Physics is based on the assumption that certain fundamental features of nature are constant. Some constants are considered to be more fundamental than others, including the velocity of light c and the ...

The laws of physics are constant and unchanging . . . or are they? Researchers are beginning to find tantalising evidence that the physical constants of science might not be as absolute as we thought.

COSMOLOGISTS studying the rapid expansion of space through Hubble’s Constant believe they have just unlocked a fundamental secret of the universe itself. In a very Douglas Adams-esque twist, the ...

Scientists in Germany have succeeded in re-determining the Boltzmann constant. Physicists expect that in the next two years they will be able to reduce the uncertainty to such an extent that a ...

One of the most dissatisfying aspects of modern physics is the fundamental constants. It’s not that they are constant that bothers anyone, it is their very existence that is offensive to ...

One of the most exciting prospects in physics has been discovering that fundamental constants are not actually constant at all. When I first started writing, physicists and astronomers were just ...
