At Forbes: Hawking’s black hole paradox is NOT solved

Ethan Siegel looks at the limitations: But we’re still a long way away from determining exactly where that information goes, and how it gets out of a black hole. Theorists disagree over the validity and soundness of many of the methods that are currently being employed to do these calculations, and no one has even a theoretical prediction for how this information should be encoded by an evaporating black hole, much less how to measure it.

Did the black hole paradox really come to an end? Rob Sheldon offers some thoughts

Sheldon: Black Holes are a theoretical and empirical disaster. Given two possible assumptions to Schwarzschild’s solution of Einstein’s gravity equation, nearly everyone has taken the discontinuous, unphysical, "event-horizon" assumption leading to "Black Holes". One of the many predictions of BH, is that they cannot have magnetic fields, and they destroy anything that falls into them, converting all that matter into "Hawking radiation". What about all that data showing high density objects at the center of our galaxy and neighboring galaxies? Read More ›

Theoretical physicist Sabine Hossenfelder is being labelled “anti-science”

Also, let this sink in: Despite believing in determinism, Hossenfelder believes we should “decide” against a new particle collider… We can decide? On that account, to other naturalists, she is “anti-science.” Naturalism is weird like that. Eats its own. Read More ›

Physicist Rob Sheldon checks out astrophysicist Ethan Siegel for ridiculing Nobelist Roger Penrose

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. Read More ›

Researcher: We need a new Theory of Everything, one with no “things”

We’d have to guess that Stephen Wolfram’s attempt at a Theory of Everything didn’t solve all the problems. At any rate, by the time we get down to “a theory of every thing requires that one not start with a thing,” it’s not easy to distinguish science from Zen. But then maybe that’s the idea. Read More ›

Rob Sheldon on the latest effort to pretend that nothing is wrong in cosmology

Sheldon: This dashes yet another attempt to find something that the standard model could not explain. Surprisingly, this is what depresses particle theorists, who have yet to find anything new in the last 40 years, despite thousands of publications. Read More ›

Physicist: The whole universe may be a neural network

Vanchurin: “I see no reason why this process should be confined to a particular length scale and so the claim is that everything that we see around us (e.g. particles, atoms, cells, observers, etc.) is the outcome of natural selection.” It doesn’t take very long for Darwinism to become indistinguishable from magic.

Rob Sheldon on the latest claim that quantum mechanics imperils objectivity

Sheldon: Actually the debate over "the meaning of QM" has been going on since 1935 when Einstein published his EPR paper. It is just that the wiggle-room is getting reduced as our straight-jacket is being cinched tighter. Read More ›
