The origin of the universe, which dates back 14 billion years, triggered a volatile and unstoppable process
In order to trace the origins of the universe, and understand when and how the Sun, Moon and Earth were formed, we have to go back billions of years.
The most widely accepted theory on the origin of the universe is the Big Bang, which occurred around 14 billion years ago: a violent explosion released a large amount of dust and gas that spread throughout space. Much later, about 4.6 billion years ago, those very hot gases began to stir, giving rise first to the Sun, and then to other planets, including the Earth.
Billions of years after the Big Bang, the Earth came into existence. Despite the events that followed, this process of continuous transformation has never stopped, and continues to change to this day.
