Here it is again. Scentifica a discovery that is confirming the philosophical and spiritual. The research is reported in the journal Nature. (Http://www.nature.com/nature/journal/v515/n7528/full/nature13956.html)
The Earth is wrapped in an invisible force field that scientists have likened to the shields of Star Trek. An American team has discovered a barrier, about 7,200 miles above the Earth's surface, which blocks the high-energy electrons that threaten astronauts and satellites.
Scientists have identified a border "extremely sharp" within the Van Allen belts, two large ring-shaped donut kept them from the Earth's magnetic field, which are full of fast moving particles. Lead researcher Professor Daniel Baker, from the University of Colorado at Boulder, said: "It 's almost as if they were running these electrons on a glass wall in the space.
"As the shields created by the force fields of Star Trek, which were used to repel the alien weapons, we are seeing an invisible shield that blocks these electrons. It is a phenomenon extremely enigmatic. "
The team initially thought the high electron charge, forming a ring around the Earth at over 100,000 kilometers per second, would slowly drifted to the upper atmosphere. But a pair of probes launched in 2012 to study the Van Allen belts, showed that the electrons are stopped on their way before you get that far.
The nature of the force field remains an unsolved mystery. It does not seem to be connected to the magnetic field lines or radio signals artificial and scientists are not convinced that a cloud of electrically charged gas called cold plasmasphere, which stretches for thousands of kilometers in the outer Van Allen belt, is able to explain fully the phenomenon.
Prof Baker added: "I think the key here is to continue to observe the region in detail, something that we can do thanks to the powerful tools in the probes Van Allen."
