UFO Update: Aliven Drag and Extraterrestrial Travel
The article "UFO UPDATE" delves into a theoretical method for interstellar braking proposed by physicist Freeman Dyson. He discusses a phenomenon known as Aliven drag, accidentally discovered by Nobel laureate Hannes Aliven. This drag occurs due to electromagnetic interactions between a spacecraft and charged plasma in space, causing a slowdown.
Dyson explains that for a starship moving at near-light speeds, Aliven drag could be a viable braking mechanism. He proposes that the braking system need not be a solid mass but could consist of a network of long, thin wires, each about one micron in diameter, spaced ten meters apart. These wires would catch plasma energy to slow the craft.
A significant implication of this braking system is that it would leave behind "long, hot trails in space," described as skid marks. These trails, composed of hot plasma, could potentially be detected by radio telescopes on Earth, serving as a signal for extraterrestrial intelligence (SETI).
Dyson acknowledges that no such skid marks have been observed yet. He suggests that SETI researchers might not be actively searching for these specific signs. However, he remains optimistic about the possibility of other species exploring space, stating, "There's no evidence for it, but there's no evidence against it either." He emphasizes the importance of continuing to "keep devising ways of conducting the search."
The article also touches upon the accidental discovery of Aliven drag by Hannes Aliven when the Echo 1 satellite experienced an unexpected slowdown. The concept is presented as a problem that could be tackled by a graduate student.
Recurring Themes and Editorial Stance
This issue of OMNI magazine appears to focus on speculative science, futurism, and the potential for technological advancements to alter fundamental aspects of human existence, such as mortality (Electronic Soul). It also engages with popular science fiction (Dune) and broader questions about extraterrestrial life and interstellar travel. The editorial stance, as reflected in Dyson's comments, is one of scientific curiosity, open-mindedness, and a proactive approach to investigation, particularly in the field of SETI.
