There's no fancy machine learning needed to detect some "bright" LIGO signals (some of the first blackhole-blackhole mergers). Given a set of template signals, a matched filter tries to find the one that best matches the noisy signal your instrument recorded. In order for a MF to work, what you really need is a good understanding of the noise in your instruments observations -- and there're very few people in the world better at that than LIGO folks. LIGO spent almost 20 years in construction and R&D, and almost 30 in planning. When you hear stories about how they can detect trucks miles away, and detect the waves crashing on the coast, it's possible because of scores of PhD students' who spent years characterizing each and every component that affects LIGO's noise levels. All of this to say that it's possible to download their data online and do a quick MF analysis (I did that), and with a little bit of work you get a blindingly bright statistical significance of 20-sigma or so. The actual result quoted in the papers was a bit higher. That's a testament to how well the instrument was built and its behaviour understood.


Calling someone's decisions poor/stupid/uninformed doesn't stem from a lack of empathy or anything like that. Empathy isn't born in a vacuum, nor is it possible to get rid of ego altogether. Ego processes my lived experiences into feelings and opinions.


How could it stem from anything else?

Agreed, but you need to keep it on a leash, or it will ruin your life.


this comment is a wonderful exercise in logic.


it sounds like they used gpt to wrote that


I didn't, that was my own analysis.

I just sound like I am GPT, because I am a pedantic autist that simply MUST split hairs about EVERYTHING

I honestly take it as a compliment


Please continue being yourself. Your commentary is delightfully refreshing!


If they had, there would be more talk about "exciting new pathways" and the like.
