Latest Physical constant Stories
The electromagnetic force has gotten a little stronger, gravity a little weaker, and the size of the smallest "quantum" of energy is now known a little better.
An international team of astronomers has looked at something very big -- a distant galaxy -- to study the behavior of things very small -- atoms and molecules -- to gain vital clues about the fundamental nature of our entire Universe. The team used the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) to test whether the laws of nature have changed over vast spans of cosmic time.
Physical constants are one of the cornerstones of physics -- sacred numbers which we know to be fixed -- but what if some of these constants are changing? Scientists have discovered that one of the constants of the universe might not be constant.
