All the crucial pieces of Heinlein’s novel are here, including Pete (the cat) and a single, consistent timeline.

- Time Periods
- Circa AD 1960 to 1969: Soichiro as an infant, 1968
- Circa AD 1970 to 1999: Soichiro in 1985 and 1995
- Timeline Models
- Single Consistent Timeline: The characters don’t realize it (for example, “We’re now in a rewritten future.”) but everything we see happening in 1995 is consistent with Soichiro’s later visit to that year. No rewritting necessary, thank Heinlein!
- Time Travel Methods
- Time Catapults: We’re gonna say that the professor’s time machine flings Soichiro into the past.
- Time Platform
- Themes
- Ex Nihilo Knowledge: When Soichiro returns to 1995, he conveys knowledge to Taro about 2025. For me, this is what Taro later refers to when he says “It loops.”
- Long Sleep, Cryogenics, Etc.
- Money Difficulties: While asleep, Soichiro goes broke.
- Fictional Tags
- Robots, Androids, and Cyborgs: We wish robot PETE hadn’t been added to Heinlein’s story, but perhaps in a film he was needed as a foil for Soichiro.
