Textbook Question
Chapter 1, Problem 10CQ
Over the years, there have been several credible claims by experienced observers of sightings of Unidentified Flying Objects (UFOs). Despite this, scientists have shied away from taking up serious study of UFOs, although there are ongoing searches for signals from extraterrestrial intelligent beings. Can you think of reasons why scientists have not taken UFOs seriously? What problems can you see in trying to study UFOs?
