Block‑universe framing enters mainstream

A leading physicist (Sean Carroll) presents the block‑universe idea — that past, present, and future all coexist — to a broad audience and links the felt direction of time to entropy rather than fundamental temporal flow. Presented in a popular outlet, this framing packages a technical physics claim as a public philosophical position about free will, moral responsibility, and historical causation. — If the public adopts block‑universe language, debates about policy, accountability, and moral agency may shift from subjective narratives to questions about physical boundary conditions (e.g., entropy sources) and institutional responsibility for future outcomes.
