Abstract

Cilj diplomskog rada jest proučiti osnovne koncepte teorije Velikog praska te razmotriti što se događalo tijekom prve tri minute nastajanja svemira. Prikazat ćemo glavna dva dokaza koji su zaslužni što je teorija Velikog praska danas najviše zastupljena te pojedine miskoncepcije koje se javljaju prilikom istih. Dokazi koji idu u prilog teoriji Velikog praska su opažanje da se svemir širi i otkriće pozadinskog mikrovalnog kozmičkog zračenja. Kroz upoznavanje fundamentalnih čestica i fundamentalnih sila radimo uvod u detaljnije razmatranje same fizike ranog svemira te na koji način su se čestice ponašale. U zasebnom poglavlju je pojašnjeno razdoblje nukleosinteze i prikazano dobivanje omjera broja pojedinih čestica tijekom tog razdoblja. Kroz metodički dio samog rada cilj nam je približiti nastanak svemira učenicima kroz seminarski rad provodeći interaktivnu nastavu. Ponavljajući gradivo koje su učenici usvojili tijekom 3. i 4. razreda srednje škole, možemo učenike upoznati s osnovnim konceptima teorije Velikog praska. Navođenjem učenika postavljamo temelje za širenje svemira i pojašnjavamo važnost pozadinskog zračenja. Na kraju sata predviđeno je gledanje kratkog filma, tj. simulacije sudaranja čestica u trenutno najvećem akceleratoru čestica, CERN-u.

Abstract (english)

The aim diploma thesis is to study the basic concepts of the theory of the Big Bang, and consider what happened during the first three minutes of the universe formation. We will show two main evidences for the Big Bang, and explain some misunderstandings that occur with Big Bang concepts. Evidence in favor of the Big Bang theory are, observation that the universe is expanding and the discovery of the cosmic microwave background radiation. Through the introduction of fundamental particles and fundamental forces we will be able to give more detailed discussion of the physics of the early universe, and how the particles behave. In a separate chapter we will explained the period of nucleosynthesis and displayed obtain ratios of individual particles during this period. Through the methodological part of the thesis we aim to bring students through the formation of the universe, which will result in preparation for conducting interactive classes. Summarizing material that students have acquired during the third and fourth years of high school, they can be introduced to the basic concepts of the theory of the Big Bang. Using this approach the students will lay the foundation for the expansion of the universe and explaining the importance of background radiation. At the end of the session it is planned to watch a short film, simulations of particle collisions in the currently largest particle accelerator, CERN.
