I've just finished reading Stephen Baxter's Proxima - a gritty telling on the first interstellar voyage and colonization of P. Centauri. I like to think that, while Baxter pens audacious and fanciful stories about exploration, he is not one to simply fabricate physics like some Jules Vernian sci-fantasy. So it is with raised eyebrow that I recount a passage from the book. A second, faster spaceship has been launched from Earth. The AI pilot describes its outbound journey: "...I passed through the heliopause, the boundary where the thin wind that blows between the stars dominates over the weakening stream from the sun. But since then I have passed through many interesting domains: the radius of the sun's gravitational focus, where light from distant stars collects, after ten days, and I emerged from the Kuiper belt of Pluto-like ice worlds some days after that." [emphasis mine] What?? "radius of the sun's gravitational focus"? "light from distant stars collects"? That sounds like word salad to me. No, worse. It sounds like the writing of some budding young sci-fi author who never took a science course. Surely an esteemed author would not do such a thing. Can you make heads or tails of it?
