It is not the case that Rigid rods and ideal clocks are unsuitable for determining the inherent structures of spacetime postulated by the theory of relativity.

Set your confidence on the premises below to see your aggregate.
Reasons For
2 perspectives
Reason for 1 of 2
?
1.
Rigid rods and clocks, while not fundamental, serve as operationally indispensable epistemic bridges between abstract spacetime structure and empirical measurement.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
A probative system need not be relativistically fundamental to be suitable for determining spacetime structure, only reliable and systematically correctable.
?
How convincing is this?
Think about whether this reason is strong or weak
3.
Reichenbach and Bridgman's operationalist tradition demonstrates that physical coordinative definitions using rods and clocks successfully ground metrical spacetime relations in practice.
?
How convincing is this?
Think about whether this reason is strong or weak
Reason for 2 of 2
?
1.
Brown and Pooley's dynamical approach establishes that rods and clocks comportment is explained by Lorentz-covariant dynamical laws, making them legitimate trackers of spacetime geometry.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
If the behavior of rods and clocks is fully governed by relativistically well-formed laws, the ill-definedness objection conflates the instrument with the underlying physical process it instantiates.
?
How convincing is this?
Think about whether this reason is strong or weak
Reasons Against
1 perspective
Reason against
?
1.
Rigid rods and ideal clocks are relativistically ill-defined probative systems.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
Only well-defined probative systems are suitable for determining the inherent structures of spacetime.
?
How convincing is this?
Think about whether this reason is strong or weak
