To organize the events according to the Big Bang theory in chronological order, they should be arranged as follows:
1. **Universe begins expanding** - The Big Bang marks the beginning of the universe, around 13.8 billion years ago, leading to rapid expansion.
2. **Hydrogen atoms form** - As the universe cooled after the Big Bang, particles began to combine, forming hydrogen (and helium) atoms roughly a few minutes after the expansion began.
3. **First stars form** - After about 100 million years, the first stars began to form as gas clouds (mainly hydrogen) collapsed under gravity.
4. **First galaxies form** - Following the formation of the first stars, galaxies began to coalesce and form a few hundred million years after the Big Bang.
So, the correct order is:
1. Universe begins expanding
2. Hydrogen atoms form
3. First stars form
4. First galaxies form
