The most popular interpretation of the Quantum Enigma (Copenhagen) posits that a particle becomes "real" only when observed. This brings to mind a question that can be best expressed by an analogy to the macro world. During the War of 1812 the Battle of New Orleans was fought some time after a peace treaty had been signed. The combatants were unaware that the war had ended because of the communication delay. The war was simultaneously over and still in progress. The question this poses to quantum theory is would a particle that has been observed (waveform collapsed) appear real to a subsequent observer?

Predicting the weather is hard. With more data and computing power becoming available, artificial intelligence can help.
