Gravitational Waves

If you are left bemused by the scale and forces of the universe, the size of the events that caused the gravitational waves discovered recently is almost beyond imagination. Lawrence Kraus, who is a theoretical physicist and the author of The Science of Star Trek, describes here both the genesis of these gravitational waves and, as extraordinary, the human skill and ingenuity involved in measuring them. 

If I get any choice in my reincarnation I want to come back as an astrophysicist.
