Question

Dear sir or madam ,

My most hard doubt question is :-

How gasses in the universe are formed at first , for example hydrogen , nitrogen, etc, .

Answer 1

Researchers believe that our universe began with the Big Bang about 13 billion years ago, and that soon after that event, matter began to form as small dust grains and gases. The chemistry of the cosmos today is not what it used to be. The stars and planets and interstellar gas around us are laced with carbon, oxygen, and many other elements heavier than hydrogen and helium—the only substances to have existed for a few hundred million years after the big bang. Until recently, nobody had seen any of that primordial gas from those early days of cosmic history
