What kind of environment is more suitable for living on earth? The climate is warm and humid, there is no severe cold in winter, no intense heat in summer, the turtle shell is the least, the air is fresh, and the troubles are visible. The works are surrounded by mountains and waters, and the greening rate is high-definition, close to nature.

From the perspective of stars, what kind of planets are more suitable for life? This planet is in a good position, receiving neither too much nor too little heat from its main star. Star radiation with strong magnetic field or harmful economic particles are protected by gaseous planets against asteroids and comets. But how rough life is, even if this planet is bred by all conditions, it can't escape the danger from the outside world. New research shows that if there is an egg in some areas of the Milky Way in the solar system, a strong cosmic explosion can easily destroy dna.

All possible life near the mold near the speed of light, even a little farther away, may face energy impact. R&D and production talents, such as the Ordovician extinction of the earth, may be caused by gamma ray bursts that occurred within thousands of light years of the earth. In other words, the stable operation of life is also very important.

According to the current theory, from the center of the Milky Way 6500 light-years to our earth's 26000 light-years, this banded region. This is the safest. Explosions near the center of the Milky Way are still common, but there are few terrestrial planets in the outermost part of the Milky Way. Why are the suspect lists equally frequent? Although the earth is safe enough at present, if we are able to settle down in the future, immigrants may really need to look to the center of the galaxy.
