yes, likewise superstring theory today. Been purely theoretical for ages, but finally possibly becoming testable at least indirectly. The most intriguing one for me is seeing if gravity square law breaks down at really small scales, indicating the existence of >3 space dimensions. (string theory predicts 6 or 7 extra, curled up really small)
