Yes, it is fascinating stuff. There is some evidence to support it. Astronomers speculate that there is a tenth planet, one with an eccentric orbit. Some think that every 65 million years it swings close enough to the Oort cloud to dislodge the asteroids and comets that circle way out beyond Pluto, dislodging some and sending them Earthwards. This might explain why there are major extinctions here.
