A lot of science fiction films about the extraterrestrial are subject matter with spark, for example classical " spark comes to help " , let people be full of daydream to Martian past, have even quite one part person thinks on spark not only once had wisdom life, and our mankind is likely also with be closely bound up of Martian wisdom life, because Martian environment is exasperate, wisdom life must choose abandon spark to come to the earth. From the point of the macroscopical angle of whole solar system, the earth and spark are located in appropriate to occupy an area, nevertheless the earth nowadays and Martian environment have so big difference, because Martian quality is too small,still be, the protection that did not have magnetic field and aerosphere at the same time (have air, but very rare) . Whether has spark had advanced wisdom life, now basically is to see spark go up to have those who vestigial what build, from eye criminal record observation learning the home looks, martian environment can't come into being the condition that contented life is born, earlier perhaps spark also is mixed the earth is similar, but Martian environment is harsher and harsher later, although life is strong budding, but be strangled very quickly by harsh environment place. Do not eliminate the possibility that wisdom life has appeared on spark of course, after all the environment of every heavenly body is different, the means speed of life evolution evolution will be endless identical the possibility that just says occurrence wisdom life is very little, after all the earth and spark are congeneric solar system, the distance is opposite for it is such close, they should have similar life evolution pattern originally. But detector of a few years of mankinds makes clear to Martian research recently, there is big mark that has been eroded by the river on spark, this shows spark is in distant past is probable also be warm and wet, also ever many seawater exists. In fact, the spark nowadays still has the presence of water, just be to be in polar exist with glacial configuration, this is more affirmative the speculation that spark once had liquid state water! Scientists are conjectural, before billions of years, spark also is common present earth is general vibrant, water of many liquid state exists. Have 11% earthly only as a result of Martian quality nevertheless, what the quantity of heat of in-house iron nucleus cools is very fast, caused spark to lose the protection of magnetic field gradually, the gravitational force plus spark is very small, manacle aerosphere for long in its surface hard, destroy in the abidance of sun wind below, martian aerosphere escapes gradually. And did not have aerosphere protection, martian surface difference in temperature becomes very big, can achieve 100 Celsius above, add those who do not have liquid state water is moist, spark becomes run-down ground, the spark that then we see today became the heavenly body of a deathly stillness. Show according to the research of many sided, spark is the genetic ground of solar system life likely very, it once also had had wet environment, it is later only climate produced major change, if advanced wisdom life is in its wet period came to spark, scatter the seed that left life, change and must leave because of climate again however, so it is likely really by abandon, and the element that those life produce, arrived through aerolite belt again on the earth, enter till the earth wet period, life began major evolution. | | |
