Answer to Question 1

Radiation originally filled the entire universe. There was sufficient energy for photons to transform into stable protons and neutrons. As temperatures dropped, electrons and positrons were formed next. Meanwhile, the protons and neutrons fused to make deuterium, and deuterium fusion led to helium production in the first few minutes. As the temperature fell still more, this production ceased, and finally at decoupling, electrons began to orbit the protons to form neutral hydrogen atoms.
