i saw his interview on what ever news thingy it was..kind of was surprised he jumped all over that really
It's because Andrew Siemeon, Jason Wright, and others are cautiously leaning towards this....but you're right more data is needed. There isn't a conclusion. It's entirely possible it's a natural phenomenon we've never thought of, but what I've read is the data that they have fits the theoretical models for what a Dyson swarm signature would read as if observed from afar. So, this is why the Dyson swarm is starting to lean towards being the theoretical model that fits the best with the data they currently have.
