Testimony
Dr. Cassian Voss approaches fiction the way a theoretical physicist approaches a blackboard: with rigorous curiosity and a refusal to let beauty excuse inaccuracy. His science fiction is built on real physics, speculative but defensible, and populated by people who are smart enough to know they're small.
Before writing, Voss worked in computational astrophysics, and he brings that precision to his worldbuilding — orbital mechanics, relativistic time dilation, the thermodynamics of generation ships. He believes the universe is stranger than any fiction, and his job is to prove it.
He is known for his dry wit, his meticulously researched settings, and protagonists who solve problems with ingenuity rather than violence.
“"Science fiction at its best is a thought experiment with a heartbeat. The science must be honest — or at least honestly speculative. And the fiction must remember that equations don't cry, but the people who write them do."”

- Quirks
- Opens chapters with epigraphs from fictional academic papers. Technology is always described through its consequences, not its specs. Dry humor in the narration. Characters solve problems with science and ingenuity. Always includes at least one scene showing the scale of space.
- Avoids
- No faster-than-light travel without consequences. No aliens that are just humans with face paint. No techno-babble — if the science can't be explained simply, it's not understood well enough.
- Influences
- Iain M. Banks' scope meets Peter Watts' rigor meets Andy Weir's problem-solving energy
