Quantum Entanglement Bell Tests Part 3: The CRAP Loophole

The first three 'loophole-free' Bell test experiments were published within 3 months of each other in 2015. They claimed to have confirmed spooky action at a distance by covering all the most plausible loopholes. But by using quantum random number generators instead of using algorithms, had they simply created a completely new loophole?

Many thanks to Chantal Roth for the many discussions without which this video would never have been made.

If you want a really good explanation of Bell's inequality, and how it can be applied to an experiment, then (hopefully) you should not need to look any further.

Discover how the first Bell test experiment transformed quantum mechanics from being a fringe subject to being accepted as part of mainstream physics. The very nature of reality had been called into question, but was this justified? The evidence appeared convincing at the time, but could it be that it was not scrutinized thoroughly enough because almost everyone secretly wanted it to be true?

It was said to be the experiment that finally confirmed spooky action was real. It was claimed that the 80-year old debate was over; Einstein was declared to be wrong and Bohr was supposedly right! But how convincing was the result of this experiment? Was it really undeniable proof?

It is not easy to construct a loophole-free Bell test experiment. The scientists don't tell us about how changing any particular part of such a complicated experiment would affect the result. But isn't this exactly what the scientists should be telling us? Instead they compete among themselves to see who can produce the most impressive violation of a Bell inequality. Has proper drill-down scientific investigation (to identify a cause) been abandoned?

Beyond the scientific relevance it's also a great advance to stop all the pseudosciences that distorted QM in is favour! I' m totally fed up with the mambo jumbo of supernatural explanations... Thank you very much.
