量子泡理論とでもいうのでしょうか？

(抜粋)
Quantum foam (also referred to as space-time foam) is a concept in quantum mechanics devised by John Wheeler in 1955. The foam is supposed to be conceptualized as the foundation of the fabric of the universe.[1]
Background
Quantum chromodynamics predicts that space-time is not smooth; instead, space-time would have a foamy, jittery nature and would consist of many small, ever-changing, regions in which space and time are not definite, but fluctuate.[2]:minute 48:07/1:20:00
Relation to other theories
The Casimir effect can also be understood in terms of the behavior of virtual particles in the empty space between two parallel plates.
Ordinarily, quantum field theory does not deal with virtual particles of sufficient energy to curve spacetime significantly, so quantum foam is a speculative extension of these concepts which imagines the consequences of such high-energy virtual particles at very short distances and times.
Spin foam theory is a modern attempt to make Wheeler's idea quantitative.
