High-precision laser spectroscopy measurements on the thorium-229 nucleus could reveal new physics, say TU Wien physicists ...

Electronics is really an applied branch of physics, so it isn’t surprising that if you are serious about your electronics, you probably know a little physics, too. If you’ve ever heard the term “fine ...

Angle of rotation: A light source (left) sends a beam of light through a topological insulator with an intrinsic magnetic field (centre), changing the direction of polarization by an angle that is ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Why is our Universe the way it is, and not some other way? There are ...

In 2024, TU Wien presented the world's first nuclear clock. Now it has been demonstrated that the technology can also be used to investigate unresolved questions in fundamental physics. Subscribe to ...

A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the fine-structure constant changes over time. The scientists from the Vienna ...

In sports and in cosmology, the rules of the game aren't supposed to change as you go along. Athletes call this playing fair. Cosmologists call it the cosmological principle, and it means that the ...

Legislators change laws from time to time, but Mother Nature's laws are eternal -- or so it has seemed. Now, though, scientists are debating clues that suggest the laws of physics change over time.

A new measurement of the fine-structure constant is three times more accurate than before. The constant helps glue together "coarse" and "fine" measurement of particles. The new measurement bests a ...

Thorium atomic nuclei can be used for very specific precision measurements. This had been suspected for decades, and the search for suitable atomic nucleus states had been ongoing worldwide. In 2024, ...

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 are those who would try to "constrain" it, at least in terms of physics. A ...
