01.All it started with a Big Bang - a massive explosion that lasts for less than one trillionth of a second that will create tiny particles of radiation smaller than the size of a full stop.
02.After 380,000 years the first atom was formed with 74% hydrogen and 24% helium.
03.After 1 billion years the first stars were formed, and there were dwarf galaxies throughout the Universe.
04.When the Universe was 3 billion years old, small galaxies were merged to form massive ones.
05.When 9 million years old, our Solar System was formed in the Milky Way Galaxy.
