I Visited the First Gravitational Wave Detector! LIGO | STELLAR

Thank's Dianna, I love your exuberance for physics especially in this episode. I love that trait in you. You tell us with vigor how it works. As an ex Military electronic eng doing work for '5 eyes alliance' , you should google that,  it invloved Edward Snowden which may ring a bell!, which includes your NSA and 4 other nations doing sigint and elint, spook work. We used lasers in similar way to get audio recordings of what people were saying inside rooms, same principle infrared laser pointed at window or curtain and the phase shift in returned reflection due to subtle movement on surfaces,from sound waves:- a glass cup, window, table cloth, over head light or candle. It's difficult to initially set up getting all the angles correct to receive reflected lasing and compare phase shift with original laser before reflecting off subtle movements of reflected surface.  Essentially it's the same thing / concept. I remember laughing so much when Myth Busters did an episode on this and Adam Savage and Jamie Hyneman found it as frustrating as we did to get it aligned correctly, but once set up correctly it works a peach. I would like you to do the same experiment . It would be so much fun to watch you do it . Your enthusiasm, passion and exuberance in physics is the same I have for electronics, quantum mechanics, astronomy and cosmology. I have to know how things work ever since I was a child. My first favorite website when WWW started which is still going is called 'How stuff works. ' My big fascination as a child was radio, Marconi, Faraday and Tesla were my champions at 6 yrs old studying after school at night technical college to get full amateur radio licence before I joined the Royal Australian Navy and did my electronic communications apprenticeship. I was gifted in understanding the things I was curious about and I'm so grateful for that natural gift of understanding and curiosity, your passionate exuberance reminds me of myself. I'm now medically retired and still passionate about how things work. Your doing a fantastic job of HAPPY PHYSICSING! . I subscribed to your channel a few weeks ago. You bring me so much joy and excitement watching your vids. Keep up the great work. Kind regards, Ken
