Imagery of the Planet Blue
There is quite a vast description of Planet Blue when Spike returns from her mission, as well as when Billie lands on the planet with Spike and the crew. The sentence that is repeated several times in the novel is the sentence about the new world weighing a yatto-gram. It looks like a made-up word, but the first part "yatto" has a meaning in Japanese language which roughly translates to "barely". This connection could be considered valid when thinking about the message of the novel: the repeating worlds, and the infinite opportunities given and wasted. This new world weighs barely a gram, it is barely meaningful as it will be another wasted opportunity for the humanity. The Planet Blue is a show of grotesque, with life forms in their first stages of development: "There are leaves that have grown as big as cities, and there are birds that nest in cockleshells". The creatures that live there look as though they came from nightmares and fairy tales all at once: "we saw mammals with fins and fish with legs and birds with double wings like angels...".
Imagery of the White Planet
There is a striking description of a dead planet. It is called White planet because of its empty whiteness. The planet is described in a way that is similar to what one could consider hell or inferno to look like. Its white color is not the color that one connects to positive things like sun or clean cloth. It is a white that represents nothingness. It represents "not the past, not the present and, most fearful of all, not the future."
Wreck City vs. Tech City
The contrast between the two cities, close to each other, is interesting. The cities contain two completely different ways of life. Tech City represents the technological advancement post -3 war with every comfort of orderly life. Wreck City is a place of the rebellious and outcasts. It is a city made out of collected wreck that was left after the cities were destroyed.
