Buffy was an excellent book ... never got into the series, though ... and REMEMBER, you don't have to have a ton of knowledge. The physics that we know, and human attempts to defy it (for example, overcoming radiation and zero gravity) are a rich ground of ideas. The story you read this week was a result of me finding out that thing about Jupiter and then looking it up and going "Whoa ... if we traveled the universe, and every star system has a unique relationship -- whoa!" YouTube, Wikipedia, and Chat GPT will get you a long way -- just study the Solar System, and extrapolate what might happen elsewhere as humans advance and tinker. Next week's story unfolds on the same theme with a variation: what if humans "accidentally" tinker with a little bit of mathematics known as the three-body problem, live? There is already a whole novel someone spun up just out of that idea. Good storytelling is about conveying what interests and motivates you to someone else so that they understand and feel it! I like good people, and good teamwork, and strong family relationships, and Star Trek, among many other things ... what do you like that you can share with someone else? You can always find the knowledge of what you need in science to tell the story!
