Exactly three years ago, NASA space probes discovered strange phenomena in space. They resemble an artificial barrier that completely surrounds our planet. The beginning of research on this amazing barrier showed that it somehow affects space weather outside the atmosphere of our planet. The scientists suggest that it is due to the vigorous activity of people. They call for the name of a new geological era in honor of humanity, since the inhabitant of the Earth really changed space.
The good news is that unlike the impact on the planet itself, the artificially created barrier works in favor of earthlings. In 2012, NASA sent two probes into space, they worked together, their speed was about 3.2 thousand kilometers per hour.
Three years ago, probes discovered something strange while observing the activity of charged particles that were attracted by the Earth's magnetic field. All dangerous solar discharges were strangely contained by an incomprehensible low-frequency barrier. The researchers began to study that fact and found that the barrier has been actively pushing the Van Allen belt away from the Earth over the past several decades.
And as a result, the lower limits of radiation fluxes are much farther than, for example, they were located in the 60s of the last century. Then there was a certain type of transmission, radio communication with a low frequency.
Over time, it became very common and now NASA has evidence that it can affect the movement of individual particles in outer space. That is, due to these waves with a low frequency, and they were created by human hands, anthropogenic space weather appeared. Several experiments and observations helped to explain that, under certain conditions, radio communication signals can influence the properties of the high-energy radiation environment around our planet.
So says Phil Erickson of the Haystack Observatory at the Massachusetts Institute of Technology. And although people constantly have nothing to do with these signals, they are the basis of engineering, scientific, military operations.
Frequencies from 3 to 30 kilohertz are considered weak for transmitting audio information. But they are perfect for transmitting encrypted messages over long distances or underwater. The most common mechanism for such transmission is communication with submarines. Long wavelengths can be scattered around obstacles such as mountain ranges, and that technique is used to transmit signals across difficult terrain.
These signals were not intended anywhere but the Earth. But they are able to seep into space and surround our planet, lingering long enough to form a giant protective bubble. By comparing its boundaries with the boundaries of the radiation belts, the astronomers found surprising coincidences.
The charged particles in the radiation belts found themselves in an artificial barrier, which gradually repelled them. The scientists believe the barrier is insurmountable. Of course, it is another trail that a person leaves in space after a series of nuclear explosions.
