I'm in the fairly same boat... though I picked my majors because of future salary. I switched from Computer Science to EE to, finally, Physics. I realized, thankfully, only 2 years into my degrees that I've always loved Physics. That's why I'll be at LSU soon for my PhD.
What is it about...
I think that's exactly how and why the detectors work, by distorting the photons. The interferometer detects any of those distortions in its field. Taken straight from http://www.ligo.caltech.edu/advLIGO/"
