Researchers in quantum gravity and quantum cosmology, show how observers influence the structure of our reality. Observers can dramatically affect the behavior of observable quantities both at microscopic and massive spatio-temporal scales. The world is not something that is formed outside of us, simply existing on its own and observers ultimately define the structure of physical reality itself. A network of observers is necessary and is inherent to the structure of reality. Observers live in a quantum gravitational universe and come up with a globally agreed-upon cognitive model of reality by exchanging information about the properties of spacetime.
Once you measure something the wave of probability to measure the same value of the already probed physical quantity becomes localized or simply collapses. That’s how reality comes to be consistently real to us all. Once you keep measuring a quantity over and over, knowing the result of the first measurement, you will see the outcome to be the same. In quantum terms, an observer influences reality through decoherence, which provides the framework for collapsing waves of probability, largely localized in the vicinity of the cognitive model which the observer builds in their mind throughout their lifespan.
