Spacetime loses ontological privilege
If RM were physically confirmed, spacetime would remain an exceptionally effective representation but not necessarily what the world is made of.
Consequences
If RM were confirmed
Consequences are stated conditionally; they are not presented as established facts.
Clock differences become material cadence
The observed factor is retained while its physical interpretation is shifted from time itself to the cadence of matter.
Strong-field cores
RM explores constitutively bounded strong-field branches instead of promoting mathematical divergences to realised infinities. Physical calibration remains open.
What would count as evidence?
Not a familiar phenomenon that both RM and standard physics can describe. A discriminating test requires an observable for which the two frameworks make different quantitative predictions.
