At a fundamental level, our Universe is made of particles, forces, interactions, and the fabric of space and time. Spacetime forms the ever-evolving stage on which the play of the cosmos unfolds, ...

From a physics perspective, it's long been assumed that the fundamental constants and the laws of nature really are the same everywhere and at all times. However, one particular dimensionless constant ...

Physical quantities such as the speed of light, the gravitational constant and the electron mass are believed to be the same independent of where and when they appear in the universe. Therefore, they ...

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 ...

The cosmological constant enters Einstein’s field equations as a uniform energy density permeating spacetime, and its observed value underpins the accelerating expansion of the Universe. This ...
