>we cannot properly measure the quark's properties
>therefor their intrinsic property is that they have uncertain properties

This is basically considered a fact now and i mean, how the fuck do we know that it's not just false measuring? It seems like grug saying "hey we can't measure when it will begin raining so its intrinsic property of rain that it falls according to sacred pink fluffy snake's will".
Is there any actual evidence to why this is true? Quantum tunneling should be proof but i cannot find any successful tunneling experiments either.
