What was the universe like during its early history? Described were the sequence of events that cosmologists believe unfolded during the first quarter of a million years of the universes's expansion: the lightest chemical elements were formed, the imbalance between matter and antimatter was established, and the small irregularities that eventually formed galaxies were seeded and began to grow. The first few minutes of the universe's history leave traces that we can detect today.
