RE: Schumann frequency - Houston, we have a problem!
Posted by pictureguy on April 27, 2015 at 11:45:31:
I don't care about 'who is more accurate'. big Deal on Acoustic revive vs 'other'.
Based on a recognized value for Earth's Circumference = 24901 miles, the resonant frequency should be about 7.841hz, not the 7.83 oft quoted. The difference is greater than 1/10 of 1% and is well within measurement accuracy. Maybe around .14%? Also, Since the Earth is not a perfect sphere, THAT may introduce some 'wiggle' to the measurement.
And yes, Geof, Earth does indeed get larger over time. The simple accretion of Meteor 'stuff' assures THAT. Not much, but over several Billion years, it DOES add up. I don't know how it plays into the Schumann Resonance, but Earth's electrical activity has varied a quite a bit over long time periods, as well.
And just for shits 'n giggles? WHO measured the Schumann Resonance in times past? Grog the Caveman? Cheops? Eratosthenes? Hemiunu?
You are making an assumption on tenuous grounds.
