Vor 2 Tagen · Years of conflicting neutrino measurements have led physicists to propose a “dark sector” of invisible particles — one that could simultaneously explain dark matter, the puzzling expansion of the universe, and other mysteries.
Vor 10 Stunden · Dark matter can refer to any substance which interacts predominantly via gravity with visible matter (e.g., stars and planets). Hence in principle it need not be composed of a new type of fundamental particle but could, at least in part, be made up of standard baryonic matter, such as protons or neutrons.
Vor 2 Tagen · Richard Phillips Feynman ( / ˈfaɪnmən /; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he prop...
Vor 3 Tagen · Atoms are the basic particles of the chemical elements. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms.
Vor 5 Tagen · The Particle Physics Collaboration (PPC) group pursues the completion the of Standard Model of particle physics, a set of theories which describe all known phenomena concerning the electroweak and strong interactions, and explores physics beyond the Standard Model.
Vor 4 Tagen · Wave-particle duality is the term for the fact that fundamental objects in the universe such as photons or electrons appear to exhibit aspects of either waves or particles depending on the experiment.
Vor 4 Tagen · The Large Hadron Collider (LHC) was constructed by the European Organization for Nuclear Research ( CERN) in the same 27-km (17-mile) tunnel that housed its Large Electron-Positron Collider (LEP). The tunnel is circular and is located 50–175 metres (165–575 feet) belowground on the border between France and Switzerland.
