Why is the sun such a hot-spot? How has it been able to achieve such a temperature imbalance, and thereby provide a state of low entropy? The answer is that it has formed by gravitational contraction from a previously uniform distribution of gas (mainly hydrogen). As it contracted, in the early stages of its formation, the sun heated up. It would have continued to contract and to heat up even further except that, when its temperature and pressure reached a certain point, it found another source of energy, besides that of gravitational contraction,
