Quantum mechanics is the most battle-tested theory in all of science. It is also practical. (One third of our economy depends on things designed with it.) But, with the advent of quantum mechanics, physicists, unexpectedly, felt the need to talk of reality, connectedness, and even “consciousness.”
Reality: Undisputed experimental results challenge any common-sense view of physical reality. By your free choice you can establish either of two contradictory prior physical realities. What existed before your observation? Experts in the foundations of quantum mechanics still puzzle about and argue about this.
While the creation of physical reality can be demonstrated only for small things, like molecules, or “simple” situations, only technology sets the limit. Quantum theory is seamless. It presumably applies to everything (including us?). Cosmologists apply quantum mechanics to black holes and the Big Bang.

Connectedness: Quantum theory tells that all things that have ever interacted are forever connected. For example, your friend’s freely made decision of what to do in Moscow (or on Mars) can instantaneously influence what you find in Manhattan. And this happens without any physical force being involved. Einstein called such influences “spooky actions.” They have now been demonstrated to exist. So far just for small things, but they are no less spooky.
Two further comments:
These two quantum phenomena are technically called “wavefunction collapse” and “entanglement.” They are NOT hard to understand–even with zero physics background. But they are almost impossible to believe. When someone tells you something you can’t believe, you might well think you don’t understand. But believing might be the real problem. It’s best to approach the subject with an open mind. This is not easy.
The facts described in our book are completely undisputed. But mentioning “consciousness” is controversial. The encounter of physics with “non-physical” stuff like consciousness has been called our “skeleton in the closet.” Look at the undisputed facts, and think for yourself about what they mean.
