Particle physics is a mess but Hossenfelder should chill, fellow physicist says

Hmmm. He’s not giving fellow physicists much of an incentive to sort out the mess. On the other hand, civilized theoretical physicists fight so politely that you can learn a lot just by listening. Read More ›

Rob Sheldon: What that hot new quantum experiment really showed

His view: What this recent paper with a qutrit experiment shows, is that it is possible to do QM communication or QM computing at high volume and high speed. No need to wear headphones. Our view of the universe has not changed. Read More ›

Theoretical physicist: Recent claim about big quantum mechanics find is “silly”

Maybe the main thing to see here is that lots of people would love to falsify or tame quantum mechanics, the way they would like to falsify the Big Bang or fine-tuning and it won't be their fault for lack of trying. Read More ›

Astrophysicist: Nothingness” may be the answer to our cosmic questions; Rob Sheldon responds

Rob Sheldon: This article illustrates the reason why the scientific method is going extinct, not just in Darwin's circular logic, but also in physics and cosmology. Read More ›

Hope springs eternal: Are new particles hiding “in plain sight?”

The Large Hadron Collider just keeps confirming the Standard Model, almost as if there was some basis for believing it to be correct. Rob Sheldon thinks the current mood is desperation: If you don't know where you are going, you will certainly arrive. Information is finite, ignorance infinite. Read More ›

Universe a billion years younger! Scientists scrambling!! Oh, wait…

Rob Sheldon’s alternative headline for the same story: The expansion rate from Planck (68 km/s/Mpc) doesn't match the expansion rate from Hubble Easy to account for. (There are enough real mysteries in the universe without this nonsense.) Read More ›
