The mass of the earth.

According to the latest astronomical calculations, the mass of the Earth is equal to 5,97 × 1 024 kg.Annual measurement of this magnitude clearly demonstrate that it is not absolutely constant.Its data range up to 50 thousand tons per year.Earth is the largest largest diameter, mass and density among the planets belonging to the terrestrial.Within the solar system, our planet third from the Sun and the fifth in size among all the others.It moves in an elliptical orbit around the Sun at an average distance from him 149,600,000 kilometers.

Since the mass of the Earth is changing, there are a large number of opinions on the trends of the changes.On the one hand, this value is constantly increasing due to collisions with meteorites that burn up in the atmosphere left a large amount of dust is deposited on the planet.On the other hand, the ultraviolet solar radiation constantly splits water molecules in the upper atmosphere, to oxygen and hydrogen.Part of the hydrogen due to its light weight is pulled out from the gravitational field of the planet, which affects its weight.

Since the beginning of the 19th century to the last decades of the 20th century theory of the expanding Earth has been very popular among scientists around the world.The hypothesis of an increase in the world has caused the assumption that the mass of the Earth is also increasing.During the entire existence of this theory was proposed by different scientists five options for its justification.Many well-known scholars such as Kropotkin, Milanovsky, Steiner and Schneider, argued the expansion of the world of its cyclical fluctuations.Dakill Myers, Clube and Napier explained this assumption is the constant adherence to the Earth asteroids and meteorites.The most popular theory of the expansion was the assumption that the original core of our planet consisted of superdense matter, which in the process of evolution turned into a normal material, causing a gradual increase of the Earth.In the last 50 years of the last century, several eminent physicists such as Dirac, Jordan, Dicke, Ivanenko and Saggitov, expressed the view that the gravity value decreases with time, and this leads to a natural extension of the planet.Another hypothesis was the opinion Kirillov Neumann Blinov and Veselova that the cosmological expansion of the Earth caused by reasons related to the age-old evolutionary increase in its mass.Today, a large amount of evidence to refute these assumptions.

theory of the expanding of the planet, based on the fact that the mass of the Earth is constantly growing, now completely lost its appeal.An international team, composed of the best scientists of the world, finally confirmed it, so today this concept can peacefully go on the shelf of scientific archives.

According to the group of geophysicists conduct research using modern space vehicles, the mass of the planet Earth is relatively constant.An employee of one of the research laboratories W. Xiaoping and his colleagues published an article in which he said that the radius of the Earth recorded fluctuations do not exceed 0.1 mm (the thickness of a human hair) in a year.These statistics suggest that the mass of the Earth does not change in values, lets talk about its expansion.
