Part 4/10:
Historically, scientists held a deterministic view of physics, believing that by measuring certain properties, one could predict future states of a system. However, the discovery of quantum entanglement disrupted this notion entirely. Entangled particles remain connected, regardless of the distance, and measuring one instantaneously determines the state of the other.
Physicists have demonstrated this phenomenon over hundreds of kilometers, revealing that if entangled particles exchange information, they seemingly do so at speeds exceeding that of light. Furthermore, some argue that properties of quantum particles may only emerge at the moment of measurement. If true, this asserts that our universe cannot be both local and real; at least one of these beliefs must be false.
