The most probable means by which the world can be expected to end, or to at least become uninhabitable to people, would be as a result of a large comet crashing into the Earth (similar to an event thought to have caused the extinction of the dinosaurs 65 million years ago). If this does not happen, in about 3 billion years the sun will expand into a red giant and the Earth will be cooked.

Scientists pretty much know how the actual planet we live on will end and so their end of the world predictions are likely to be accurate. Even in the few centuries that mankind has studied the universe, the science of astronomy has repeatedly shown that eventually the Sun will expand and consume the first three planets of this solar system. Even if it stops short of the Earth the intense heat will destroy every living thing on this little blue world. The good news is that this won't (or shouldn't) happen for another several billion years. In geological time humans haven't even been on this planet for a single second in the 24 hour lifespan of the Earth.

However, the bad news is there are many ways in which the planet could change so radically that the vast majority of people would be unable to survive. There are even some events that could end all life long before our several billion year window closes. According to many respected scientists - some of these predictions will definitely occur it's just a matter of when. In short, the only way that humanity will survive in the very long-term is get off this planet and spread across the universe (a bit like a virus moving from cell-to-cell). This page examines the predictions for the way in which humanity (and on occasions the whole world) is likely to end. We've ranked these predictions in order of diminishing likelihood. We reserve the right to change the order as and when we feel like it.
