| THE BIG BANG | ||||||||||||||||||||||
| It's All In the Elements Baby! | ||||||||||||||||||||||
| That's Hot! | ||||||||||||||||||||||
| The universe was very hot dense and very dense. When the expansion began the universe began to rapidly cool (now you need to understand how truly hot it really was; aproximitly one minute after the initial push that set off the expansion it was about 3000 billion degrees Kelvin). For up to a 10^-10 seconds after the initial push there wasn't really anything but quarks, quarks are the fundamental particles (that's what makes up protons, electrons, ect). It is thought that for a couple of seconds there was just some ionized goo, because it was too hot for the quarks to form anything. | ||||||||||||||||||||||
| Fusion Fun | ||||||||||||||||||||||
 |
||||||||||||||||||||||
| Then after about 10^-5 seconds or so leptons started to form. Some leptons are electrons, neutrinos and photons. These leptons began to fuse with one another in about 3 mins. (boy do they work fast). Fusion is when multiple nuclei join to together by the release or absorption of energy. Normally if the two nuclei are heavier than nickel or iron than the tend to release energy and if they are lighter than they tend to absorb energy. This fusion started to make light elements, but the first element (from what can be told) is Deuterium, this is a heavier form of hydrogen. Then it collected another neutron to form Tritium. Soon after Helium was created with the addition of one proton. With in the first three minutes there was one helium nucleus for every ten protons. With in the first couple of minutes all of the elements with an atomic number less than and including Iron (55.85 amu) had been created. |
