ब्रह्मांड का पहला अणु जो लगभग 14 बिलियन साल पहले बना था, हाल ही में नासा द्वारा पाया गया __________ है।

  • 1हाइड्रोजन सल्फाइड
  • 2Tributyltin hydride
  • 3हीलियम हाइड्राइड
  • 4बेरिलियम ऑक्साइड
Answer:- 3

Helium hydride ion (HeH+), the first molecule that formed almost 14 billion years ago, was detected by NASA's flying observatory SOFIA towards a planetary nebula. It is the first type of molecule (first molecular bond) that formed in the universe after the Big Bang. At that time, ionised hydrogen and neutral helium atoms reacted to form HeH+. Once the universe cooled down, hydrogen atoms started to interact with helium hydride, creating molecular hydrogen, which set the stage for star formation. From that point on, stars created the other elements of the cosmos.
