Some reputable JFK researchers have said that this mystery will never be solved. Or did they mean the arguing will never end? These are two different things. The answer is another researcher’s question, “If it is solved, what would happen?”
The conclusion would be submitted to the real world, not the arguers. It would be analyzed by the real world and accepted as the solution by the real world. The arguers would keep on arguing as if nothing happened. Occasionally they will lash out at the solver for threatening their status quo but the arguments would continue unabated.
Yet the real world will know the party’s over.
