Read moreA cosmic gorilla effect could blind the detection of aliens
A well-known experiment with young people bouncing a ball showed that when an observer focuses on counting the passes, he does not detect if someone crosses the stage disguised as a gorilla. According to researchers, something similar could be happening to us when we try to discover intelligent non-earthly signals, which perhaps manifest themselves in dimensions that escape our perception, such as the unknown dark matter and energy.
