The protective casing however was not formed by an intelligent extra-terrestrial race, but rather evidence that humanity’s impact on Earth extends far beyond the planet itself.
The footprint that modern humans have left on Earth is unprecedented with our rise, especially the industrial revolution and its followthrough, leaving a permanent scar on the planet.
Such has been our impact that experts are calling for a new geological era – the Anthropocene Epoch – to be introduced as we permanently changed the landscape.
However, NASA has revealed that our actions have repercussions far beyond this world.
NASA has discovered a protective bubble around Earth
In 2012, the space agency sent two probes to the Earth’s Van Allen Belts – two radiation belts that surround the Earth.
New data from the probes has revealed that very low frequency, or VLF, radio communications from Earth have been found to interact with particles in space, which has pushed the Van Allen Belts farther out.

Dan Baker, director of the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder, described the new barrier as the “impenetrable barrier” and speculates that if there were no VLF transmissions, the Van Allen Belts would be closer to Earth, exposing us to more radiation from space.
NASA said in a statement: “VLF transmissions may serve as a way to remove excess radiation from the near-Earth environment.”
Solar storms: Sun's solar flares light up space
Tue, April 4, 2017
A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system's largest explosive events. They are seen as bright areas on the sun and last from mere minutes to several hours.

The bubble is protecting us from the likes of solar flares
Phil Erickson, assistant director at the MIT Haystack Observatory, Westford, Massachusetts, said: “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.”
