I think we are, almost,

[Young Master Smeet]

I think we are, almost, argued out now.

“And I think you need to re-read it, those points are synchronous space/time co-ordinates of absolute position, in the ‘real’ universe, over time the effect does spread, and, if the universe is limited, then all points in space will be eventually effected by an event in space/time.”Well, as far as I can see, this will never happen; here is the relevant section (bold added):

Again, I think you’re misreading the light cone stuff.  Lets take a real world example.  My computer monitor is outside the light cone of my keyboard.  It is 60 centimetres away.  For2.00138E-09Seconds it is outside the light cone.  That is, the time it takes light to travel 60 cm (give or take a few extraneous quibbles).  Now, in the duration of that time period, characters cannot appear on my screen following a keystroke, because the speed of light is the cosmic speed limit of effects/information.  Characters cannot appear before I have struck a key, because that would be effect preceding cause.  Now, the key point is that time vectors can only go one way in a causal universe, we cannot go backwards in time. Now, the other point is that my monitor is 60 centimetres away in space, but it actually represents two (or more) points in space time, in this case, 60cm/0s and 60cm/2.00138E-09s.  Now, those space/time co-ordinates (and those within that range) cannot be subject to effect by electric impulses from my keyboard, and yet eventually, I am able to make characters appear on the screen.  Characters which form perfectly commonplace philosophical terms.
