The loss of the magnetic field of the Earth. Prospects and the risk to human

On our planet, now there are processes, which may be a significant threat to all life on Earth, as well as lead to its complete disappearance. One of these processes may be the loss of Earth's magnetic field, and the current data suggest that the likelihood of such a development as the years increase. Change of poles is underway. Where will this lead? As you know, our planet's magnetic poles is caused by features of a solid and a liquid core of the Earth. Their interaction is based on the principle of the core around which is laid turns of copper wire. The impact of facilities Read more [...]

In 2012, may be a change of the magnetic poles of the earth

German scientists found that the Earth's magnetic field is developed with incredibly fast since modern humans first mastered Europe, reversing the poles of its less than a thousand years, news agencies reported, with reference to the German Research Centre for Geosciences. Previously it was thought that the Earth's magnetic poles switch places every few hundred thousand years. However, German scientists have refuted this theory. According to an expert on paleomagnetism of the German Research Centre of Geosciences Norbert Novatsuk, now the magnetic poles change places only 41 thousand Read more [...]

Traces of the magnetic field of galactic dimensions

Two years ago, scientists at the Harvard-Smithsonian Center for Astrophysics (USA) announced the discovery of two giant twin lobes formed by gamma radiation, to retire on 50 thousand light-years above and below the plane of the Milky Way. It seemed that these bubbles came from the field of the supermassive black hole Sagittarius A * at the galactic core. There is even a theory that the "gamma-petals" are generated by emission from the vicinity of SMCHD Sagittarius A *. The alternative hypothesis, put forward at the same time, it is assumed that the reason for their occurrence, by contrast, Read more [...]

Super-Earths could have a strong magnetic field

Although the core of the "super-Earths" due to excessive pressure is not able to operate the magnetic dynamo, like Earth's magnetic field are still possible: it turns out, magnesium oxide, a hard ground conditions, in their robes must be liquid.Many astronomers believe most of the "super-Earths" lifeless, because they do not have the most important components of the magnetic dynamo, which generates a magnetic field (which protects, for example, the Earth). The reason, presumably, is too much pressure in the core, for it excludes the hydrodynamic behavior, as well as effective Read more [...]

The electromagnetic field of the earth is weakening

The core of our planet is inextricably linked with the magnetic field of the Earth. In XVII century, it was observed that the dipole magnetic field of the planet is substantially changed. The geomagnetic field has a fixed component - the dipole field (its contribution 99%) and variable (1%). Main magnetic field configuration is almost the same round of the current (dipole), which is offset from the center of the earth, and the axis is inclined to the axis of rotation of 11.5 degrees. The average field strength - 0.56 Oe. The magnetic field extends to 20-25 Earth radii and forms a kind of protective Read more [...]

Unknown processes in the Earth's core

There is the assumption that the source of heat is the world's natural nuclear reactor in uranium several kilometers in diameter in the center of the world [Anisichkin 1998]. Under certain conditions, suggests B. Anisichkin, for example, in a collision with a large comet, he can go into a supercritical state and cause the explosion of the planet, which, perhaps, was the reason for the explosion of Phaeton, from which may have formed part of the asteroid belt. Theory is obviously debatable, since the very existence of the Phaeton is not proved, and on the contrary, it is believed that the Read more [...]

Reversal of the Earth's magnetic field

We live in period weakening and likely subsequent reversal of the magnetic field of the Earth. By itself, the inversion of the magnetic field does not lead to the extinction of people, because reversal has occurred many times in the past without any noticeable damage. In the middle of a reversal in the magnetic field may soon drop to zero or pole can be oriented to the sun, when will the equator, leading to intense charged particles sucked into the Earth's atmosphere1. However, the simultaneous combination of three factors - the drop to zero of the magnetic field of the earth, ozone depletion Read more [...]
