A fundamental constant of the universe may not be so constant after all, according to a new study. Recent observations of distant galaxies suggest that the strength of the electromagnetic force the so ...

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 ...

Electrons are influenced by a magnetic field display known as the quantum Hall effect (QHE), which helps scientists make hyper-accurate measurements. Now, scientists have observed a similar behavior ...

These universal constants include the speed of light in a vacuum, Newton’s gravitational constant, Planck’s constant (the scale at which quantum effects begin), and the masses of the fundamental ...

For nearly half a century, theoretical physicists have made a series of discoveries that certain constants in fundamental physics seem extraordinarily fine-tuned to allow for the emergence of a ...

The idea that fundamental constants do not actually stay constant over space and time has long played on the mind of physicists. But by looking at how a distant galaxy has absorbed the light from 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 ...

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 ...
