I Are Quantum Fluctuations Valid Causes for Universe Creation?

[momo666]

You have this paper: https://arxiv.org/abs/1404.1207
I acknowledge that the "nothing" in this paper is not the "nothing" philosophers talk about.

We have the following objections:
1) Quantum fluctuations are a feature of our Universe so you can't use them as a cause for what brought our Universe into existence.
2)If this were true, we would see Universes popping our into existence all the time.

What are your thoughts?

1) Do we know that QFs were not around before the BB?
2) Frequency of new universes would be inversely proportional to the likelihood of them happening.

Take the example of a particle spontaneously tunnelling through a barrier. Sure, it happens all the time with electrons. It could - in theory - happen to a billiard ball through a pool table - but it would take longer than the lifetime of the universe to happen.

Perhaps fluctuations of a magnitude sufficient to spawn a universe only occur once every quadrillion years.

2) Universes may be popping in and out of existence all the time. If they have zero total energy, we would have no way to observe them from where we are. A billion billion universes may have been made in your finger as you type.

From a QM point of view, the probability of a anything popping into existence via a quantum fluctuation is inversely proportionate to its mass. A Boltzmann brain or massive universe, like our own, randomly popping into existence is obscenely unlikely.
