The sun will die. The scientists in the UK predict that the sun will turn into a "red giant" and its center will shrink in about 5 billion years from now. Its outer layers will expand as far as Mars. This means Earth will be burnt and disappear, which means there will be no humans on Earth when the Sun dies out.
