The cosmological constant has a checkered history. “It was what you could call a nonsolution to a nonproblem,” says physicist Rafael Sorkin of the Perimeter Institute for Theoretical Physics ...

It appears that we live on the knife-edge, where only the narrowest combination of values for the fundamental constants allow ...

"It could be a further hint about new physics." A changing constant Astrophysicists have been studying the fine-structureconstant ? known as the alpha constant ? for years, searching for hints ...

So it is with the “constants” of physics: Some are a lot more constant than others. In fact, physical constants run the gamut from firmly fixed to highly elusive; several are outright frauds.

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 ...

One of physics’ most fundamental constants just got a little more constant. Physicists have placed the strictest limit yet on how much the fine structure constant — which determines how ...

the researchers suggest that the difference could be real—and it tells us something about what physics might lie beyond the Standard Model. The Fine Structure Constant is a measure of ...

A fascinating paper published in Physical Review Letters this week reports that one of the fundamental constants of our universe – the fine-structure constant (α) – may in fact vary depending on where ...

The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, physicists calculate in the Sept. 10 Physical Review Letters. The new calculation ...
