A Block Is Not a Verdict
Spacetime diagrams make a block universe vivid. They do not, by themselves, decide whether all times exist, whether becoming is fundamental, or what a present means.
Thesis
The block universe is a coherent interpretation of relativistic structure, not a theorem that settles the metaphysics of time. Relativity constrains any account of becoming, but mathematical representation, physical prediction, and ontological verdict must remain distinct.
