- In 1 billion years or less all oceans on earth will be vaporized, Earth's atmosphere will be similar to that of Venus. (according to our current understanding of the evolution of solar-like stars and terrestrial planets) It is hard to imagine life on Earth existing beyond that point. The last remnants of life will probably be residing in the last remnants of the ocean before they are wiped out. Some bacteria could survive in the atmosphere. - A little bit more controversial: the CO2 levels might decrease over the next 500 million years so that photosynthesis becomes inefficient. Land-based plants using the C3 carbon fixation would be the first to become extinct, those using the more efficient C4 carbon fixation would last a little bit longer (e.g. sugar cane). This would be the end of the flora and fauna as we know it, but life goes on  - As for the final fate of the earth I am not quite sure, I would have to read up on it, as it depends on a few variables. The Sun will lose quite some mass before becoming a red giant, which causes Earth's orbit to expand. this might be enough for Earth to escape the Sun's atmosphere (well, not entirely, but enough so that the drag forces do not cause it to spiral in and get destroyed). In that case, Earth (which is unrecognizable after it crashed with the moon) will end as a lifeless rock orbiting a similar sized white dwarf, the remnant core of the Sun. This WD will slowly cool until it finally fades, but that will take many many billion years. edit: I see some people actually went through the trouble and computed Earth's future according to our current understanding: Link to the article It seems like Earth will not escape Sun's grip and thus be swallowed whole, although it is a close call. No lifeless, rocky future  | ||

The sun is a boiling hot meat ball. God is eating spaghetti bolognesé. The only reason he hasn't eaten our sun yet, is because he hasn't gotten around to it, and theres a lot of other suns that are more succulent and juicy. | ||

We'll change to the point where we become a different species or even possibly diverge into multiple species. | ||

Whether it's a bunch of crazy leaders pushing the wrong button, or a really bad virus, even if the odds aren't that great, maths tell us it will happen eventually. Spreading mankind out would at least make sure some of our civilisation survives, which is why I think spatial exploration is the most important thing for mankind at this point. But we're too busy fighting stupid wars... | ||

If so u could choose yourself what way you want to go. Or we are just pets from aliens, they observe us and laugh all the time about us and our strange theories, also we could end as food for them, wouldn't be that bad, at least we would be useful ^^ | ||

I feel sorry for these people. They never learned how to think critically. It's not their fault are culture hates skeptics. | ||

Or perhaps boiled eggs falling from the sky, resulting in a global cholesterole overdose. | ||
