I have a layperson's/nerd's interest in cosmology and physics, and have tried to read a <a href="https://www.goodreads.com/book/show/196848522-the-biggest-ideas-in-the-universe">few</a> <a href="https://www.goodreads.com/book/show/998117.Warped_Passages">books</a> about current research. Recently, I ran across some new work suggesting a pretty radical shift in theory. Not finding a great summary for the non-physicist reader, I had Google Gemini write one for me, in the style of pop-science journalism like Science News. The result, below, is 90% AI's writing, unlike <a href="https://harlanh.tech/2026/01/defensible-use-of-ai-in-writing-like-this/">most of what I write these days</a>. I served as the editor, helped it with a few rewrites and framing, and double-checked/fixed the citations. (Gemini tended to hallucinate the wrong journal, but got the content mostly right.) It's possible that there are misunderstandings of the research direction, but I think it's pretty close. And it's an interesting set of hypotheses!</p>
