Perhaps the deepest mystery in all of physics is quantum non-locality – the ability of two distant systems to instantaneously know about each other. Non-locality means that two particles in a quantum system can be "entangled" such that the state of one particle affects the state of the other, regardless of how far apart they are. As well as challenging our common sense, non-locality suggests that the ultimate speed limit – the speed of light – is violated. Einstein spent many years worrying about this problem because such "superluminal" interactions seem to be incompatible with special relativity.

Albert Einstein found that, for two particles coming from the same source, when the state of one changes, that of the other may change at the same time, no matter how far they are apart from each other.This superluminal phenomenon totally violates the special theory of relativity which says nothing's speed exceeds the limit of light speed, what's more, as of today, nobody has made a satisfying explanation of this strange phenomenon, not even Einstein's own general relativity.We bring forward our novel view of this long pending dilemma based on the observations of the latest physical lab reports and by summarizing various theories of information, computer science, communications, religion and physics itself.We call it Super General Relativity for now.
In classical mechanics, two (or more) systems that do not interact – that do not exert any kind of force on each other – are completely separated (see Sec. 1.1), i.e. experiments performed locally on one of them cannot in any way influence experiments performed locally on the other. Quantum mechanics, on the other hand, admits that there can be a form of interdependence even in absence of physical interaction. This type of correlation goes under the name of entanglement (see Def. 5.1: p. 183). We already know that entanglement means non-factorizability of the state vector describing a system with at least two different degrees of freedom. In this chapter, we shall see that this may be the case also for systems that are very far away (space-like distant) from each other and we shall learn many interesting consequences of this state of affairs. Recent developments show that one may entangle even particles that have never interacted with each other. The starting point of the following analysis is necessarily represented by the pioneering paper of Einstein, Podolsky, and Rosen, who inaugurated an incredible series of theoretical and experimental investigations right up to the present day that have confirmed the predictions of quantum mechanics. The “irony” of this history is that Einstein, Podolsky, and Rosen, EPR for short, aimed to present a definitive proof of the inconsistency of quantum mechanics relative to classical physical theory. In fact, they initiated one of the most prolific fields of modern science.
Quantum Non-Locality and Relativity has the rare quality of being both a significant contribution to the philosophy of physics literature and a superb introduction for philosophers unacquainted with the field. Maudlin sets out to examine the implications for our understanding of the fundamental structure of space, time, and causation of what appears to be a mysterious action-at-a-distance observed in the quantum domain. Physicists and philosophers of physics have been grappling with these implications for the last half-century, and Maudlin does a remarkable job of elucidating central themes in the literature and clarifying conceptual confusions. Throughout the book, Maudlin draws out salient points from what can easily become a morass of scientific and philosophical technicalities. At the root of puzzles concerning relativity and quantum mechanics lie a few simple experimental facts. In an experimental setup in which quantum particles begin from a common source and travel in opposite directions, distant (spacelike separated) measurements of properties of the two particles are strangely correlated. These correlations have been observed, for example, in experiments which measure polarization properties of photons. A well-known theorem due to John S. (1964) expresses a constraint on the kind of correlations that measurement outcomes in this experimental setup (known as a Bell experiment) can display, in the absence of any communication between them. The surprise is that observed correlations violate Bell's theorem, meaning that the measurement events appear somehow to be influencing each other or to be otherwise connected. But there's the rub: in experiments, measurements are spacelike separated, which means they are too far apart for any force of nature travelling at or below the speed of light to traverse the distance between them in time. Faster-than-light influences seem to fly squarely (and rather quickly) in the face of everything Einstein taught us about the structure of space and time. As it is often understood, the special theory of relativity asserts that the speed of light in a vacuum is some sort of physical limit, and that matter, energy, signals, causal influence, and the like cannot travel faster than the speed of light. Do the
Erwin Schrodinger first used the phrase “quantum entanglement” in 1935 to describe a mechanical phenomenon at the quantum level where two (or more) particles’ quantum states must be defined in relation to one another even if they may be geographically apart. This paradoxical event has confounded us for a very long time. Entangled particle behavior appears to be mysterious, illogical, and akin to sorcery at work. The successful and dependable principle of locality has led us to the achievements of twentieth-century physics. However, some theorists may doubt the locality itself due to the “spooky” and nonlocal effects of the local laws of quantum theory. Could there truly be an instant connection between two subatomic particles located on the extreme edges of the universe? Is there a theory that predicts such a relationship that is fundamentally faulty or lacking? Are the outcomes of the experiments that show this connection being read incorrectly? These questions challenge our most fundamental understanding of space and time. The universe is currently being disassembled by modern physics, and it will never be the same. Utilizing cutting-edge technology, quantum entanglement will have a positive impact on society. The history of quantum entanglement is outlined in this work, along with several hypotheses regarding the puzzling behavior of entangled particles. Quantum entanglement may also be an instance of nonlocality in action, in which what occurs in one location affects what occurs in another. Entanglement can also be compared to a situation in which a light switch is used to control two (or more) light bulbs, causing them to turn on at the same time when the switch is switched on. The key question is whether one of the aforementioned theories actually accounts for the odd behavior of entangled particles, in which case experimental evidence would unquestionably support the theory.
Abstract: The exact nature of non-locality and entanglement is still a matter of an ongoing controversy. Especially, the concept of non-locality as postulated by the orthodox Copenhagen quantum mechanics is claiming to reflect any non-locality in the quantum realm. Attention should be called to the obvious but very disconcerting fact that the concept of non-locality cannot contradict the theory of special relativity, as long as the same is not refuted theoretically or by experiments. Another way of expressing the peculiar situation is, under conditions of the special theory of relativity it remains rather discomforting to alter the properties of a distant system instantaneously (i. e. no light signal can travel) by acting on a local system. The purpose of this publication is to solve the problem of non-locality and entanglement from the standpoint of the special theory of relativity.
