Detailed explanation-1: -In the beginning, or at least following the Big Bang more than 14 billion years ago, there was hydrogen, some helium and a little bit of lithium. A grand total of three elements. Today, there are nearly 100 known naturally occurring elements, with hundreds of variants.
Detailed explanation-2: -Cosmologists believe a process called inflation happened in the fraction of a second after the Big Bang. There was a strange type of vacuum energy that caused the universe-the volume of space itself-to expand by a factor of 10^78 in a fraction of a second.
Detailed explanation-3: -Protons and neutrons began forming shortly after, from about 10-6 to 1 second after the Big Bang. Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei. This is called the era of nucleosynthesis.
