I would say it's very important to get the physics right. Otherwise you end up with something like The Secret .

On that basis, I'd like to point out that the current consensus is that jahnauasca is completely wrong about non-locality - quantum entanglement does not permit information to be transmitted faster than light.

This is important enough that you can find several popular explanations on the internet, but I can summarise from memory.

In Bell's experiment, you place two particles in an entangled superposition. E.g. you ensure that the particles (A and B) have opposite "spin", but you don't know which is which. In fact, the particles are in both possible states at the same time, and you don't know until you look. You can separate them without looking. When you do look at one particle, the "waveform collapses" for both particles. If you found that A was "spin up" (that's the term, don't blame me), then B collapses to "spin down" at exactly the same time. But since you can't choose the state A collapses to when you measure it, you can't use it to send a message.

If someone tells you otherwise, perhaps they're trying to increase sales of their "controversial" movie .
