Penrose attempts a minimalist position when defending the reality of both mathematics and the mind in a world where many believe that only the physical exists.
Holloway: There are hard, practical reasons why computers cannot understand concepts like “infinity” and “truth” and therefore cannot be conscious.
You don’t have to believe in God but that’s less complex than the typical alternatives.
Rob Sheldon: Hawking did not get the Nobel, however, because he hung his hopes on the radiation emitted by BH–the so-called “Hawking radiation”. And it was never observed. Sabine tries to explain why. But one argument that Sabine doesn’t make, is that Hawking radiation may never have been observed because BH are themselves never observed.
Sheldon: The politicization of science evidently started before Ethan’s graduate schooling, as Hoyle and his post-doc Chandra Wickramasinghe tell in their biographical writings.
It all sounds so much like religion, actually, but maybe that’s the direction in which High Science is heading.
Penrose surely offers a more thoughtful debate than Dawkins (who refused to debate Craig) and Krauss (who did but complained afterward) anyway. Too bad we had to wait till 2019 to see it.
Robert J. Marks looks at a recent theory: One issue to be aware of is this: AI is performed by computers and computers are entirely algorithmic. That is to say, they are constrained to obey a set of operations written by a computer programmer. Mathematics is algorithmically constructed, based on logic and foundational axioms. And Read More…
From previous universe: In Penrose and similarly-inclined physicists’ history of space and time (which they call conformal cyclic cosmology, or CCC), universes bubble up, expand and die in sequence, with black holes from each leaving traces in the universes that follow. And in a new paper released Aug. 6 in the preprint journal arXiv—apparent evidence Read More…
For all practical purposes. From the author of Lost in Math: How Beauty Leads Physics Astray, at her blog BackRe(Action) According to Penrose’s conformal cyclic cosmology, the universe goes through an infinite series of “aeons,” each of which starts with a phase resembling a big bang, then forming galactic structures as usual, then cooling down as Read More…
