What eventually became the solar system initially existed as a large, rotating cloud of dust and gas, composed of hydrogen and helium produced in the Big Bang as well as small amounts of heavier elements. Around 4.57 billion years ago, the cloud began to contract, perhaps as a result of a shock wave from a nearby supernova. Inertia caused the rotating cloud to flatten into a disk. Most of the mass concentrated in the middle, and began to heat up. Eventually, the kinetic energy of the hydrogen was sufficient to overcome the electromagnetic repulsion between the protons, and fusion began. The resulting solar wind helped clear away much of the material which had not coalesced into planets or other orbiting bodies.<ref>[http://www.tufts.edu/as/wright_center/cosmic_evolution/docs/text/text_plan_1.html]</ref> The sun is most likely a third-generation star. In Christian theology, [[God]] created the sun on the third day of [[Creation]].<ref>Genesis 1</ref>
