According to all known models of stellar fusion mechanics, the End of the World will occur in about 5,000,000,000 years, when the Sun's core runs out of hydrogen as its nuclear fuel. The core will then contract and the outer layers will expand, cool, and become less bright. It will become a red giant star, at which time it will vaporize the inner planets (Mercury, Venus, Earth, and Mars). After this phase, the outer layers of the Sun will continue to expand. As this happens, the core will contract; the helium atoms in the core will fuse together, forming carbon atoms and releasing energy. The core will then be stable since the carbon atoms are not further compressible - it will have become a multi-billion-ton diamond, a fitting cenotaph for the Late, Great Planet Earth.
Before this, I think there would be another ice age in a few hundreds of thousands of years, correct me if I'm wrong. Not that the world will end, but that it would affect humans.
I do have a question (I'm not much into apocaliptic scenarios why I ask), I heard that a solar wind having had to pass the protection of our magnetic field might cause a chaos regarding electricity in a continental scale, is this a myth, is is too exaggerated or is a possibility? (I know an event like this has nothing to do with the December 21st crap but a related topic)
