Science - Asteroid Strike



Geological findings prove that the impact of a large asteroid brought about the obliteration of up to 70% of all life on Earth 65 million years ago. Asteroid Strike traces each step of this catastrophic event, and shows how this planets last occurrence of mass extinction led to the birth and evolution of the human species. The formation of this theory came to be during an investigation into what caused the extinction of the dinosaurs, an event that has obsessed researchers for many decades. Thirty years ago, paleontologist Jan Smit made unearthed one of the most startling pieces of evidence in support of this theory while trekking among the rolling cliffs of northern Spain. Through careful chemical analysis of rock samples, Smit detected large quantities of iridium, an extremely rare element most commonly found in meteorites and asteroids. This revelation provided the breakthrough scientists had been searching for, and the hunt was on for the site where the asteroids landing may have originated and evidence of the events that transpired in the aftermath of its impact. As documented in Asteroid Strike, what follows plays like the ultimate detective story, as the filmmakers join a team of scientists on a journey of discovery across the globe from the mountain ranges of Colorado to the glorious natural environment of the Yucatan Peninsula. In retracing this global catastrophe, they make us frighteningly aware of our planets vulnerabilities among the scope of an infinitely larger universe, and how our very existence was brought about by mere happenstance. Hyper-realistic animations allow us to experience the asteroids impact on a visceral level as waves of fire engulf all life in their path over thousands of miles. The resulting mass-scale tsunamis further decimated Earths landscape. Following impact, the planet underwent severe episodes of climate change that would last for hundreds of years. It literally would have been Hell on Earth, observes Dr. Dan Durda, a planetary scientist and one of the films interview subjects. In the midst of such devastation, life found a way to rebound. Therein lies the most fascinating and mind-boggling aspect of this film. As summarized by the narrator Tony Robinson, Its extraordinary that we may owe our very existence to one freak event.
