I know you’ve been searching for Tachyons for a long time; but one audacious woman claims to have finally detected them.
Watching the PBS documentary on Michael Greene’s The Elegant Universe. It’s fairly well done, though a bit slow and repetitive.
The most common criticism I’ve heard of string theory is that it is not really scientific at all, because it makes no testable predictions. This lack of observability and predictive power makes it completely useless, “not even wrong”. Greene insists that tests will emerge in the future. But the documentary makes the claim that string theorists predicted the existence of a gravity-particle in the 1980’s; and there are now experiments designed to detect these “gravitons” and “gravity-waves” (like LIGO ) I would think this is a great test, except that they completely fail to mention it in the documentary.
