How can be sure than the unique stable particles are the neutrons, the electrons, the photons and the neutrinos? Couln´t it be possible than at low energies were there more particles??
Sorry, I copy and pasted from jtbell's link...mathman said:1033 and 1034 should be 1033 and 1034.
Stable particles are elementary particles that do not decay or change into other particles. They are characterized by having a long lifetime and a constant mass.
Neutrons, electrons, photons, and neutrinos are all stable particles, but they have different properties and roles in the universe. Neutrons and protons make up the nucleus of an atom, while electrons orbit around the nucleus. Photons are particles of light and carry energy, while neutrinos are neutral particles that interact weakly with matter.
Neutrons and protons provide the strong nuclear force that holds the nucleus together. Electrons provide the electromagnetic force that keeps atoms from collapsing. Photons carry the electromagnetic force and allow for energy transfer. Neutrinos play a role in nuclear reactions and have a stabilizing effect on the universe as a whole.
Stable particles have numerous applications in everyday life. Electrons are used in electronics and power generation, while photons are utilized in lighting and communication technologies. Neutrons are used in nuclear power and medical imaging, and neutrinos are used in particle physics research and may have potential applications in communication and energy production.
Yes, scientists are constantly studying and researching stable particles to better understand their properties and interactions. This knowledge can lead to advancements in technology, energy production, and our understanding of the universe. Ongoing research includes studies on the nature of neutrinos, the properties of dark matter, and the behavior of particles at high energies.
