In a new study, scientists show that two fundamental physical constants govern how runny a liquid can be. Their equation relates the minimal value of elementary viscosity (the product of viscosity and ...

Physical quantities such as the speed of light are believed to be the same independent of where and when they appear in the universe. But imagine that these fundamental constants â�" and thereby ...

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 ...
