Skip this question. In 1964 John Bell developed Bell's theorem that shows a difference between the two points of view. Bell's theorem established that a variable called F would have values between -2 and 2 using the local reality theory, but values outside of this range would be possible if the quantum theory was correct. Experiments to determine F began in the 1970's. A representative experiment took place in 1982.
