| Description | The origin of the universe and nuclear synthesis are discussed in this paper. The concept of the “Big Bang” is introduced in cosmology from observational evidence that the universe is expanding. The language of elementary particle physics is used to describe the evolution of the universe starting at a very small fraction of a second after the "Big Bang”. Various “Eras” are identified during which certain nuclear processes predominate. At a later stage the remarkable nuclear synthesis of carbon takes place, leading to the evolution of other elements. Neutrino measurements are important to validate physical theories in this field and some results of such measurements by the WITS-CSIR Schonland Research Centre are presented. Teorieë i.v.m. die ontstaan van die heelal en kernsintese word in hierdie artikel bespreek. Die kosmologiese konsep van ’n “Oerknal” is gegrond op waarnemings dat die heelal uitdy. Die ewolusie van die heelal word beskryf vanaf ’n baie klein tydjie na die “Oerknal” d.m.v. die begrippe van elementere deeltjie-fisika. Verskeie “Eras”, waartydens bepaalde kernfisiese prosesse oorheers, word geindentifiseer. In ’n latere stadium vind die merkwaardige kernsintese van koolstof plaas, wat op sy beurt lei tot die ewolusie van ander elemente. Om fisiese teoriee in hierdie verband te bevestig is dit belangrik om neutrinometings uit te voer en die resultate van sulke metings deur die WITS-WNNR-Schonland-Navorsingsentrum, word aangebied en bespreek. | |
