@serenade, I don’t think pseudoscientific ideas are worth considering, I think people like the author you cited are typically frauds, and I think people who believe them are gullible dupes.
And pseudoscience and fraud do indeed make me unhappy, partly because the truth is more wonderful and amazing (and mysterious) than even the frauds imagine.
Let me explain. Here is what the uncertainty principle says: The question “what is that particle’s position and momentum” has no answer. In other words, it’s like asking how many sides a square triangle has, or how many fingers a bacterium has. At the scale of particles, stuff just doesn’t work that way.
Particles are, fundamentally, “waves of probability.” These waves interfere with each other, just like ocean waves.
When we talk about “observing” something, we actually mean a complex physical process. The process involves photons—particles of light. You “observe” something by bouncing photons off of it. The photons enter your eye, your retina produces a nerve impulse in response to the pattern of photons, and that impulse is decoded by your brain. That’s all a physical process involving a ton of different quantum particles.
But if those particles are all really just “waves of probability,” that means that the photons that you’re bouncing off something to “observe” it can interfere with that same something, just like waves. All this means that the observer cannot be separate from the thing he or she is observing in quantum mechanics. The observer and the thing being observed must be treated as part of the same system. That system consists of waves of probability, overlapping and interfering. And the act of observation can change the pattern of waves.
Now, this is all weird and amazing and has many practical effects (your computer is built on these principles). But it has absolutely nothing to do with bringing things into existence by imagining them. We are talking about single photons and electrons. You cannot bring an electron into existence by imagining it. Likewise, you cannot talk to dead relatives through crystals. The concept has literally nothing to do with the science.
Anyone who says you can is selling something.
