The hypercharge of a subatomic particle is the sum of its baryon number and its strangeness. Strangeness and the baryon number are properties of subatomic particles. Since strangeness and baryon number are conserved, the hypercharge is conserved as well. These particles are now considered the building blocks of the Universe. My science teacher doesn't know about it and needs proof.
Gluons are the force particles which hold quarks, another subatomic particle, together.
Gamma rays are photons, which means they have no mass and no charge, since they have no protons, neutrons, or electrons. I was wondering about the string theory. Within the last 20 years, the string theory has become the leading theory to describe the fundamental particles and forces in nature. The string theory is based on the premise that at an extremely small scale, particles are actually one dimensional extended objects. All objects such as quarks are made up of these strings.
