Why aliens never get in touch with us
Washington: A team of scientists has said that no matter how much we try to contact extra terrestrial life, we may never get any response because we are going about it all wrong.
Humans began sending messages into space, starting in 1994 with transmission sent using the Arecibo radio telescope to a star cluster 25,000 light years from Earth.
A trio of researchers - Dimitra Atri from the University of Kansas, Julia DeMarines from the International Space University in France, and Jacob Haqq-Misra from Pennsylvania State University - offer an explanation for our failure to communicate.
The team believes that as the broadcasts became more complex and the types of content increased, the absence of an established protocol "has produced unorganized or cryptic messages that could be difficult to interpret."
They said that any future messaging protocol for messaging to extraterrestrial intelligence should account for a myriad of attributes, such as signal encoding, message length, and information content.
The team added that post development the protocol would be disseminated for testing on humans around the world, cutting across cultural boundaries.
"An effective message to extraterrestrials should at least be understandable by humans, and releasing the protocol for testing will allow us to improve the protocol and develop potential messages," Fox News quoted the authors as writing.
"Through an interactive website, users across the world will be able to create and exchange messages that follow the protocol in order to discover the types of messages better suited for cross-cultural communication."
The study appears in the journal Space Policy.
