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 ...

An ultraprecise new measurement has given some weird particle physics theories a black eye. By measuring one of nature’s most fundamental constants more precisely than before, scientists have tested ...

The constant — the ratio of the mass of a proton to the mass of an electron — has changed by only one hundred thousandth of a percent or less over the past 7 billion years, the observations show. The ...

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.

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 ...

As given by Britain’s brilliant, opinionated Sir Arthur Stanley Eddington, the seven fundamental constants of Nature are: e, the charge of an electron; m, the mass of an electron (at rest); M, the ...

In physics, there are a host of standard constants: the speed of light, the charge-to-mass ratio of the proton, and Planck's constant, to name just a few. Repeated measurements going back a few ...

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 ...

A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, ...

If you’re confused by modern cosmology, you’re not alone. Cosmologists themselves are confused, and two new results, using very different methods, add to their collective bewilderment. The results are ...

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 ...
