The important cycle is one approximately 35,000,000 years not 26,000 years. This is the timeit takes for our solar system to make a pass above (or below ) the galactic equator. When the solar system (and earth) cross the galactic equator we move through the flattened gravitational field of the Super Massive Black Hole at the center of our galaxy. THis SMBH was discovered recently and has a mass and spin rate so enormous that its gravity field collapses into a pancake thin layer at the galactic
