![]() ![]() He said he was concerned that a Ukraine conflict could have broader implications and "could get out of hand". Mr Biden said a third summit with Mr Putin "is still a possibility" after the two leaders met twice last year. ![]() "Any incursion by the Russian military into Ukraine should be viewed as a major incursion because it will destabilise Ukraine and freedom-loving countries in Eastern Europe," said Republican senator Rob Portman. Republicans expressed concern about Mr Biden's remarks. "If any Russian military forces move across the Ukrainian border, that's a renewed invasion and it will be met with a swift, severe and united response from the United States and our allies," said White House press secretary Jen Psaki.īut cyber attacks and paramilitary tactics by Russia "will be met with a decisive, reciprocal and united response", she said. “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet,” Professor Hawking said, citing the arrival of Europeans in the Americas.Russian officials have repeatedly denied planning to invade, but the Kremlin has massed some 100,000 troops near Ukraine's borders. In a documentary released in 2010, Professor Hawking pointed out that, on Earth, interactions between civilisations on different levels of technological advancement tend not to work out very well for the lesser-advanced group. Scientists including Stephen Hawking have, in the past, warned that these messages could be risky. No date has been offered for the broadcast. The Nasa scientists proposed that the message be broadcast from FAST (China’s Five-hundred-metre Aperture Spherical Radio Telescope) and the SETI Institute’s Allen Telescope Array in northern California. Given the downside could be much bigger than the upside, this doesn’t sound to me like a good situation in which to take active steps toward contact.” We have very little evidence about whether this is high or low, and there is no scientific consensus. Overall, wrote Dr Ord, “the main relevant question is the ratio of peaceful to hostile civilisations. “These dangers are small, but poorly understood and not yet well managed.” ‘The downside could be much bigger’ Toby Ord, Dr Sandberg’s colleague at the FHI, made similar arguments in The Precipice, a book published in 2020 in which he analysed existential risks facing humanity.ĭr Ord suggested that it might be wise to have “public discussion” before sending messages to aliens, pointing out that “even passive SETI (listening for their messages) could hold dangers, as the message could be designed to entrap us. When Russian President Vladimir Putin picked up the phone to express his sympathy to President Bush in the aftermath of September 11 and then followed up by. “We’re not great at coordinating, but I think it is a nice exercise,” he said. “The poor aliens might already be getting various messages sent for all sorts of reasons,” said Dr Sandberg.Ī better approach than individual groups firing off ad-hoc missives, Dr Sandberg suggested, would be humanity coordinating as a species. The Arecibo message is one of several broadcasts, including some advertisements, already sent by humans into space. ![]() Given the difficulty of traversing vast spans of interstellar space, a message received even by a very advanced civilisation might amount to little beyond, as Dr Sandberg put it, “a postcard saying, ‘Wish you were here,’”. Overall, said Dr Sandberg, both the risk and the potential benefit were small. Which is a shame, because this is important stuff”. He said that the “giggle factor” surrounding the search for extraterrestrial intelligence meant that “many people just refuse to take anything related to it seriously. The message concludes with an invitation for intelligences to respond.īut Anders Sandberg, a senior research fellow at Oxford’s Future of Humanity Institute (FHI), warned that sharing such information with intelligent life presents a risk that must be considered.ĭr Sandberg told The Telegraph that, although the chance of the message reaching an alien civilisation was low, “it has such a high impact that you actually need to take it rather seriously”. It also includes the solar system’s location relative to major clusters of stars, along with digitised depictions of the solar system itself, Earth’s surface, and male and female humans. The proposed new message includes basic mathematical and physical concepts to establish a universal means of communication, followed by information on the biochemical composition of life on Earth. Improvements in digital technology mean that more information can now be broadcast. It is an updated form of the Arecibo message, broadcast in 1974 for the same purpose. Researchers at the US space agency have backed a broadcast message, dubbed the "Beacon in the Galaxy", intended to greet extraterrestrial intelligences. ![]() Nasa's plan to beam Earth's location into outer space could provoke an alien attack, Oxford scientists have warned. ![]()
