I love this stuff. The Ort Cloud is the furthest influence of the Sun's gravitational pull on objects. I have read that we are currently "in phase" with the Ort Cloud. The last time we were "in phase" with the Ort Cloud? When the earth was hit in the Gulf of Mexico by an object that led to the death of the dinosaurs and the vast majority of other life on earth.

really interesting thanks for sharing
