Ethernet Cables, do they make a difference?

This has got to be one of the best deals out there for CAT7 double shielded cables:

At these prices it's definitely worth a try.

.....but gravity is questionable. Something is happening. We can accurately describe the action of the phenomenon. But nobody really knows what it is. That's what I don't understand about the point your trying to make. You made a bad analogy not very different than suggesting the earth is flat. 

John Archibald Wheeler and Kip Thorne wrote the definitive book on the subject of gravity many years ago, Gravitation, 1973, 1336 pages. Everybody and his brother now knows that gravity is actually the warping or distorting of spacetime as a consequence of mass. That’s the reason the LIGO Project detected gravity waves a couple years ago. It detected gravity waves created by a merger of two monster size black holes. The LIGO sensors detect ripples in spacetime. The head of the LIGO Project for most of its life was Kip Thorne, former student of Wheeler and co-author of Gravitation.

Addendum for the advanced student: Considering the notion that positrons were electrons that were traveling backwards in time, Wheeler came up in 1940 with his one-electron universe postulate: that there was in fact only one electron, bouncing back and forth in time. His graduate student while was a professor at Princeton, Richard Feynman, found this hard to believe, but the idea that positrons were electrons traveling backwards in time intrigued him and Feynman incorporated the notion of the reversibility of time into his Feynman diagrams.[24]

With Neils Bohr Wheeler helped explain nuclear fission.

@jinjuku what do you mean by 60% reliability?
what kind of tests did you run?

@acepilot71:

William chose the testing format. I randomly generated a sequence of cable swap out. William went with either listening to an entire track or part of a track.

He only obtained 60% accuracy of stating what cable was in use. Which means he was also in error 40% of the the time.

No. They work or they don't.  End of conversation.
