Part 2/8:
Quantum physics has long grappled with the concept of non-locality, a feature that challenges classical understanding of space and time. Non-locality is particularly evident in phenomena such as quantum entanglement, where two particles can become correlated in such a way that the state of one particle instantaneously influences the state of another, regardless of the distance separating them. This has led to the notion of "spooky action at a distance," a term coined by Albert Einstein, who was deeply troubled by the idea that information could move faster than light.
