Is The Future Predetermined By Quantum Mechanics?

Oct 24, 2026 · 21m

Summary

This episode explores whether the universe is deterministic by examining the intersection of Einstein’s block universe and quantum mechanics. The host analyzes how the relativity of simultaneity challenges the concept of a fixed present, contrasting the non-deterministic Copenhagen interpretation with the deterministic Many Worlds interpretation. By discussing wave function collapse and decoherence, the discussion reveals that the existence of the future depends heavily on one’s chosen interpretation of quantum reality.
