Caltech and LIGO physicists Jamie Rollins and Larry Price (www.ligo.caltech.edu) join Andy, Jesse and Matt to up the Science:Probably ratio for just one week as they discuss: Why we don't go straight through tables! What's inside an atom! Why chemistry isn't their forté! Dark matter and WIMPS! Gravity waves and what LIGO actually is! How to measure something that's smaller than the smallest thing you can think of! Putting experiments in space! What inspired Einstein to come up with relativity (hint - the two of them didn't agree on it)! How scientists fake getting a result to test each other! The feebleness of gravity!
