I have learned that the formation of the universe started in a 1. ___ and 2. _ (nebula) that collapse into molecular clouds forming the stelar core or also known as 3. _. As it reaches its highest temperature it releases 4. _ and 5. _ increasing the pressure and stops the contraction and once the gravitational equilibrium is reached it will become a 6. _, Big Bang nucleosynthesis is formation of light elements 7. _, 8. _, 9. _, and 10. _, while 11. __, is formation of heavier elements from Boron to Iron. Once, it reached the heaviest element which is 12. through neutron capture where beta decay occurs and 13. _, where atoms collide with one another an explosion of star will occur which is also known as 14. ____.
