This has been falsified time and again, most recently by the LHC not generating microscopic black holes.
Is that the case? I’m not an expert, but I’m under the impression that the LHC was predicted to generate microscopic black holes only for somewhat large compactified dimension size (i.e. millimetres), and even string theorists wouldn’t have thought of that as particularly likely.
Right, I should have phrased it better. It puts tighter constraints on extra dimensions. The string theory itself says nothing about the expected size, so the tighter the constraints, the less likely string models are correct.
