Background
The series is set approximately 50 to 100 years in the future. Mankind has settled the moon, where the moon base "Delta-4" is a central setting, while the rest of the solar system is being explored. The scientist character of Professor Dr. Arthur Common has created (with the assistance of his daughter Cindy) the "Dimension Transmitter." With this device, users can overcome arbitrary distances without time delay. Via an enormous energy expenditure from the Transmitter, the Time/Space dimensions break open to allow small groups of humans to visit alien planets without transport.
Based on this premise, in this series, the protagonist Commander Randy Perkins and his friend and colleague Major Peter Hoffmann, often accompanied by the professor's telepathically gifted son Ralph, undertake voyages into alien worlds, often involving the ill-prepared Earth in intergalactic events.

“Pilate with his question “What is truth?” is gladly trotted out these days as an advocate of Christ, so as to arouse the suspicion that everything known and knowable is an illusion and to erect the cross upon that gruesome background of the impossibility of knowledge.”
—Friedrich Nietzsche (1844–1900)
“They were more than hostile. In the first place, I was a south Georgian and I was looked upon as a fiscal conservative, and the Atlanta newspapers quite erroneously, because they didn’t know anything about me or my background here in Plains, decided that I was also a racial conservative.”
—Jimmy Carter (James Earl Carter, Jr.)
