    About five billion years ago a huge cloud of hydrogen gas, about four light years in diameter, began to collapse inward to its centre of gravity, this caused compassion of the gas, heating the Central area which was now at high pressure. The temperature became high enough to make hydrogen atoms stick, fuse, together, this was the birth of a star, it will continue to provide energy for billions of years before it loses enough of its mass to permit radiation to overcome gravity, at that point the sun will begin to swell into a red giant.
