Physics Says Your Previous Is Still Taking Place-- The Block Time Lie Explained
Does time actually flow? Physics says no. Your past isn't gone-- it's a slice of spacetime you'll never ever stop occupying. Einstein's relativity ruins the universal "now." Quantum mechanics won't wait. Entropy discusses the arrow. Great voids conceal information. Spacetime might emerge from entanglement itself.
TL; DR: Relativity eliminates the universal "now." The block universe is genuine-- your past, present, and future all exist all at once. Quantum collapse doesn't bring back flowing time. Entropy develops the arrow (why you remember breakfast, not supper). Free will survives determinism through compatibilism. Great void horizons fracture "now" into observer-dependent slices. Spacetime might emerge from entanglement and quantum error correction. Your brain develops the sensation of circulation by reading records along your worldline. Duty and significance reside in how you form those records-- not in metaphysical flexibility.

WHAT YOU'LL LEARN:. ✓ How relativity damaged the universal "now" (Minkowski spacetime geometry). ✓ Why the block universe is genuine and what it means for grief, memory, identity. ✓ How quantum mechanics fails to restore a streaming present (collapse, many-worlds, decoherence). ✓ Why entropy develops the arrow of time (thermodynamics, second law, info). ✓ How free choice survives determinism (compatibilism, agency, obligation). ✓ Whether quantum gravity breaks spacetime apart (Wheeler-- DeWitt, loop quantum gravity). ✓ How calculation may render reality (cellular robot, tensor networks, holography). ✓ What great void horizons reveal about info, death, and the firewall software paradox. ✓ Why cosmic time and your personal time are essentially different. ✓ How to live meaningfully in a frozen, eternalist universe.
