Part 6/10:
Einstein's skepticism toward quantum mechanics led him to contend that hidden variables might underlie quantum entanglement. Yet, with the recent achievements of scientists like John Clauser, Alain Aspect, and Anton Zeilinger, the existence of such hidden variables has been largely dismissed. They have arrived at a crucial understanding: particles lack fixed properties until measured. This phenomenon has led to speculation regarding the actual existence—and nature—of reality itself.
