Earth's Constant Hum Explained
MattSparkes writes "It has been known for some time that there is a constant hum that emanates from the Earth, which can be heard near 10 millihertz on a seismometer. The problem was that nobody knew what caused it. It has now been shown that it is caused by waves on the bottom of the sea, and more specifically 'by the combination of two waves of the same frequency travelling in opposite directions.'"
i fail it
I had a constant 50Hz hum emanating from my loudspeakers once. Swapped the brown and blue wires going to the turntable and that cured it. Reckon somebody at the factory didn't understand that the live wire should be on the INSIDE of a motor stator or transformer whenever there is sensitive electronic equipment nearby. Of course, on the Continent, they could just reverse the plug in the socket with the same effect. What's worse is I've known someone wire a high-impedance (50K ohm) mic to a preamp with about five metres of unshielded cable, running in a bundle with mains cables, and not a hint of a hum. Go figure.

Mod parents down for promoting disinformation. Cats don't purr when they're happy. Often cats will purr even when they are even severely injured. Purring actually is an indication they are feeling sociable and welcome attention. There is also some suggestion that cats use it as a healing mechanism, similar to vibration physiotherapy which actually uses similar frequencies.

Actually, the scientists HYPOTHESIZE that the hum is caused by opposing wave forces on the ocean floor, but they don't know for sure. Yet, because the church of science believes it to be true, that belief clearly trumps your shaking belief. I mean, we're as certain about this as what causes the process of evolution, and how such diverse species such as the Ampulex compressa wasp were formed by random processes in the universe.
The Shaker is all in your mind. How do we know this? Because we don't believe it, and WE are better than you and your primitive notion of the universe. Because we came up with our ideas now, and your ideas are 1000's of years old, that automatically makes our ideas more palpable and likely.
Tell your Shaker to pass the salt, so we can pour it on the wounds our grand hypothesis has undoubtedly etched into your soul. And tell Janeway to stick that up her prime directive, we need to interfere with your belief system. Why? Because it really irks us when you don't believe what we believe, because WE KNOW WE ARE RIGHT!
