Abstract

Since the beginning of my career, I have been fascinated by the phenomenon of gravitational waves—ripples in space and time that spread at the speed of light. At first, my interest was simply in understanding the concepts, but once I realized there was a possibility to actually detect gravitational waves, I was hooked. I decided to join the efforts to design and build gravitational wave detectors, and I worked on that challenge for a few decades until the first successful detection in 2015. In this article, I will tell you about how a gravitational wave detection instrument called LIGO came about, how my students and I helped improve it, and what the future holds for LIGO and for other gravitational wave detectors that could revolutionize our understanding of the universe.
