Everything I learn about the world, whether it's the simple arcana of how commercial products are manufactured and designed and how they reach our shelves and where the chips come from and who does the code, to more profound things like whether or not a black hole might be penetrable as a wormhole, whether or not universes might be accessible from here, whether space can be stretched and compressed to enable faster-than-light travel without violating physical law - all of those things have tremendous story potential.

You need a human story to intersect those points of interest with real stakes on the line, and then things start to be fun, where you can see the ramifications, you see the impact on people's lives of big changes - like taking a man of science, like a surgeon, and robbing him of his understanding of the universe and forcing him into a newer and wider understanding.
