Why is it believed that lithium was present along Hydrogen and Helium already at first?
That's really cool. Is there anything else you can tell me about how the universe evolved in the early moments after the Big Bang?
Well, one of the most important events in the evolution of the early universe was the period of cosmic inflation, which occurred just fractions of a second after the Big Bang. This rapid expansion of the universe is thought to have caused the universe to cool down quickly and even out its density, which allowed the formation of structures like galaxies and stars later on.
