Recent findings suggest that the fundamental constants may not be as stable as we assumed. The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, ...

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 ...

Public confidence in the "constants" of nature may be at an all time low. Recent research has found evidence that the value of certain fundamental parameters, such as the speed of light or the ...

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 ...

Sound has a speed limit. Under normal circumstances, its waves can travel no faster than about 36 kilometers per second, physicists propose October 9 in Science Advances. Sound zips along at different ...

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 ...
