Earth has a new man-made protective 'force field'

[Swordsmyth]

Earth might seem like a cozy place to live, and that's mostly true, but only due to a very thin protective barrier generated by our planet's magnetic field. Without this natural shield, we'd be under constant assault by extreme space weather like coronal mass ejections.
But now scientists believe we may have another way to protect ourselves should our natural shield break down, an artificial force field-like boundary that we accidentally, inadvertently, created, reports Newsweek.
It turns out that our communications using very low frequency radio signals, such when radio telescopes are transmitted from the ground and are used to communicate with submarines, have been leaking out into space and interacting with electrons and ions there. This interaction has resulted in a sort of VFL (Very Low Frequency) "bubble" that completely enshrouds our planet.
“A number of experiments and observations have figured out that, under the right conditions, radio communications signals in the VLF frequency range can in fact affect the properties of the high-energy radiation environment around the Earth,” Phil Erickson, one of the scientists involved, said in a statement.

sounds very interesting.
