The detection of gravity waves -- a first for mankind -- has also produced some great science publicity such as this. The producer of the video has taken a complex topic and boiled it to its essentials to facilitate understanding. The complexity lies in the building of the two machines in the first place. Every source of extraneous vibration had to be neutralized for the two interferometers to work. It took years of effort to get that done. Rather than go into the story of building the laser systems, the video explains the why and what in clear terms that a school child could understand. Now that we know that gravity waves exist and we have observatories to listen for them, a new branch of science has opened that will take generations to explore and understand. Look for a Nobel prize to go to the developers of the machines. They deserve it.
