its true. well not really. but its AMAZING.
they located the hum of the earth!
its too low for human ears, 10 millihertz.
but it's detectable by seismometers. wouldnt it be lovely to have a seismometer?
so the hum is in fact a reflection of certain waves all along the ocean floor.
allarently, "the hum is caused by the combination of two waves of the same frequency travelling in opposite directions. The waves alternately cancel out and amplify each other so that the sea surface goes from wavy to flat to wavy. This creates a standing wave that "goes thump, thump, thump on the ocean floor at twice the frequency of the waves you started off with, driving the hum", says Webb."
also the hum is strongest on the coast of vancouver. which makes me feel special for some reason. also echart tolle lives in vancouver. i just learned that.
i shoudl mention that this is all from New Scientist.
