That's a paraphrase of the theory of James Hartle, who is so smart that he got first billing for the Hartle-Hawking function.

This universe is so wonky that it needed a secondary universe that appeared and disappeared in an instant in the Big Bang that would allow quantum tunneling to create this persistent universe.

But even Hartle couldn't explain dark matter. It doesn't exist. It's a math mistake that comes from the assumption of lightspeed invariance, which is rejected by the growing alternative called stochastic electrodynamics (SED). The error arises from believing in an old universe, and then wondering why galaxies still stick together so nicely instead of being random as the old-earth theory predicts: it yields the wrong total mass calculation and so new dark entities are invoked to explain the error away. If you reject the assumptions of new quantum physics conspiratorially circulated by Bohr, SED allows all phenomena to be explained without quantum uncertainty and without epicycles. Then the unexplained unexpected attraction is explained easily by the accretion theory of coalition of plasma strands that also accounts for why all spiral galaxies haven't self-randomized.

Genesis Creation is the only big bang that works. As pointed out in this thread, all other theories have an age crisis in which the stars are older than the universe containing them. "13.7 billion" is a compromise number that assumes that one or more calculations leading to the compromise are mistaken and the error will appear in time and refine the number. Well, maybe the number is .000006 billion as consistent with Joao Magueijo's CDK proposal.
