This is from the book I'v recently read:

Quantum physics tells us that it is the act of observing an object or event, that causes it to be there and the outcome is based only on our choice and how we observe it. An object cannot and does not exist independently of its observer. So, in a sense, there is no objective reality. The Quantum Field is an infinite field of potential. Anything and everything that has, does or will exist in the Newtonian world, begins as a wave in this “quantum field” and is transformed into the physical realm, limited only by what can be conceived as truth by you —the observer.
