The paper defines nothing as "there is neither matter nor space or time", which sounds pretty empty to me.
It does assume that there's a quantum state that has some probability to create a vacuum bubble. They further show(*) that there's a probability for that bubble to grow exponentially.
(*) Well, that's at least what they state. My physics-fu is too weak to follow the math they show as proof.:(
