Ethernet Cables, do they make a difference?

Gravity is unimpeachable? Says who? Gravity could easily be an emergent quality of properties of the universe we haven't developed tools powerful enough to probe yet. On the other hand, quantum electrodynamics completely describes every facet of physics that could possibly effect an Ethernet cable. The science of the electromagnetic force is unimpeachable. The science of gravity is open to broad debate. 
We've become very, very good at measuring EM phenomenon. Perhaps there's room to debate what measurements mean, but it's flat wrong to suggest there's anything about audio we can't measure WAY beyond human perception. 

@astewart8944 I would prefer an opposite example: someone puts a fancy component into the system and feels good about it, starts hearing better sound or both, good for him/her. Even if doctor says - it should not help...
Hopefully he/she did not spend a lot of money on that and no one who made a component feels like he outsmarted another customer and got easy money.

Usually when somebody presents claims of symptoms that have no basis in reality they’re treated with psychiatric medications. Is that what we should do with people who hear Ethernet and HDMI cables?

Doctors don’t just throw up their arms in frustration when faced with a difficult diagnosis and then simply write a script for psychiatric medication. Instead, they call in other physicians and scientists, often from other specialties, and they work as a team to find the answer. That’s very different from you simply pronouncing others here as crazy.

In some totalitarian systems, people who don’t conform to the government mandated norms are often labelled as crazy, and then pumped up with drugs or sent to a gulag. It sounds like you might like that kind of country - as long as you could remain in charge. Thankfully that isn’t the case here.

@kosst_amojan Because you have asked who says gravity is unimpeachable, I provide this link to Bill Nye, the science guy, and Michio Kaku, astrophysics guy, explaining that gravity is one of nature's four fundamental forces. https://www.youtube.com/watch?v=R9FVFh3HYaY
IMO when you are fighting gravity to make your point, you are probably losing ground. But, I admire your feistiness.

Bill Nye the Lying Guy is hardly any authority on science by training or trade seeing as he's a mechanical engineer. I don't think Kaku's ideas are particularly sensible either given his weird obsession with the nonsensical "many worlds" interpretation of Schrodinger. But since you feel like taking me to task on physics, I'll school you a bit. First, Leonard Suskind is really the man you want to be quoting and citing on the subject of gravity. As far as I can tell, his math and ideas on the subject are the most coherent and explanatory of the phenomenon. But even he'll tell you that gravity is by far the weakest and least understood of all the forces. The theory of gravity has no application whatsoever on the subject of audio gear either, which is why I suspect you groped for that force in particular. The other 3 forces deal with how the atoms of the gear work and transmit energy so their actually applicable to this discussion, though the strong and weak force don't really do much that requires consideration. That leaves us with EM, the most thoroughly tested and understood force. I'm not sure what you're getting at here trying to make an argument about how well proven and understood gravity is, but it's really not. It's almost a misnomer to call it a force seeing as how there's not really a force carrier particle and it may well just be an emergent property arising from dimensions of space that are obscured from our perception.
