Now that the Universe had ____________ ____________ mainly in the form of Hydrogen, which even today still represents 90% of all Energy/Mass/Matter we see, Energy/Mass/Matter could start to clump together to form Stars. ____________ ____________ there would be no abundance of all the Elements we have in ____________ Periodic Table because it is in the burning ____________ of Stars where Radioactive Fusion reactions occur which create all the familiar Atoms such ____________ Oxygen, Chromium, Bromine, Zirconium, Samarium and Selenium. However Stars have to ____________ more massive than our Sun to create the ____________ ____________ as only inside their cores can the temperature and pressure get so high as to cause ____________ Fusion of the lighter Elements. The story doesn't stop there, because once a highly massive Star ____________ turned ____________ its fuel ____________ ____________ it begins to contract and loses energy ____________ a prodigious rate ____________ there is still ____________ final twist in this tale. If other matter crashes into ____________ Iron core the result is ____________ cataclysmic explosion called a SuperNova. This scatters all the Elements which the Star had accumulated and also as the temperature and pressure, again, is higher than ever before in the Star's life, yet more ____________ Elements are created in the tremendous ____________ of the SuperNova. Even unstable Radioactive Elements ____________ as Uranium, Polonium and Francium can be made and are ____________ thrown out into the depths of Space by the continuing explosion.
