Brent,

Bravo! Someone actually registered some of my arguments, though I would state them slightly differently.

The argument in question, that everyone except Brent seems to have missed, is 
simple.

SR requires that everything moves at the speed of light through spacetime. This is NOT just "a useful myth", it's a very important fundamental principle of reality (I call it the STc Principle).

It's a commonplace in relativity texts.


This is true of all motions in all frames. It's a universal absolute principle.
Now the fact that everything continually moves at the speed of light through spacetime absolutely requires that everything actually moves and continually moves through just TIME at the speed of light in one direction in their own frame. This movement requires there to be an arrow of time,

Not exactly. It requires that there be a time-axis, but it doesn't say anything about which way the arrow points. It only implies that bodies cannot move spacelike (because when they get up to c they've used all their speed to move through space and none to move through time).

and this principle is the source of the arrow of time and gives the arrow of time a firm physical basis.

Second, because everything is always moving through time at the speed of light everything MUST be at one and only one location in time.

That doesn't follow.

That present location in time is the present moment, it's a unique privileged moment in time.

That doesn't follow.

Brent


(This argument demonstrates only there must be a present moment for every observer. The other argument Brent references is necessary to demonstrate that present moment is universal and common to all observers.) Bravo again Brent, for remembering that one too!

Since by the STc Principle everything must be at one and only one position in time and traveling through time at c in one direction, this conclusively falsifies block time.

Thus SR conclusively falsifies block time. QED.

Best,
Edgar

    Dear Edgar,

    � I will have to agree with LizR here. SR in fact makes the notion of a 
present
    moment a nonsensical concept, as SR shows how there does not exist, nay 
cannot
    exist any global frame of simultaneity. This prevents the existence, if SR 
is
    correct and good evidence tells us that it is, of any thing like a global 
present
    moment.

    � "That dog don't hunt!"

    But notice that Edgar makes two kinds of arguments:

    First, the local event argument - if two bodies interact it must be at the 
same
    moment (he neglects to to mention that it must also be at the same 
place).�

    Second, the continuity argument - if two bodies interact at two different 
events
    than at any given time between those two events both bodies exist and this 
means
    that they are existing in the same moment, even though they are in 
different places..

    Curiously, in his online blog about SR he takes the same approach as Lewis 
Carrol
    Epstein in his excellent little book "Relativity Visualized".� He notes 
that
    everything is always traveling at the speed of light.� If you're 
'standing still'
    that means you're just traveling in the time direction.� So if you move 
in the
    space direction you must give up some speed in the time direction.� 
Epstein calls
    this a useful myth and doesn't misused it.� Edgar assumes that 'time 
direction' is
    fixed like Newtonian space.
