Finding new physics: How to get a big bang for our bucks

Physics has a big problem: How should it decide what avenues to new fundamental physics to explore? The problem is invisible but affects our lives. We could start to fix it if non-physicists—who pay the bills and stand to reap the benefits—recognize it is our problem and also our opportunity: The fix could be worth […]

Black hole mystery finds an original solution

“BLACK HOLE MYSTERY” says the cover of a recent Scientific American. “The first supermassive black holes formed earlier than seems possible.” The author is Yale astrophysicist Priyamvada Natarajan. “What are scientists missing?” the cover asks. Maybe the answer is: A grasp of quantum space and the topology of twist. It’s a massive problem in more […]

What are the quanta in quantum gravity? A hundred years ago Einstein said “space”. So where are we now?

Quantum gravity is all the rage in physics these days. There are books about it but none say what quantum gravity is. And none report real progress. We should be upset about this. Really! Quantum gravity tries to reconcile our two immensely successful—but mutually inconsistent—theories about the world: quantum theory and relativity. A quantum theory […]

How does Planck-scale physics work?

Planck-scale physics is more than a hundred years old. Physics is starting to take it seriously. This is great because we can hope for exciting new science and technology to drive a new economy. Planck scale is the incredibly tiny scale at which physics actually happens. It is the scale at which space no longer […]
