Constants are supposed to be, well, constant. In physics there are a number of fundamental constants, such as the speed of light, Planck's constant, and the charge of an electron that are essential to ...

What is the meaning of life? Even the best of us couldn't hope to answer that question in a Universe Today article. But there ...

The fundamental constants that govern the laws of nature are being determined with increasing accuracy. A new paper outlines the proceedings from this year's Workshop on the Determination of the ...

Detecting or constraining the possible time variations of fundamental physical constants is an important step toward a complete understanding of basic physics and hence the world in which we live. A ...

Essential for life: this illustration shows how fundamental constants of nature set the fundamental lower limit for liquid viscosity. (Courtesy: thehackneycollective.com) The values of the fundamental ...

Redefinition of the kilogram will not make the kilogram more precise, but it will make it more stable. A physical object can lose or gain atoms over time, or be destroyed, but constants remain the ...

Tampa, Fla. – A fundamental number that affects the color of light emitted by atoms as well as all chemical interactions has not changed in more than 7 billion years, according to observations by a ...

While quantum physics and general relativity don't always play well together, they agree on important points, including that of the spectra of atoms. To wit: the spectrum of hydrogen shouldn't depend ...

As you dig into those mashed potatoes, be grateful the universe’s physical constants are so precise that a slight variation in any one would render that drumstick—and even your existence—impossible We ...
