A team of international researchers, led by scientists from the University of St Andrews and the SETI Institute of Mountain View, California, is redefining the scale of alien detection.
What are the consequences for the human race if we encounter an extraterrestrial intelligence? If you see a story about foreigners on TV or online, what should be your enthusiasm? A new study, published in International Journal of Astrobiology reorganizes a tool long used to clbadify potential signals from extraterrestrial intelligence, thus making it suitable for the modern world of news and social media.
In 2001, the Rio Scale is a tool used by astronomers who seek extraterrestrial intelligence (ETI) to help communicate to the public "how much they should be excited about what has been observed" . The scale measures the consequences for humans if the signal comes from extraterrestrials, as well as the probability that the signal really comes from extraterrestrials, and not a natural or human phenomenon. The scale gives a score between zero and ten, so the audience can quickly see how important a signal is.
"The whole world is experiencing the Richter scale to quantify the severity of an earthquake and earthquake and then refined that more data is consolidated," said Jill Tarter, co-author Founder of the SETI Institute. "The SETI community is trying to create a scale that can accompany reports of all claims of extraterrestrial intelligence detection and be refined over time as more data become available.This scale should convey both the importance and the credibility of the claimed detection. is an attempt to update the scale to make it more useful and compatible with current modes of information dissemination, as well as to provide the public with ways to become familiar with the scale . "
" In recent years, learning the truth about these stories is becoming more difficult. As such, an updated Rio Scale is needed
The new study, led by Dr. Duncan Forgan at the University's Exoplanet Science Center, highlights the changing nature of the news media, growing information 24 hours a day. 24 and the new social media landscape. Coupled with an increase in ETI detection efforts by teams around the world, Rio's scale is more than ever needed, and it must remain relevant when communicating to the public ' foreign signals ".
The International Team of Researchers of the Rio-wide Revision (Rio 2.0) aims to bring consensus across academic disciplines, when clbadifying signals likely to indicate the Existence of advanced extraterrestrial life. Rio 2.0 can quickly calibrate the audience's expectations of a signal signal, and educate them on how SETI scientists actually evaluate a signal, from its initial detection to the various verification steps needed to determine whether a signal comes in a credible way from the EIT. to research is also the development of a single set of consistent terminology to discuss signals, both among researchers and the media.
The team released an online Rio Scale calculator, an interactive tool for scientists and science communicators and give advice on how to use it to better account for the ETI in the media.
Principal investigator, Dr. Duncan Forgan of the Exoplanets Science Center of the University of St Andrews, said: "It is absolutely crucial that so important that the discovery of intelligent life beyond the Earth, we do it clearly and cautiously. "Having Rio 2.0 allows us to clbadify a signal quickly in a way that the general public can easily understand and helps us keep its confidence in a world filled with false news.
The new Rio Scale was submitted to the Standing Committee of the International Academy of Astronautics on SETI for official ratification.
