AI Thread Summary
The Earth does have a frequency, primarily identified through Schumann resonances, which are electromagnetic waves in the Earth's ionosphere. These resonances occur due to lightning-induced currents and create a waveguide between the ground and the ionosphere. The fundamental frequency is approximately 7.83 Hz, with additional peaks at 14.3, 20.8, 27.3, and 33.8 Hz. Additionally, tectonic activity and earthquakes contribute to the Earth's vibrational characteristics. Understanding these frequencies provides insights into the Earth's structure and behavior.

This is probably a dumb question but I was wondering if the Earth had a frequency. I would think with such a massive object there would be a certain background vibration from tectonic plates moving around.

Yes - and the vibrations from earthquakes and such tell us about the structure of the earth
 
cool. Does it vibrate at a certain frequency or is it just random?

That's a great link, Mr. Special. I don't currently have time to peruse it, but will in the near future.
 
The first part to your question "I was wondering if the Earth had a frequency" can also be answered from an electromagnetic standpoint. Schumann resonances are frequencies in the EM field of the earth. Essentially, the ground the ionosphere create a waveguide and is excited by current induced from lighting. The peaks are at 7.83, 14.3, 20.8, 27.3 and 33.8 Hz.

Thread 'Is there a white hole inside every black hole?'

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Is Gravity an entropic property like Surface Tension'

Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
