Nothing Can Move in Spacetime
Louis Savain,
General Relativity and Time Travel
There is a common thread that weaves itself around time travel theories and their authors' arguments. It is Einstein's theory of relativity and, in particular, the general theory of relativity. For close to a hundred years relativists have claimed that there is a time dimension (i.e., a degree of freedom on a par with the other three spatial dimensions) and that gravity is due to bodies following their geodesics in curved spacetime. In other words, relativists believe in time travel in one direction, toward the future. They continue to teach the same fallacy in countless books, articles, peer-reviewed papers and physics classes around the globe at this very moment. They do it even in the face of irrefutable arguments that show that motion in spacetime is logically impossible. Spacetime is frozen from the infinite past to the infinite future by definition.
Of course, when this is pointed out to them, the usual response is either outright denial or a mountain of obfuscation. When push comes to shove they will insist that physicists mean something different when they speak of motion in spacetime. Never mind that motion has always been defined as a change in position in a coordinate system. This definition of motion has not changed in millennia.
Simple Proof that Nothing Can Move in Spacetime
Why is motion in spacetime impossible? It has to do with the definitions of space and time and the equation of velocity v = dx/dt. What the equation is saying is that, if an object moves over any distance d x, there is an elapsed time d t. Since time is defined in physics as a parameter for denoting change (evolution), the equation for velocity along the time axis must be given as v = dt/dt which is self-referential. The self-reference comes from having to divide dt by itself. dt/dt always equals 1 because the units cancel out. This is of course meaningless as far as velocity is concerned.
To emphasize, it is logically impossible for the t coordinate of an object to change because such a change is self-referential. Et voilà! It is that simple. No time travel, no motion in spacetime, no spacetime and no time dimension. They are all abstract mathematical constructs without any counterpart in nature.

If I'm understanding what I read (which I may not have), I can't help but think its a bunch of hogwash seeing as God has years and years are a measurement of time. So how can time just be a mathematical abstraction?
To quote ray:
http://forums.bible-truths.com/index.php/topic,10538.0.html ------------------------------------------------------
Psa 102:25 …and the heavens [are] the work of Your (Comment: This is speaking of God.) hands.
v. :26 They shall perish (Comment: What? The heavens and the earth.), but You shall endure: yea, all of them shall wax old like a garment; as a vesture shall You change them, and they shall be changed:
v. 27 But You [art] the same, and Your years shall have no end.
Didn’t we read from both of these people that when the creation is done away with that there will be no time? When there is no sun will there be years? No? “All of them shall wax old like a garment; as a vesture shall You change them, and they shall be changed: But You [art] the same, and Your YEARS shall have no end.” “Shall have” present progressive into the future, “no end.”
Didn’t J. Preston Eby say that the way to tell if the Bible is talking about something that continues, the Bible uses the phrase “no end?’ I read that right at the beginning, he knows that. Here’s one that says, the years of God. You say, ‘well it’s talking about spiritual years.’ It doesn’t matter, he uses the word “years, shall have no end.” Who you going to believe the Bible or theologians, Christian ministers.

Now perhaps I misunderstood the small snippet you provided but that's how it came out to me.
God bless,

Hi Alex,
I think that the author was referring to "time travel" being a mathematical abstraction.
So then we live in time, but always in the present time. What has gone before is lost to us for all time, OTHER than in our limited memories. We cannot go back and change it. AND neither will God go back and change it or erase it to provide us with a clean conscience.
We have to depend upon the blood of Christ to cover our sins even though God can forgive them and forget them and put them far from us. Our history is still our history and we cannot pretend we did not sin or that we are somehow superior to others.
Of course God does not have a limited memory... God can recall every atom of our being and how it was/is put together and is able to resurrect us exactly as we were. (smile)
HOpe that helps, Ibob

I found this fellow Louis Savain intriguing after visiting his web site. I may read more and give you all my take on it, for what its worth. Many kooks out there. Is is he one. I will find out. :)

Thanks for clarifying bob!
Was there more to the article or was it just that short paragraph?
