They have a crono...have had semi-functional since the 50's...just not very usable until recently. "Crono-visor" Not at all like the movie "Contact". More like the '76 film. Truth is where you find it, and you only find it where you look. What was the purpose of gazing into a crystal ball? Why did Nostradamus stare into a silvered bowl of still water? These two examples are actually at the heart of how and why the crono works...forward and backwards.
