“Quantum mechanics tells us that there is no such thing as a completely isolated object: objects are connected. The impression of separateness is just an illusion. It is possible for a particle to interact with another particle in such a way that the two particles form a single entangled quantum state. What this means is that the state of one particle is dependent on the state of the other in some way. Because of this dependency, it is a mistake to consider either particle in isolation from the other. Rather, we should combine the states and treat the result – both particles – as a single, entangled system. …. What this reveals is that our human perception of objects being separated is not a match with the physical reality of the situation” (Hidden in Plain Sight: the fundamental link between relativity and quantum mechanics. Andrew Thomas)
“The Particle vs. the Universe
The relationships between particles and the entire Universe are interacting with each other through their inward and outward waves. Thus they become joined into one ensemble of waves which determines the behavior of the individual particles. The simplest example is Mach’s Principle, which proposed (1890) that all the matter of the Universe determines the Law of Inertia (f=ma)” (The Eightfold Way of The Universe. Milo Wolff).
