I said the quantum scale is unimaginably energetic but with the help of cosmological math we can get some idea.

Lets take the tiny size inside a hydrogen atom between its nucleus and the orbit of its electron. This miniscule vacuum, down on a Planke scale of 10 to the minus 33, if allowed to release all its energy at once in an expolsion would be comparable to a nuclear explosion of all the visible matter from Earth to a distance of several dozen light years being detonated as if it were all plutonium in a fission fusion reaction. That is one heck of a bang.
