Yeah, but isn't that just a necessary step in learning? It takes knowledge off-course for a while, but then who knows at the time what the right course will be?

Yeah, but isn't that just a necessary step in learning? It takes knowledge off-course for a while, but then who knows at the time what the right course will be? Personally, I'm happy to see more theories and results around gravity and gravitational waves. When I read about physics in school and later, it was all about particles and interactions. They were talking about the theoretical Grand Unified Theory, but they only had 2 then 3 forces in the model. Gravity was always this big outlier, yet it makes the world go round (quite literally). This article talks about the ability to detect gravity waves from neutron stars (LIGO, which is quite recent), and that made me think they are like spark gap transmitters: huge bursts of energy across the spectrum. Think of the history of radio: at first they used spark gap transmitters for wireless telegraph, but in time, they refined the equipment and now we have 5G. There was another recent article about detecting the fainter gravity waves caused by earthquakes. Maybe we'll get there in our lifetimes.
