AFAIK, the theory is not able to make _any_ predictions yet.
It purports to be one of those "theories of everything" in the form of a kind of "universe building kit".
But all it produces are a bunch of pretty "hypergraphs" that have some loose analogies with some physical theories.
If, at the end of the day, one's "theory of everything" can't replicate classical mechanics, the spectra of Hydrogen atoms, and the laws of thermodynamics, then it probably doesn't warrant bloviating on the big bang, black holes and information theory as Mr Wolfram is apt to do.
