Shifter is right. The subquarks exsist as sandokhan papers pointed out, but even if papers are wrong, no experiment can 100% prove something inpossible
What is wrong with some people?
Fact 1:- Subquarks were theorised in the early 1980s
Fact 2:- Subquarks have NEVER, thats NEVER, just in case you failed to see the first one, ever in the history of recorded history been discovered.
Fact 3:- Since the 1980s experiments both at CERN and Fermilab has cast serious doubt on subquarks existing.
Now it all depends if you like facts or prefer just to make things up. But those are the facts of the matter.
Some Aditional Facts
Sandokhan said subquarks were discovered at Fermilab in 1997, that is not true, he was either lying or confused.
Sandokhan later said subquarks were discovered in the 1980s!, that also is not true again lying or confused.
In case you were not able to follow that, just remember subquarks have NEVER been discovered anywhere, any time.
Its pretty simple really. If you don't believe me feel free to go look it up. Its no secret.
