This theory is still being contested, with the Scottish Society for the Prevention of Cruelty to Animals claiming there isn't enough evidence yet to come to a conclusion. But if it's a contest of doggy will between sniffing smelly butts and ghosts whispering "Here boy," it seems obvious.
The Hum That Baffled Science Has An Explanation (But Not A Solution)
Back in 2015, we told you about the mysterious hum that made both people and science go bananas -- an inexplicable cosmic mumbling that can occur in places as diverse as Taos and England, driving some to the brink of insanity. For decades, scientists were baffled by the mysterious hum that would erupt spontaneously in places near the shore. Often, they managed to pass the blame onto local nuisances, like submarines or factories, but they couldn't explain why only some people heard it, or why the very same sound would erupt randomly on the other side of the globe years later. And the problem only grew, as some reported that the hum was causing headaches, nosebleeds, and in one instance even drove someone to suicide.
But science never sleeps -- especially not when the cosmos is humming in an annoying way. So after years of research and theories, scientists at the Centre National de la Recherche Scientifique in France finally found the culprit for this mysterious phenomenon: hardcore wet grinding. Specifically, long ocean waves putting so much pressure on the seabed that the Earth oscillates. That continuous vibration can cause minor seismic humming that can last up five minutes. Unfortunately, we'll probably never figure out a way to get the Earth to shut up. Fortunately, most of us are pretty lucky that we'll never hear it. But pity the small portion of the population who will forever be cursed by Poseidon's late-night grind sessions.
