Casimir effect as explanation to the Bing Bang theory

Nassims theory is that the space (sea of energy) defines the material world. I would like to ask if the dynamical casimir effect can be a explanation to the Bing Bang theory meaning that the Universe has arisen from nothing / from little vacuum energy fluctuations? Why is there rather something than nothing?

Zero in not “nothing.” It was a huge breakthrough in human history.

Using your understanding of the Casmir effect, please explain how the vacuum engineers of San Clemente will preclude supernov-ing San Clemente?
