Einstein asserted that no signal can be instantaneous i.e. faster than the speed of light. According to Bohr, the twin-particle system is an indivisible whole, even if they are separated by a great distance. But the connections are not 'signals' in the Einsteinian sense; they transcend our conventional notions of 'information-transfer'. EPR's thought experiment indicates that the signal between the two particles is transmitted at superluminal speed, i.e. faster than the speed of light. The concept of a "faster-than-light" communication between events, which cannot be connected by a signal (the definition of space- like), is as much a radical departure from current physical theory as Einstein's special Theory of Relativity was for the accepted (classical) physics of 1905. Nonetheless, it is logically consistent with canonical physical thought. In fact, it can be derived from the indivisibility of Planck's quantum for action, which is the basic clement of quantum theory.
Relativity permits the hypothetical existence of particles called "tachyons", which come into existence already travelling faster than light. In the formalism of the special theory of relativity, tachyons have an imaginary rest mass. Unfortunately, 11 is difficult to interpret what an "imaginary rest-mass" means in Physical terms, or what the interaction forces would be between tachyons and the ordinary particles with real rest mass.
Dr. Bell's (Dr. Bell is a physicist at the European Center for Nuclear Research (ECNR) in Switzerland.) theorem supports Bohr's position and proves rigorously that Einstein's view of physical reality as consisting of independent, specially separated elements is incompatible with the laws of quantum theory. Dr. Bell's theorem is a mathematical construct, which is indecipherable to the non-mathematician. It was reworked and refined over the following ten years, until it emerged in its present form which is dramatic, to say the least. Some physicists are convinced that it is the most important single work in the history of physics. One of the implications of Dr. Bell's theorem is that at a deep and fundamental level, "the separate parts" of the universe arc connected in an intimate and immediate way. It unambiguously proves that the Universe is fundamentally inter-connected, inter- dependent and inseparable system.
