Essential for life: this illustration shows how fundamental constants of nature set the fundamental lower limit for liquid viscosity. (Courtesy: thehackneycollective.com) The values of the fundamental ...

For nearly half a century, theoretical physicists have made a series of discoveries that certain constants in fundamental physics seem extraordinarily fine-tuned to allow for the emergence of a ...

Detecting or constraining the possible time variations of fundamental physical constants is an important step toward a complete understanding of basic physics and hence the world in which we live. A ...

A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, ...

Billions of years ago the strength of the electromagnetic interaction was different at opposite ends of universe. That’s the surprising conclusion of a group of physicists in Australia, who have ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. One promising avenue for this sort of study is a search for changes in ...

Kwiat, D. (2026) Planck’s Constant—A Bridge to Charge and Entanglement. Journal of High Energy Physics, Gravitation and Cosmology, 12, 471-483. doi: 10.4236/jhepgc.2026.121026 .

Constants are supposed to be, well, constant. In physics there are a number of fundamental constants, such as the speed of light, Planck's constant, and the charge of an electron that are essential to ...

A bunch of the talks I went to last week at DAMOP were about searching for extremely tiny effects (I wrote about some of them, but there were a bunch more). Some of these were looking for real ...
