Throughout the vacuum, electromagnetic fluctuations are produced at a constant average rate under the purview of the uncertainty principle. The name that tags these fluctuations is virtual particle production. These fluctuations in the fabric of spacetime is called “quantum spin liquid”.
Quantum spin liquids may be considered "quantum disordered" ground states of spin systems, in which zero point fluctuations are so strong that they prevent conventional magnetic long range order.
More interestingly, the vacuum as a quantum spin liquid is a prototypical example of ground state with massive many-body entanglement, of a degree sufficient to render these states distinct phases of matter.
The vacuum is completely entangled at long range as identical patterns of virtual particle emerge throughout the vacuum, with each pattern strongly entangling other identical patterns.
Just by chance, patterns of virtual particles come into existence at wide spread locations in the vacuum and become connected.
Quantum entanglement, a phenomenon in which virtual particles as fluctuations in the electromagnetic field, shed their separate identities and assume a shared existence, their properties becoming strongly correlated with one another. The virtual particles act identically no matter how far away they are separated. Normally physicists think of these correlations as spanning space, linking far-flung locations in a phenomenon that Albert Einstein famously described as “spooky action at a distance.”
Even harder to accept, there is a growing body of research investigating how these correlations can span time as well. What happens now can be correlated with what happens later, in ways that elude a simple mechanistic explanation. In effect, you can have spooky action at a delay.
These correlations seriously mess with our intuitions about time and space. Not only can two events be correlated, linking the earlier one to the later one, but two events can become correlated such that it becomes impossible to say which is earlier and which is later. Each of these events is the cause of the other, as if each were the first to occur.
But perhaps most important, researchers are working towards a new way to unify quantum theory with Einstein’s general theory of relativity, which describes the structure of spacetime. The world we experience in daily life, in which events occur in an order determined by their locations in space and time, is just a subset of the possibilities that quantum physics allows.
Some physicists take this as evidence for a profoundly nonintuitive worldview, in which quantum correlations are more fundamental than spacetime, and space-time itself is somehow built up from correlations among events, in what might be called quantum relationalism. The argument updates Gottfried Leibniz and Ernst Mach’s idea that spacetime might not be a God-given backdrop to the world, but instead might derive from the material contents of the universe.
In this view quantum entanglement is more fundamental than spacetime because quantum entanglement generates spacetime. Quantum entanglement is not sensitive to the constraints of spacetime, that is, quantum entanglement connects events without regard to walls of matter, distance or the past and future.
The key to control spacetime and the forces that operate in spacetime is the control of entanglement and coherence. This is what LENR engineering is all about.
