SUMMARY

Most quarks in the universe exist in their least massive form, specifically the up and down quarks, which are the most prevalent in nature. The discussion highlights that while higher mass quarks can be produced during rare high-energy collisions, they quickly decay back into lower mass particles. This decay process is crucial to understanding the stability of matter in the universe. The average decay times of quarks and protons are relevant factors in this context.

PREREQUISITES
  • Understanding of particle physics concepts, particularly quark generations.
  • Familiarity with decay processes in subatomic particles.
  • Knowledge of high-energy physics and collision events.
  • Basic comprehension of nucleosynthesis and its implications in the universe.
NEXT STEPS
  • Research the properties and characteristics of up and down quarks.
  • Study the decay processes of protons and other subatomic particles.
  • Explore high-energy collision experiments and their role in particle generation.
  • Learn about nucleosynthesis and its impact on the formation of elements in the universe.
USEFUL FOR

Physicists, students of particle physics, and anyone interested in the fundamental composition of matter and the processes governing the universe's evolution.

formed? I assume this has a very simple answer, I just can't seem to figure it out.

Don't you think the average time until decay is relevant? How long does it take a quark to decay? How long does it take a proton to decay?
 


So eventually everything in the universe will have decayed into the smallest possible form, assuming the universe is still around by then?
Or am I totally missing your point?
 


Ah, I seem to have found the answer to my poorly worded question.
Most of the quarks in the universe are already in their least massive generation, and these are the ones that occur most often in nature.
So I suppose the answer to my question is yes, all of the quarks are in their smallest form, and that's the way they remain, save some rare high energy collisions creating more massive quarks, which decay quickly back into a lower massed particle.
