The Daleth Effect

The Daleth Effect is a 1970 science fiction novel by Harry Harrison that centers on a groundbreaking discovery in space travel technology. An Israeli scientist named Arnie Klein develops a revolutionary method for space travel called the Daleth effect, which has both peaceful and military applications. The story follows Klein's decision to defect to Denmark to prevent his discovery from being weaponized. He conducts experiments with the technology, including modifying a submarine for space travel, but international attention intensifies when the device is used in a rescue mission to the Moon. The novel was published under two titles - The Daleth Effect in the US and In Our Hands, the Stars in the UK. It was serialized in Analog magazine before its book release and has been translated into multiple languages including German, Spanish, Italian, and Chinese. The narrative explores themes of scientific responsibility and the tension between technological progress and military power. Like many classic science fiction works of its era, it raises questions about the role of scientists in controlling their discoveries and the competing interests of different nations in technological advancement.

Readers describe this as a straightforward science fiction story about anti-gravity technology and its implications. The book has limited reviews online.
