I'm a structural engineer in Mississippi and I love all aspects of cosmology. I want to learn all I can about gravity wave technology. I was not expecting the level of detail that a single event is revealing. It's very interesting that they expect to see gravity waves from objects other than black holes. That makes me wonder how much the event horizon has to do with making the gravity waves? I also wonder if gravity waves may someday tell us something about the inter structure of black holes?
