People are speculating as to whether the third dimension actually exists. Not people with tragic neurochemical imbalances who would clearly benefit from some kind of medication, but highly respectable physicists. That’s not even the wildest bit. There’s a chance that this is actually testable, and that the test is within reach of our current level of technology. The device to carry it out is under active construction.
I’m dying to know what happens if the test returns positive. (My guess is “not much”, but you never know.)
