Keywords:

  • controlling the connection - signals, and Bohmian mechanics;
  • transmission of energy, faster than light - threat to physical theories;
  • relativity, implying - constraint on speed with which signals, being sent;
  • violation of inequalities - not per se implying any ability of sending signals;
  • non-relativistic quantum mechanics time order - one which gets to its polarizer first being “first”;
  • David Bohm's picture of reality - underlying quantum phenomena;
  • Relativity demands, impossibility of superluminal signaling - violation of Bell's inequalities;
  • Bell's theorem again - space-time diagram of experiment on pair;
  • factorization, key to deriving inequality - and careful analysis;
  • signaling paradoxes, and superluminal signals - signal received before it is sent
