SANTA BARBARA, Calif. — The word “crisis” hung in the air from the very beginning of the meeting. In a room just steps from the ocean in Santa Barbara, astronomers and physicists shifted restlessly in ...

A new value for the Hubble constant – the expansion rate of the universe — has been calculated by an international group of astrophysicists. The team used primordial distance scales to study more than ...

Animation of the findings by researchers who used time-delay cosmography to independently confirm that the universe’s current ...

WE CAN’T ALL BE RIGHT. For something identified as a “constant,” the universe’s rate of expansion sure seems awfully inconsistent. Back in February, a team of researchers working with NASA revealed ...

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 ...

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 ...

In what scientists sometimes call “the restless universe” are a few unchallenged constants that have become the bench marks of basic research. Among them are absolute zero, which represents cold so ...

Through a variety of tests on Earth and throughout the universe, physicists have measured no changes in time or space for any of the fundamental constants of nature. When you purchase through links on ...

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...
