If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

Today’s state-of-the-art optical clocks offer accuracy to 18 decimal places, which is roughly equivalent to measuring the ...

Max Planck really kicked off a whole new way of thinking about the universe. Before him, physics was pretty much all about things behaving smoothly and predictably, like a ball rolling down a hill.

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

Planck Time is the shortest measurable moment in the Universe,just 5.39 × 10⁻⁴⁴ seconds. It’s a concept so extreme that it stretches the limits of physics and challenges our very understanding of time ...

So, you know how sometimes someone just changes everything? Like, they come along and totally flip the script on how we see the world? Well, in physics, that person was Max Planck. A lot of folks call ...

Abstract: Crystals produced from silicon that is highly enriched in the 28 Si isotope were used to determine the Avogadro constant by means of the X-ray crystal density (XRCD) method. The results were ...

We explore the sensitivity of quantum state characteristics, specifically purity and entropy, to variations in the chosen value of Planck’s constant. This investigation begins with a novel examination ...

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 ...
