This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time—the interwoven fabric ...

Particle physics invented big, global science, and national and now global facilities. If history is any guide, nothing will prevent them from answering the big questions!

For a century, quantum theory has passed every experimental test, but physicists can’t agree on how to use it to paint a ...

Researchers used Google’s quantum processor to simulate fundamental physics, offering a new way to study the universe’s basic forces and particles. The fundamental forces that shape our universe are ...

The idea is still new and requires a lot of assumptions in its calculations to make it work. Over the years, experimental results have been mixed.

A survey of more than 1,000 physicists finds deep disagreements in what quantum theories mean in the real world ...
