The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

The four fundamental forces act upon us every day, whether we realize it or not. From playing basketball, to launching a rocket into space, to sticking a magnet on your refrigerator - all the forces ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

Today's physicists are struggling with a quandary. They have accepted two separate theories that explain how the universe works: Albert Einstein's general theory of relativity, which describes the ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. What is the Universe, at a fundamental level, truly made out of? Is ...

Scientific understanding proceeds by fits and starts, with an occasional detour down a wrong path. However, today the world’s physicists have a real advance to celebrate. They have observed the most ...

The experimental neutrino physics group is involved in three experiments around the world, described below. Our research involves the study of fundamental subatomic particles called neutrinos. In ...

Gravity is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or the moon causing ocean tides. Gravity is ...
