String theorists delete forcibly any mention of tachyons from the equations of string theory. It is believed that the tachyon in string theory - wrong decision, the strings can not move faster than light. However, quantum mechanics for describe the phenomenon of entanglement requires a essence (particle), which moves faster than the speed of light. A tachyon (and a graviton) arose in string theory consistently, against the wishes of the researchers, as a mathematical consequence. The tachyon suggested a possible description of the mechanism of quantum correlations. Theory of Everything cannot escape the description of nonlocality.
