We carry out a thought experiment in an imaginary world. Our world is both local and realistic, yet it violates a Bell inequality more than does quantum theory. This serves to debunk the myth that equates local realism with local hidden variables in the simplest possible manner. Along the way, we reinterpret the celebrated 1935 argument of Einstein, Podolsky and Rosen, and come to the conclusion that they were right in their questioning the completeness of the Copenhagen version of quantum theory, provided one believes in a local-realistic universe. Throughout our journey, we strive to explain our views from first principles, without expecting mathematical sophistication nor specialized prior knowledge from the reader.
我们在一个虚构的世界中进行了一个思想实验。我们的世界既是局域的又是实在的，但它比量子理论更违背贝尔不等式。这以尽可能简单的方式揭穿了将局域实在性等同于局域隐变量的神话。在此过程中，我们重新诠释了爱因斯坦、波多尔斯基和罗森1935年著名的论证，并得出结论：如果有人相信一个局域实在的宇宙，那么他们质疑哥本哈根版量子理论的完备性是正确的。在整个过程中，我们努力从第一原理出发解释我们的观点，不期望读者有数学上的复杂性或专业的先验知识。
