Document Summary
George gamow (1904-1968) & ralph alpher (1921-2007) s2 theorized how chemical elements & matter emerged after the big bang termed nucleosynthesis a process of fusion a building up of fundamental particles into basic elements. Predictions for nucleosynthesis were made before scientific instruments were available once these instruments were made observations fit the predictions extremely well. Eg ratios of the light elements (hydrogen, helium, lithium) s3 h40. No energy, no matter, no space, no time absolute & utter nothingness: appearance of energy, space & time s6 this event is termed the big bang . The universe at the big bang is: extremely young. Eg the surface of the sun is 5500 c (5. 5 x 10 )3 extremely small. 0. 00000000000000000000000000000000001 of a metre: at the big bang it is theorized that there is only one force and that out of it emerged the s8 h40 four fundamental forces of nature.
