Ethan Siegel’s claim at Forbes: Why we’ll never exactly solve general relativity. Rob Sheldon responds

Not only is Ethan's profession about to get a major readjustment, but his attitude needs a readjustment as well. No longer can he and his colleagues hide in their ivory tower telling the world that we must leave the hard thinking to them. As many have already commented, the woke mobs are already at the gates.

An argument for the necessity of design in the universe

Arvay: Would not the multi-verse itself have to have parameters? Would not those also, have to fall within narrow ranges? And what principle of physics defines how many constants there are? What defines what ranges those parameters must have? What law of nature decides what the laws of nature must be? (That would be circular causation!) What governs the dice? Read More ›

New Scientist: Dark matter’s no-show casts doubt on Big Bang; Rob Sheldon replies

Sheldon: The recent publication of the Italians+Silk paper has now voiced the unspeakable: there is something wrong with the Lambda-CDM Big Bang model, and by inference, the 2011 Nobel Prize. Neither "dark matter" nor "dark energy" seem to exist in a form that makes the model work. Read More ›

Natural biomolecule measured while acting like a quantum wave

From the Abstract: The successful realization of quantum optics with this polypeptide as a prototypical biomolecule paves the way for quantum-assisted molecule metrology and in particular the optical spectroscopy of a large class of biologically relevant molecules. Read More ›

Sabine Hossenfelder asks, How can we test a theory of everything?

Hossenfelder: But there is no reason to think that the forces of the standard model have to be unified, or that all the forces ultimately derive from one common explanation. It would be nice, but maybe that’s just not how the universe works. Read More ›

In case you wondered why dark energy is “the biggest unsolved problem in the universe”

Ethan Siegel: Why does empty space have the properties that it does? Why is the zero-point energy of the fabric of the Universe a positive, non-zero value? And why does dark energy have the behavior we observe it to have, rather than any other? Read More ›

Rob Sheldon on whether Quanta mag’s universe is closed or flat

The result [of overspecialization], as everyone here knows, is that all biologists know that Evolution doesn't work in their specialty, but they believe it works generally for the other specialties. Every astronomer knows about the problems of Lambda-CDM model in their specialty but believes it works in the other specialties. Read More ›

Well, if the Washington Post agrees that the universe is out of whack…

Johns Hopkins astronomer Adam Riess cautions us against trying to understand what is going on: “We are wired to use our intuition to understand things around us,” Riess said. “Most of the universe is made out of stuff that’s completely different than us." Read More ›

Astrophysicist Adam Frank: Materialism is on shaky ground

Frank is an expert on the final stages of evolution of stars like the sun. His computational research group has developed advanced supercomputer tools in order to study how stars form and die. So he would incline to a materialist view, surely? But no, he says, quantum physics blew all that away. And some neuroscientists just haven’t caught up. Read More ›
