A 26-million-year-cyclical pattern has been linked to periodic motion
of our solar system through the dense mid-plane of the Milky Way galaxy.
“The correlation between the formation of these impacts and extinction
events over the past 260 million years is striking and suggests
a cause-and-effect relationship.”

November 20, 2015 New York City, NY - 99% of all the species on Earth that have ever lived are now extinct. Earth's history has been marked by periodic mass extinctions of this planet's evolving life forms. The dinosaurs thrived for about 135 million years until a 6-mile-diameter asteroid slammed into the Gulf of Mexico 66 million years ago leaving the 12-mile-deep and 112-mile-wide Chicxulub crater.
