You’d be entirely correct, and that’s exactly why there’s an ongoing debate in physics and cosmology as to why there’s so much matter, and so little antimatter in the universe.

I wouldn’t say that’s particularly surprising. Most people in Lemmy and similar platforms have been here since the mass exodus from Reddit, or are programmers themselves. These groups are usually more privacy-minded, and see this as a significant privacy issue. This doesn’t really necessarily mean it’s an echo chamber though, I’ve seen a lot of people talk about how they use and like Windows, and I think the reason why they downvoted your comment (making an assumption here, I don’t see downvotes in my instance) is because it seems to be completely unprompted by anything or anyone, and a bit abrasive.

What does that have to do with echo chambers, exactly?
