Would it be safe to say that according to the standard model of particle physics all that actually exists at the most fundamental level are leptons, quarks, and bosons?
Ok. But wasn't there some talk about including gravity in the model as a boson called a graviton?dextercioby said:But the gravitational interraction between such particles is TOTALLY NEGLECTED.ABSENT,IF U LIKE.
So, in other words, you're basically saying that it's been ruled out.dextercioby said:Daniel.
The Standard Model is a theory in physics that describes the fundamental particles and their interactions that make up the universe. It is the most accepted and comprehensive model we have to explain the behavior of matter and energy at a microscopic level.
Leptons, quarks, and bosons are the three types of particles that make up the Standard Model. Leptons include electrons, muons, and taus, which are fundamental particles with no known substructure. Quarks are also fundamental particles and make up protons and neutrons, which are the building blocks of atoms. Bosons are particles that carry the fundamental forces of nature, such as the photon for electromagnetism and the gluon for the strong nuclear force.
The Standard Model explains the interactions between particles through the exchange of bosons. For example, photons are exchanged between charged particles to create the electromagnetic force, and gluons are exchanged between quarks to create the strong nuclear force. This model also predicts the existence of the Higgs boson, which gives particles their mass.
Yes, there are limitations to the Standard Model. It does not account for gravity, which is described by the theory of general relativity. It also does not explain the existence of dark matter and dark energy, which are thought to make up a significant portion of the universe. Scientists are currently working to find a more comprehensive theory that can incorporate these missing pieces.
The Standard Model has been extensively tested and validated through experiments conducted at particle accelerators, such as the Large Hadron Collider. These experiments involve colliding particles at high speeds to observe their behavior and interactions. So far, the Standard Model has accurately predicted the outcomes of these experiments, providing strong evidence for its validity.
