of the authors to the extent that they are identified with Farsight. I don't think that's too much, though.

    No, as you often quote, Einstein said, "a curvature of rays of light can only occur when the speed of light varies with position". This does not imply cause. If you think that there is a cause, then...
