Did hydrogen come from the big bang
WebAsked by: Elliott Farquhar, via email. We’re taught at school that energy can’t be created, merely converted from one form to another. But at the birth of the Universe – that is, … WebThe free neutrons will then beta decay to yield protons (hydrogen nuclei) and electrons. This is a weak reaction, so the protons produced here were not present shortly after the big bang. So not all hydrogen atoms originate from protons made in the big bang, though other sources are negligible, so your calculation looks OK to me. Share Cite

Web380,000 years after the Big Bang - The temperature of the universe had cooled to about 3000 K. Electrons began to combine with hydrogen and helium nuclei. High energy photons from this period rushed outwards. The early universe was so hot, that as it has expanded and cooled, the highly energetic photons from that time have had their wavelengths ...

WebJan 10, 2024 · The Big Bang is thought to have occurred when something kicked off the expansion of a tiny singularity, some 13.8 billion years ago. Light from shortly after the Big Bang is detectable as the cosmic microwave radiation (CMB).

WebMany cosmologists think its origin lies in so-called quantum uncertainty, which is known to allow energy to emerge literally from nowhere. What isn’t clear, however, is why this cosmic energy persisted long enough to drive the Big Bang.
