Standard Model

CREATED BY chris • LAST EDITED BY chris 8068 days AGO

Highlight of 1970s physics. Explains quite a few features of the world with just 6 Quarks, 6 [create Leptons] and [create Force Carrier Particles] (like photons) — the Elementary Particles. Doesn't explain gravity, tho.

2002: "The standard model was designed within a framework known as Quantum Field Theory (QFT), which gives us the tools to build theories consistent both with quantum mechanics and the special theory of relativity. With these tools, theories were built which describe with great success three of the four known interactions in Nature: Electromagnetism, and the Strong and Weak nuclear forces. Furthermore, a very successful unification between Electromagnetism and the Weak force was achieved (Electroweak Theory), and promising ideas put forward to try to include the Strong force. But unfortunately the fourth interaction, gravity, beautifully described by Einstein's [create General Relativity] (GR), does not seem to fit into this scheme. Whenever one tries to apply the rules of QFT to GR one gets results which make no sense. For instance, the force between two gravitons (the particles that mediate gravitational interactions), becomes infinite and we do not know how to get rid of these infinities to get physically sensible results."
