A huge rock hurtles through the empty void of space. Its been orbiting the sun for hundreds of millions of years. But this orbit will be different. This time its trajectory and the orbit of earth intersect. It will impact somewhere in southern Ohio releasing energy equivalent to a large thermonuclear weapon and creating a crater five miles across. Alert the governor, start evacuations! But wait, it's already too late!
It's too late because the impact occurred during the Permian Period Read more ➜ Serpent Mound
