Multiversum oder Anti-Universum: Neue Theorie legt nahe, dass die Expansion des Universums mit einem Anti-Universum verbunden sein könnte

Are there any testable aspects of this theory? I couldn’t find any in the paper, but I’ll admit to skimming once I saw that the premise is based on the Quantum Focusing Conjecture (QFC), which also seems to be speculative physics.
