The Importance of Field Theory

Rossin Rodriguez: What is gravity fundamentally made up of? Is it a result of some quantum phenomena? Or is there any particle responsible for gravity? How fast do the gravitational waves travel through space? And what decides the limit of that speed? A lot of questions. I love it when people, because that sounds like they were burning within them and he couldn't get to sleep. He can't sleep at night. Get him off his chest. It's like pacing. That's crazy. But we have top people working on it. The laser interferometric gravitational wave observatory shortened to LIGO uses high technology lasers and interferometers where it knows the distances between two points.
