Many-worlds and Bell’s theorem

Schrodinger's cat in many worlds

Sean Carroll's February AMA episode is up on his podcast. As usual, there were questions about the Everett many-worlds interpretation of quantum mechanics (which I did a new primer on a few weeks ago). This time, there was a question related to the correlated outcomes in measurements of entangled particles that are separated by vast … Continue reading Many-worlds and Bell’s theorem →

Using distant quasars to close the “free will” loophole

Given the conversations some of us have had over determinism and the possibility of quantum hidden variables, I thought this was particularly interesting. In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's inequality—a 50-year-old theorem that, if violated … Continue reading Using distant quasars to close the “free will” loophole →
