Moddaning paydo bo‘lishi.
Koinot rivojlanishining radiatsion erasi juda muxim xioblanadi. Aynan shu davrda D. Mendeleev davriy sistemasini tashkil qiluvchi elementlarning asosi – og‘ir yadrolar paydo bo‘la boshlangan. Ushbu jarayon nukleosintez deb nomlanadi. Eng engil yadro – proton Koinot paydo boshlgandan 10 sekund o‘tib paydo bo‘lgan. Ushbu davrda Koinotning temperaturasi va zichligi deyteriy – ikkita nuklondan tashkil topgan yadroni sintezi uchun etarli katta bo‘lib, proton va neytronning to‘qnashishi natijasida paydo bo‘lgan.
p + n ²H + + Q.
Bu erda Q = 2.2 MeV – ushbu sintez reaksiyasida ajralib chiqadigan energiya. Keyin 10-15 minut vaqt ichida ²H deyteriyni ³H tritiyga aylanishi, so‘ngra deyteriy va tritiydan ³He geliy yadrosining paydo bo‘lish reaksiyalari sodir bo‘lgan^¹³. Hisob natijalariga ko‘ra geliy barcha nuklonlar ichida 24 foizni tashkil qilgan. Xozirgi paytdagi kuzatuv natijalari ham shuni ta’kidlamoqda.
