Big History season 1 episode 12, titled "Deadly Meteors," explores the impact of meteoric collisions on Earth's history. Throughout the episode, viewers are taken on a journey through time to witness the devastating effects of these massive space rocks on the planet and its inhabitants.
The episode begins by taking viewers back to the formation of our solar system and explaining how meteors and other celestial bodies were created. Viewers are shown how some of these objects ended up on a collision course with our planet, ultimately resulting in catastrophic events throughout the ages.
One of the first examples of a deadly meteor impact discussed in the episode is the event that led to the extinction of the dinosaurs. Viewers are shown how a large asteroid struck the Earth 66 million years ago, causing a mass extinction event that wiped out the dominant species on the planet. Scientists and researchers are interviewed and share their theories and findings about what exactly happened during this catastrophic event.
Moving forward in time, the episode highlights other instances of deadly meteor impacts throughout history. One such event that is discussed is the Tunguska event of 1908. Here, viewers are shown how a massive explosion occurred in the skies over Siberia, causing hundreds of square miles of forest to be flattened and thousands of animals to be killed. The cause of this explosion is still debated by scientists, but many believe it was the result of a meteor or asteroid that exploded in the atmosphere before reaching the ground.
Later in the episode, viewers are shown how meteor impacts have been the cause of significant changes on Earth. In particular, the impact of the Chicxulub asteroid that wiped out the dinosaurs is said to have altered the planet's climate and geology for millions of years. The episode explains how this impact led to the formation of new continents and mountain ranges, while also changing the chemistry of the Earth's oceans and atmosphere.
Another interesting aspect of this episode is its focus on how meteor impacts have shaped human history. For example, viewers are shown how the impact of a meteor in Egypt may have resulted in the creation of glass, which has been used by humans for thousands of years. Similarly, the episode discusses how meteorite fragments were revered by ancient cultures and were often seen as sacred objects.
Throughout the episode, viewers are also treated to many stunning visual effects and reconstructions. One such sequence shows the potential impact of an asteroid on a major city, highlighting just how devastating such an event would be. Other sequences show what the Earth may have looked like during different periods in history, as well as the formation of the solar system itself.
Overall, Big History season 1 episode 12, "Deadly Meteors," is an engaging and informative look at one of the most awe-inspiring and potentially destructive forces in the universe. Through its exploration of meteors and their impact on Earth's history, the episode highlights the interconnectedness of all things and gives viewers a new perspective on the fragility of our planet.
