Theory Quote by John D. Barrow
““For even if we expunged all the matter in the Universe the lambda force could still exist, causing the universe to expand or contract. It was always there, acting on everything but unaffected by anything. It began to look like an omnipresent form of energy that remained when everything that could be removed from a universe had been removed, and that sounds very much like somebody's definition of a vacuum.””
About This Quote
Source Book: The Anthropic Cosmological Principle, John D. Barrow, 1986
The quote describes a fundamental, all‑pervasive energy (lambda) that persists regardless of matter, resembling a vacuum energy that drives cosmic expansion or contraction.
In simple terms: A universal energy exists even without matter.
