The Most Terrifying Era on Earth — A Time When Survival Was Nearly Impossible

The Most Terrifying Era on Earth — A Time When Survival Was Nearly Impossible ► Subscribe: https://goo.gl/r5jd1F This is our planet. And no, this isn’t some mistake. What you’re looking at really is Earth, except you’re seeing it the way it was 466 million years ago. There is a giant ring system that orbits it, similar to the one that currently surrounds Saturn. Billions of rocky fragments slowly circle the planet, forming a shimmering band in the sky. According to one hypothesis, these rings could have existed for tens of millions of years. And their emergence may have triggered a chain of extremely destructive events. They cast a shadow over the Earth's surface, affecting the planet's climate. Temperatures dropped, glaciers advanced, ecosystems began to collapse. And the planet shook from powerful surface impacts. Some scientists believe that this was when the first of the five largest mass extinctions occurred. But how could Earth have developed rings at all? What was happening on the surface when this massive rock ring loomed overhead? And what would it be like to find yourself at each time when nearly all life on Earth was almost wiped out?
