Part 6/11:
John Bell’s Breakthrough
The subsequent decades featured a stalemate until John Bell introduced groundbreaking ideas to test quantum mechanics. His work shifted the focus onto entanglement, explaining that linked particles could affect each other instantly, defying traditional understandings of time and space. It was Bell’s theorem that provided a rigorous methodology to assess Einstein and Bohr’s interpretations.
In the 1970s, groundbreaking experiments confirmed Bell's hypothesis, inadvertently confirming the bizarre implications of quantum mechanics. The results indicated that entangled particles exist in a probabilistic state, only acquiring definitive properties upon measurement—seemingly suggesting the universe’s reality fluctuates based on observation.
