essay pictures hollis woods - 1. Say, “Stellar nucleosynthesis is the term for the nuclear reactions taking place in stars to build the nuclei of the heavier elements. In our sun, the prime energy producer is the fusion of Hydrogen to Helium, occurring at a minimum temperature of 5 million degrees F.” . Nearly all matter is composed of "star stuff". According to the Big Bang theory, the early universe was hot enough to allow the nucleosynthesis of hydrogen, helium, and small amounts of lithium and beryllium. Deuterium, a common isotope of hydrogen, was also important as a reactant in many of the reactions required to form helium. Stellar Nucleosynthesis This would be the end of the story, except that the rapidly expanding universe had a built in brake – gravity, the great sculptor – which operated both globally and locally. The implications of gravity for the entire universe are still the subject of debate, but local effects are better understood. thesis statement game
