AS102 Study Guide - Midterm Guide: Beryllium
Document Summary
Since then other, more sophisticated measurements of the cmb have been made resulting in the picture shown below which shows the slight temperature differences (no bigger than 0. 0001 k) which created a slightly. lumpy distribution of matter at the end of the era of nuclei which resulted in the stars and galaxies of today. Another important piece of evidence supporting the big bang theory came from measurements of the types and quantities of elements in the universe. You will recall from the last lesson that the theory predicted that within the first few minutes following the big bang one electron combined with one proton to make hydrogen. The temperature was high enough for hydrogen fusion to take place, forming helium. Additionally, very small amounts of lithium and possibly beryllium were made but that s it - the temperature was dropping too rapidly.
