Is it tho? Correct me if I'm wrong but black holes, although pretty whimsical when first proposed, are an explanation for aspects of general relativity with indirectly observable phenomenon, not speculation on how aliens derive energy. It's important to recognize and push through biases and recognize there is a role for theoretical work but theoretical or particle physics is different to whatever encompasses Kardashev scales, Dyson spheres and other thought experiments. I think I'll just agree to disagree here.
