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. The theory is that so much dirt and debris was exploded into the atmosphere that sunlight could not reach plants. Without food, 75% of Earth life on land and sea, including the dinosaurs, starved to death. What’s becoming more clear is that this extinction event has been happening about every 26 to 30 million years for at least 260 million years, according to Michael Rampino, Ph.D., Professor of Geology at New York University; and his colleague Ken Caldeira, Ph.D., an atmospheric scientists at the Carnegie Institution for Science. In the September 2015 Monthly Notices of the Royal Astronomical Society, the two scientists showed new data about how the rate of craters on Earth have changed over time, specifically showing a cycle of impact craters that occur around the same time as mass extinction events. The scientists’s hypothesis is that cycle hitting around every 26 to 30 million years is linked to the up and down motion of our Sun and solar system through the mid-plane of our Milky Way galaxy. That’s the densest part of our galaxy, filled with more matter and gravitational pull, so that when our sun and planets moves along that mid-plane axis, there will be gravitational perturbations all the way into the Kuiper Belt and Oort cloud of comets that surround our solar system. When that happens, comets get shaken into new orbits headed toward the inner solar system and increased chances of smashing into the planets, including Earth.
