A subquark is theoretical. It's existence hasn't been proven. It may or may not exist. Your example of Earth's Magnetic Field was also theoretical until it was proven. And while the magnetic field has always existed, scientifically it wasn't proven to exist until it was. If subquarks are found to actual exist, they won't be theoretical. Until then, there is no proof of it's existence and thus only exists in theory, not actuality.
No, not how it works.
Again, using the magnetic field as an example, even before it was discovered/proven, it still existed, in reality/actuality.
Things don't just magically begin to exist when evidence of them are found.
That means subquarks either exist or they don't.
Not having evidence of their existence does not mean they don't exist.
Finding evidence of their existence wont magically make them exist.
Well looks like all the experts at CERN would not agree with you.
Really?
Or is it just your claim/interpretation of these experts that doesn't agree?
Do you have simple statements from them where they clearly say that quarks are the smallest building block of matter and that they do not have any sub-components?
If not, then again, it isn't the experts that are being disagreed with.
You misunderstand, the LHC is located at CERN.
Nope, that would still be you. CERN is an organisation, not a location.
You also misunderstand why the do what they do, it’s because we don’t know all there is to know. How could we? Why do you suppose research is ongoing is every scientific disciple?
I don’t understand why people, like get so upset over stating our current understanding of the subatomic world.
And again, that would be you.
You act like we know everything and thus us not having evidence for something means it doesn't exist.
You are not simply stating our current understanding of the subatomic world. You are stating as if there is no other possibility.
That is not how it works.
What they have found rules out the existence of subquarks. If you don’t like it tough.
Care to provide a link to this research which clearly shows (and states) that the existence of subquarks has been ruled out?
Or is this just like your claim of all those research papers which prove that gravity would cause the collapse of an infinite plane?
