Evolution of Elementary particles?

In summary, the standard model does not specifically mention a change in the ratios of fermions as the universe expands. The generations listed in the model refer to the energy required to create them and when they were discovered, not when they were created in a timeframe. As the universe expands, the ratio of fermions only significantly changes between protons, neutrons, and electrons, as all other fermions decay rapidly into one of these three or into photons.

Hello,

Maybe a strange question here (I'm not 100% current with the standard model), but does the standard model say anything about a change in the ratios of fermions as the universe expands?
(I see Generations I, II & III listed)

The generations don't refer to when they were created, as in a timeframe, but refers to the energy required to create them and when we discovered them. The ratio of fermions only really changes between protons and neutrons and electrons. All other fermions decay rapidly into one of those three or into photons.

Hrm..ok. Thank you for answering my question :)
 

FAQ: Evolution of Elementary particles?

1. What is the theory of evolution of elementary particles?

The theory of evolution of elementary particles is a scientific explanation for how particles, such as protons, neutrons, and electrons, have changed over time to form the diverse range of particles we observe today. It is based on the principles of natural selection and random mutations, similar to the theory of biological evolution.

2. How do scientists study the evolution of elementary particles?

Scientists study the evolution of elementary particles through experiments conducted in particle accelerators, such as the Large Hadron Collider. These experiments involve colliding particles at high speeds and energies, allowing scientists to observe the behavior and interactions of these particles and make predictions about their evolution.

3. What evidence supports the theory of evolution of elementary particles?

There is a wealth of evidence that supports the theory of evolution of elementary particles. This includes the observation of particle decay and transformation, the discovery of new particles, and the successful predictions made by the Standard Model of particle physics.

4. Are there any controversies surrounding the theory of evolution of elementary particles?

While the theory of evolution of elementary particles is widely accepted by the scientific community, there are still some controversies and debates surrounding certain aspects of the theory. For example, the exact mechanism of how particles acquire mass through the Higgs field is still being studied and refined.

5. How does the theory of evolution of elementary particles relate to the origin of the universe?

The theory of evolution of elementary particles plays a crucial role in understanding the origin and development of the universe. It helps explain how the universe evolved from a hot and dense state after the Big Bang to its current state, and how the fundamental forces and particles have shaped the structure and behavior of the universe over time.
