A mysterious new shape seems to say something fundamental about the nature of the universe. Can we understand its message?

Plato set out to explain everything with five perfect shapes. His theory died centuries ago. But in 2013 a shape called the amplituhedron burst upon the science scene. Physicists find it performs a miracle. But they don’t know how. The answer may hold a deep truth physics can sense but can’t quite find. Understanding the […]

Planck-scale physics needs to start with the beginning of the universe just like quantum theory started with the hydrogen atom

Planck-scale physics is not yet in its infancy. It is in gestation. Arranging a successful birth requires a strategic discipline. Walk before you try to run! For some reason (we will get to that) physicists seem doomed to run. Indeed—to milk the metaphor for maybe more than it is worth—they essay hundred-meter sprints before they […]

Twist and Shout: Topology In Action

As Chubby Checker sang and showed a 1960s generation, “Let’s do the twist.” Twist is not only an important thing. It is the only thing. Look around; all that you can see is made of twist. How so? The explanation starts with atoms and takes us through topology and Solitaire to the final fate of […]

The Beginning of Time

When did time begin? Science now has an answer. How did time begin? For millennia this was a subject for speculation, little of it based on science. But there is now a philosophic answer. Space came first. Time began soon after space. Very soon. Here’s how. From recent measurements we know that time began 13,799,000,000 […]

Exotic Not-Erotic Hadrons vs Gravitational Ripples

I’m taking time out from Pristina. Exotic hadrons are the rage this week. Suddenly a cipher, Z(4430), seems to be sexy. What’s exotic? Well, not-exotic, plain-vanilla hadrons are particles of matter. They include baryons―the protons and neutrons that are stable in nuclei of atoms that we see, and unstable particles called mesons that fly unseen […]
