如果你看过电影“2012”或“世界末日”或者读到“在海滩上”,你就会知道一些可能终结生命的威胁。太阳可以做些令人讨厌的事情。流星可能会袭来。我们可以将自己从存在中解脱出来。这些只是一些众所周知的灭绝级事件。还有很多方法可以死!但首先,灭绝事件到底是什么?灭绝等级事件或ELE是一场灾难,导致地球上大多数物种灭绝。这不是每天发生的物种的正常灭绝。它不一定是所有生物体的绝育。我们可以通过检查岩石的沉积和化学成分,化石记录以及卫星和其他行星上的重大事件的证据来识别主要的灭绝事件。有许多现象能够导致大范围的灭绝,但它们可以分为几类:生命就像我们所知道的那样,没有太阳就不存在,但说实话。太阳把它用于地球。即使这个名单上的其他灾难都没有发生,太阳也将结束我们。像太阳一样的恒星随着时间的推移燃烧得更亮,因为它们将氢融合成氦气。在另一个十亿年中,它将大约亮10%。虽然这看起来似乎并不重要,但会导致更多的水蒸发。水是温室气体,因此它会在大气中捕获热量,导致更多的蒸发。阳光会将水分解为氢气和氧气,因此它可以流入太空。如果任何生命存活下来,当太阳进入红巨星阶段时,它会遇到火热的命运,扩展到火星轨道。在太阳内部生存的可能性不大。

澳大利亚墨尔本大学天文学论文代写:终结生命的威胁

If you’ve seen the movie “2012” or “the end of the world” or read “on the beach,” you’ll know some threats that might end your life. The sun can do something annoying. Meteors may hit. We can free ourselves from being. These are just some of the well-known extinction events. There are still many ways to die! But first, what exactly is the extinction event? The extinction level event or ELE is a disaster that causes most species on the planet to become extinct. This is not the normal extinction of the species that occurs every day. It is not necessarily the sterilization of all organisms. We can identify major extinction events by examining rock sediments and chemical composition, fossil records, and evidence of major events on satellites and other planets. There are many phenomena that can lead to a wide range of extinctions, but they can be divided into several categories: life is as we know, no sun does not exist, but to be honest. The sun uses it for the earth. Even if other disasters on this list have not happened, the sun will end us. Stars like the sun burn brighter over time as they fuse hydrogen into helium. In another billion years, it will be about 10% brighter. Although this does not seem to matter, it will cause more water to evaporate. Water is a greenhouse gas, so it captures heat in the atmosphere, causing more evaporation. Sunlight breaks down water into hydrogen and oxygen, so it can flow into space. If any life survives, when the sun enters the red giant stage, it will encounter a fiery fate that extends to Mars orbit. It is unlikely to survive inside the sun.
