chunk: Kelvin and Gordon then discover Snow's body stashed away in a ceiling vent and realize that the Snow they have been interacting with is a replica. Snow admits to being a replica and explains that upon being dreamed into existence, he was attacked by his creator and thus killed the "original Snow" in self-defense. The Snow replica tells them that repeat usage of the apparatus has drained the ship's fuel cell reactor, making a return trip to Earth impossible. Furthermore, Solaris has reacted to the behavior of the humans by 'exponentially' increasing its mass, thereby gravitationally pulling the space station inexorably toward the planet. Gordon and Kelvin begin prepping a smaller space vehicle called Athena to escape.
