The quantum properties of non-point particles

Quantum theory: it’s unreal We know that everything in the universe including particles have physical size. Even so for the past 50 years, the Standard Model of particle physics which many say has given us the most complete mathematical description of the particles and forces that shape our world ignores this fact and treats them […]

The post The quantum properties of non-point particles appeared first on The Imagineer's Chronicles.

Ethan Siegel: Why there is more to universe than the standard model

At Forbes: While experiments are telling us that low-energy supersymmetry and extra dimensions probably don’t exist (or are so constrained that they’re irrelevant), there are plenty of pieces of evidence that there’s more to existence than the Standard Model alone. What else is out there? There are five strong, independent lines of inquiry that reveal […]

Incorporating gravity into the symmetry of the Standard Model

For the past 50 years, the Standard Model of particle physics has given us a complete mathematical description of the particles and forces that shape our world with the exception of gravity.  It predicts with so much accuracy the microscopic properties of particles and the macroscopic ones of stars and galaxies that many physicists feel […]

Scientific American: Dark matter explanation flawed, but what should replace it?

From Lee Billings at Scientific American: Whatever dark matter is, it is not accounted for in the Standard Model of particle physics, a thoroughly-tested “theory of almost everything” forged in the 1970s that explains all known particles and all known forces other than gravity. Find the identity of dark matter and you illuminate a new […]

FYI-FTR: Luke Barnes on Fine Tuning and the case of the fine structure constant

It seems there is now a talking-point agenda to dismiss the fine tuning issue as an illusion. So, in the current thread on the big bang and fine tuning, I have clipped and commented on a recent article by Luke Barnes. However, comments cannot put up images [save through extraordinary steps], so it is first […]
