"The new science of space speech by Vincent H. Gaddis" is a popular science essay written in the mid-20th century. It examines how humans might detect, interpret, and reply to messages from extraterrestrial intelligences, drawing on radio astronomy, mathematics, and studies of animal communication to outline practical pathways toward interspecies and interstellar understanding. The essay frames the challenge as twofold: establishing contact with intelligent nonhuman beings in person and building a universal method for radio exchange across space. It surveys efforts from giant radio telescopes and the early SETI attempt Project Ozma to Dr. John C. Lilly’s “Project Dolphin,” where dolphins mimic human speech at high speed, suggesting a path to cross-species language. Gaddis then proposes mathematics and timing as common ground, highlighting systems like Lincos and the use of geometric concepts and pictorial symbols to build meaning step by step. He reviews puzzling historical signals and echo anomalies, including a 1924 Mars-listening effort and the idea of an automated probe that might respond to triggers, while warning of the huge time delays and risks of misinterpretation. The piece closes with the cultural stakes—drawing on psychological studies that foresee shock and change if superior civilizations are found—and argues for preparation, patience, and careful methods so that, when contact comes, humanity can answer wisely.
