Strings are so tiny, it's hard to comprehend. If an atom were enlarged to the size of the Earth, a string would only be the size of a tree. You'll need a pretty powerful microscope to get that far. In other words, a string is a millionth of a billionth of a billionth of a bi...
Quantum theory provides an extremely accurate description of fundamental processes in physics. It thus seems likely that the theory is applicable beyond the, mostly microscopic, domain in which it has been tested experimentally. Here, we propose a Gedank
In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts. Ten years later, and with the data corresponding to the production of a 30-times lar

These particles were namedelectrons.It was further learned that atoms themselves contained electrons; the electron thus became the first knownsubatomic particle.Since electrons have negative electrical charge, but the at...

Visible matter consists of atoms, and at the centre of atoms are protons and neutrons. But even these aren’t elementary particles, as detailed by the current “standard model” of particle physics, our leading description of reality on the tiniest scales. So we begin, deep dow...
