Collision course

This is something that, in the right frame of mind, and with enough edibles, can really keep you up at night! We are constantly on a collission course with millions of flying rocks as we hurtle through infinity at hundreds of thousands of miles per hr....

We are tiny creatures living on a bigger rock spinning aroubd a star at 67000 MPH. On top of that the entire solar system is travelling at 490,000 MPH. Dizzy yet??

Our galaxy is part if a group of galaxies travelling toward a black hole that is 100 QUADRILLION times larger than our black hole, at 2.24 million MPH! And you think your Corvette is fast....
