The Impossible World Named Earth
An alien communicates telepathically with a writer from Earth, but none of his companions believe that there could be a planet other than theirs.
| StoryTitle2 = The Boomerang World | Synopsis2 = In 1966, interplanetary travel became possible thanks to the discovery of an element called Dionesium, but 100 years later all the reserves have dried up. Pilot Orton Boone is sent to find more and intercepts a distress signal from the asteroid Hermes, which has the Dionesium he needs. However, he can’t land his ship because of the reverse-gravity radiating off the asteroid.
Hermes's inhabitants explain that they are political prisoners exiled from the planet Asteroidia, which became the asteroid belt after its dictator's frequent use of nuclear bombs weakened its structure. Boone uses hydrogen balloons to be pulled "up" by the reverse-gravity and prevents the asteroid from falling into the sun by fashioning crude Dionesium rockets.
| StoryTitle3 = The Patent Planet | Synopsis3 = A security officer from the United Planets named John Carrick is assigned to the Interplanetary Patent Office on an artificial satellite near Pluto. Nothing has been stolen, but someone seems to be disassembling and reassembling machines in the dead of night to try and figure out how they work. Whoever it is, they work so fast that their surveillance equipment can’t clearly identify them.
John tries to interrogate a Plutonian robot-maker named Awlo Uthan, but is overwhelmed by Uthan's surprising strength. John realises that Uthan is actually an android constructed by a metallic alien he'd been pretending was his robot. Lucky for the metal man, the people of Earth are happy to lend their technology to save his dying planet.
| StoryTitle4 = The Robinson Crusoe of Space | Synopsis4 = Space Cabbie now has a parrot-like alien named Gabby as a pet. A few months ago, he traveled through the rings of Saturn and his taxi became radioactive, and he was banned from all planets. He took refuge on an asteroid and became, in his own words, a Robinson Crusoe of space, collecting fruit and raising cattle, until he noticed that something was taking away his radioactive glow. He searched the entire asteroid, even scaring off a spaceship whose pilot initially thought Cabbie had found gold there. After practically giving up on the search for the material that briefly absorbed his radiation and cursing his luck, Cabbie finally realized: it was Gabby.

Also, the aliens have advancements in some areas and not others, for example, they can build the mind machine but no mechanical vehicles. * "The Boomerang World" is set on an universe (Earth-54?) where the Earth began spacefaring on 1966, reaching the Moon, after the discovery of an element named dynium.
