Are the fundamental constants really constant? Recent investigations have shown that one essential fundamental constant -- namely the mass ratio of protons to electrons -- can have changed only by a ...

Scientists have carried out ground-breaking experiments to investigate the atomic structure of astatine (atomic number 85), the rarest naturally occurring element on Earth. Through experiments ...

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

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 ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

The inside of giant planets can reach pressures more than one million times the Earth's atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties.

(Nanowerk News) Many substances around us, from table salt and sugar to most metals, are arranged into crystals. Because their molecules are laid out in an orderly, repetitive pattern, much is ...

Highly charged ions are a common form of matter in the cosmos, where they are found, for example, in the sun or other stars. They are so called because they have lost many electrons and therefore have ...

WE publish this week, as a special supplement, the substance of an address by Prof. N. Bohr on the development of the theory of atomic structure, and in particular of the latest form and tendencies of ...

Physicists got their first look at the structure of the atomic nucleus. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The Geiger-Marsden ...
