"Adjusting its rate" would imply that there was some absolute
motion that would tell it how to adjust.
*When the ds vector is inclined wrt the time axis, all the test
particle has to "know" is how far its velocity differs from rest in
spacetime, which we know is relative. *
"differs from rest" implies there's some "at rest". The particle in
motion has many different velocities relative to many other objects. I
can't have many different time dilations at once.
*This has nothing to do with absolute anything. But I see you ignore
the more important issue; namely, how can a test particle at rest,
move at lightspeed in spacetime, *
No need to answer "How?" since it can't.
*if SR shows it can never reach that speed. And if this is mistaken,
it implies that your alleged solutions to the TP is on very shaky
ground, because it assumes what has been demonstrated is impossible. A*G
You keep referring to "solution to the Twin Paradox". What /exactly/
/is the problem/ which you think needs a solution. The fact that two
twins who travel different paths between the same two events in
spacetime measure different path lengths doesn't seem like a problem to
me. And it has nothing to do with light speed.
