The simplest assumption to make, following the black hole case…” quote by John D. Barrow](https://sms4smile.com/quotes/i/57a/john-d-barrow-4552_black-hole_the-success-of-discovering-a-thermodynam_2995699.jpg) [Download](https://sms4smile.com/quotes/i/57a/john-d-barrow-4552_black-hole_the-success-of-discovering-a-thermodynam_2995699.jpg) [Open image](https://sms4smile.com/quotes/i/57a/john-d-barrow-4552_black-hole_the-success-of-discovering-a-thermodynam_2995699.jpg) > ““The success of discovering a thermodynamic principle associated with the gravitational field of a black hole has led to a speculation that there might exist some thermodynamic aspect to the gravitational field of the whole Universe. The simplest assumption to make, following the black hole case, would be that it is the surface area of the boundary of the visible universe. As the Universe expands, this boundary increases and the information available to us about the Universe increases. But this does not seem promising. It would appear to tell us only that the Universe must continue expanding forever, for if it were ever to begin to recollapse the entropy would fall and violate the second law of thermodynamics. The universe can expand in all sorts of different ways and still have the increasing area. What we really want is some principle that tells us why the organization of the Universe changes in the way that it does: why it now expands so uniformally and isotropically.”” [John D. Barrow](https://sms4smile.com/quotes/author/john-d-barrow/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. The quote suggests that linking cosmic expansion to thermodynamic entropy via surface area is insufficient to explain why the universe expands uniformly and isotropically. **In simple terms:** Entropy‑area link alone can’t explain uniform expansion. Key Takeaway Seek deeper principles beyond simple entropy‑area relations. Themes cosmology thermodynamics entropy universal expansion uniformity isotropy Mood inquisitive analytical speculative Type scientific philosophical When to use this quote - research proposals - theoretical modeling - educational curricula - public outreach - interdisciplinary workshops Key Concepts holographic principle second law of thermodynamics cosmic inflation boundary conditions Questions to Reflect On - What alternative principles could govern cosmic uniformity? - How might entropy behave differently on cosmological scales? A Different Perspective The argument assumes a direct entropy‑area correspondence, which may not hold for the whole universe. ★ ★ ★ ★ ★ No ratings yet [Black hole](https://sms4smile.com/quotes/about/black-hole/) [Different ways](https://sms4smile.com/quotes/about/different-ways/) [Expanding Forever](https://sms4smile.com/quotes/about/expanding-forever-1234783/) [Success](https://sms4smile.com/quotes/about/success/) [Theory](https://sms4smile.com/quotes/about/theory/) [Thermodynamic Principle](https://sms4smile.com/quotes/about/thermodynamic-principle-4730297/) [Thermodynamics Universe](https://sms4smile.com/quotes/about/thermodynamics-universe-4730296/) [Universe Expands](https://sms4smile.com/quotes/about/universe-expands-274906/) [Universe Increases](https://sms4smile.com/quotes/about/universe-increases-2413601/) ## Related quotes > [“The universe appears to be a system of very low density wherever we look.
