Anything Quote by Lawrence M. Krauss
“To the extent that we even understand string theory, it may imply a massive number of possible different universes with different laws of physics in each universe, and there may be no way of distinguishing between them or saying why the laws of physics are the way they are. And if I can predict anything, then I haven't explained anything.”

Understanding string theory suggests countless universes with varied physical laws, making it impossible to single why our laws exist; prediction alone does not equal explanation.
In simple terms: String theory implies many universes, but prediction isn’t explanation.
Recognize limits of predictive models.
