Even on a black hole’s turf, an essential constant of nature holds steady. According to standard physics, the fine-structure constant, which governs interactions of electrically charged particles, is ...

An ultraprecise new measurement has given some weird particle physics theories a black eye. By measuring one of nature’s most fundamental constants more precisely than before, scientists have tested ...

DESI has made the largest 3D map of our universe to date. Earth is at the center of this thin slice of the full map. The magnified section visualizes the underlying structure of matter in our universe ...

As given by Britain’s brilliant, opinionated Sir Arthur Stanley Eddington, the seven fundamental constants of Nature are: e, the charge of an electron; m, the mass of an electron (at rest); M, the ...

If you’re confused by modern cosmology, you’re not alone. Cosmologists themselves are confused, and two new results, using very different methods, add to their collective bewilderment. The results are ...

Paving the way for transforming the world's measurement system, an international task force has determined updated values for four fundamental constants of nature. Paving the way for transforming the ...

A new measurement of the fine-structure constant is three times more accurate than before. The constant helps glue together "coarse" and "fine" measurement of particles. The new measurement bests a ...
