What is the hypothesis of rare soil?

The

hypothesis of rare soil claims that Earth is rare and that few planets can support a complex life. The hypothesis of rare soils stands, unlike the principle of averageness, which assumes that Earth must be a typical planet, because there should be nothing special about humanity or earth. Numerous arguments for rare soil hypothesis were submitted to explain why the country is unique; Some analyzes suggest that Earth is the only planet capable of promoting a complex life in the milk path, or even the entire visible universe. Abiogenesis, creating life, requires that the broth react to organic chemicals, which in turn requires a large water formation. It is not known that no other planet than Earth has liquid water in significant quantities and few planets have the right temperature to remain liquid; If the planet is too hot, the water is cooked into space and cold planets keep all their water frozen.

The development of complex life also requires the planet to be protected from risks such as cosmic radiation, extreme weather conditions and the impact of asteroids. According to the hypothesis of rare soil, the country can be unusually happy in this respect. The outer planet Jupiter has a sufficiently strong gravitational field that bends the roads of the comet to the inner solar system and the Earth. The unusually large size of the moon allows the Earth axis to stabilize, maintain stable climate formulas, and the Earth geology gives it a strong magnetic field, and helps to divert high energy protons and other charged cosmic radiation. It is unlikely that any random planet, even if it has liquid water, should all shields in place to avoid extinction events.

The

hypothesis of rare soil remains controversyial, and many scientists have pointed out that Earth type environment may not be the only one that can support life. Although the development of complex life is rare, the galaxy of the Milky Way itself contains more than one hundred billion stars,Which provides many chances for life to evolve. Future space missions, which are designed to directly observe extrasolar planets, could help solve some of these questions by measuring the habitation of a large number of planets orbiting stars near the Sun.
