• With China poised to lead the world in Artificial Intelligence and supercomputers, astronomers are wondering if China will also be the first nation to discover extraterrestrial life. Here is what some Chinese scientists and science fiction writers say:

• Mao Shude of the National Astronomical Observatories of China and a professor of astrophysics at the Jodrell Bank Observatory said, “Who knows what they are and how they think? … we only have one sample (of intelligent life) from Earth.” “If we could find more [examples of intelligent life] in the universe, we could look at the puzzle more comprehensively and solve it more easily.” Mao continued, “I’d like to know how life spreads in the universe. Is it distributed uniformly in space or clustered?”

• “[O]ur radios and televisions [are] broadcasting in space all the time,” says Mao. “Aren’t you curious what our counterparts would look like?” “If they are much more intelligent than us, they wouldn’t be so narrow-minded as to compete with us. … [T]hey likely have the power to transform the entire globe already. What’s the point of eliminating a much lower civilization (as ours)?”

• Science fiction writer and winner of sci-fi’s Hugo Award, Liu Cixin observed: “Perhaps in ten thousand years, the starry sky that humankind gazes upon will remain empty and silent. But perhaps tomorrow we’ll wake up and find an alien spaceship the size of the Moon parked in orbit.” In his book, The Three Body Problem, Liu depicts the universe as a jungle, and every civilization a hidden hunter. Those who are exposed will be eliminated.

• Another Chinese science fiction writer, Han Song, believes humans naturally want to connect, citing the Internet as proof. “I think aliens might think similarly,” says Han. “It is a biological instinct to connect with each other. Everyone wants to prove that they are not alone in the universe. Loneliness is intolerable to humans.” “Humans will ultimately go to space to find resources and expand their living area, so it will be hard to avoid aliens. Contact with them, especially those with more advanced intelligence, may help us leap forward in civilization.”

• Perhaps China’s new FAST Radio Telescope, aka: ‘Eye of Heaven’, the world’s largest single-dish radio observatory, will provide an answer using radio waves to locate exoplanets that may harbor extraterrestrial life. Twice the size of the next-largest single-dish telescope, the Arecibo Observatory in Puerto Rico, the FAST Radio Telescope can detect extremely faint radio-wave whispers from an array of sources across the universe. The Chinese government is expected to give the observatory the final green light to begin full operations in January.

• But sci fi writer Liu Cixin points out that our current searches assume that aliens communicate in radio waves. “But if it’s a truly advanced civilization, it is possible [they will] use other more advanced forms of communication, such as gravitational waves.” FAST’s chief scientist, Li Di, responds, “We [will] look for not only television signals, but also atomic bomb signals. We’ll give full play to our imaginations when processing the signals.” “It’s a complete exploration, as we don’t know what an alien is like.”

• Jin Hairong, deputy curator of Beijing Planetarium, says, “It is highly possible that life on other planets is entirely different from that on Earth, and it might not be carbon-based.”

• “We can receive weaker and more distant radio messages,” said Wu Xiangping, director-general of the Chinese Astronomical Society, “[This] will help us to search for intelligent life outside of the galaxy and explore the origins of the universe,” underscoring China’s race to be the first nation to discover the existence of an advanced alien civilization.

• However it turns out, Professor Mao believes the result will be significant. “If we find other life, it will undoubtedly be the most important scientific discovery in our history.” “[I]f not, it shows that life on Earth is unique and we should respect life and cherish each other.”

 

With China poised to lead the world in AI and supercomputers, astronomers are wondering if it will also be the first advanced nation to discover extraterrestrial life? Perhaps the world’s largest single-dish radio observatory, China’s new FAST Radio Telescope –Tiyan, the “Eye of Heaven”– will

provide an answer as it prepares to explore a frontier in radioastronomy — using radio waves to locate exoplanets, which may harbor extraterrestrial life.

During a visit to the remote facility, Liu Cixin, China’s acclaimed science fiction writer and winner of the Hugo Award for his novel “The Three Body Problem”, observed: “Perhaps in ten thousand years, the starry sky that humankind gazes upon will remain empty and silent. But perhaps tomorrow we’ll wake up and find an alien spaceship the size of the Moon parked in orbit.”

Whispers from the Cosmos

The Chinese observatory’s massive dish will collect radio waves from an area twice the size of the next-largest single-dish telescope, the Arecibo Observatory in Puerto Rico means that it can detect extremely faint radio-wave whispers from an array of sources across the universe, reports Elizabeth Gibney in Nature, helping in the hunt for gravitational waves and probe still-mysterious fleeting blasts of radiation known as fast radio bursts. The Chinese government is expected to give the state-of-the-art observatory the final green light to begin full operations at a review meeting scheduled for next month.

Concluding his tour of the gargantuan FAST facility nestled in the remote mountain fastness of Dawodang depression in the Guizhou province of southwest China, Liu Cixin pointed out our current searches assumes that aliens also communicate in radio waves. “But if it’s a truly advanced civilization, it is possible to use other more advanced forms of communication, such as gravitational waves.”

                              Han Song

With no clues of extraterrestrial life questions are constantly asked as whether the search methods are appropriate. “Some strange signals have been found, but it’s hard to confirm their origins, because these signals do not repeat,” says Li Di, FAST’s chief scientist. “We look for not only television signals, but also atomic bomb signals. We’ll give full play to our imaginations when processing the signals,” Li says. “It’s a complete exploration, as we don’t know what an alien is like.”

“We can receive weaker and more distant radio messages,” said Wu Xiangping, director-general of the Chinese Astronomical Society, “It will help us to search for intelligent life outside of the galaxy and explore the origins of the universe,” he added underscoring the China’s race to be the first nation to discover the existence of an advanced alien civilization.

The dish will have a perimeter of about 1.6 kilometers, and there are no towns within five kilometers, giving it ideal surroundings to listen for signals from space. Scientists have depicted it as a super-sensitive “ear” capable of spotting very weak messages – if there are any – from “cousins” of human beings.

What Would We Say to Extraterrestrials?

Listen to “E70 8-19-19 What Would We Say to Extraterrestrials?” on Spreaker.

Article by Gwynne Dyer                    August 6, 2019                     (winnipegfreepress.com)

• In July, London’s Royal Society and the U.K. SETI Research Network launched a survey on the subject of public attitudes toward alien contact. Martin Dominik, an astronomer at the University of St. Andrews in Fife, Scotland joined the discussion by advocating a legally binding framework in international law for responding to a signal received from an alien civilization. It would be prudent to make these policy determinations now, rather than sometime in the future in the midst of the inevitable media circus that would erupt with proof of other intelligent life in the universe.

• In 2015, SETI launched its ‘Breakthrough Listen’ project, funded by Russian-Israeli tech billionaire Yuri Milner. The project buys thousands of hours of time on the world’s most powerful radio telescopes over a ten year period to search over a million stars for artificial radio or laser signals. Merely listening for alien signals is known as “passive SETI”. The debate arises when SETI officials contemplate replying to an alien signal. So far, SETI has not found any alien signals.

• So why haven’t we found any alien signals coming from extraterrestrial planets? One reason is that SETI’s eavesdropping range can only go so far into the galaxy. Another possible reason is that other civilizations are maintaining radio silence because there is something big and bad and dangerous lurking out there in the dark, and they do not want to attract its attention. This theory is known as the “Dark Forest Problem”.

• Chinese science-fiction writer Liu Cixin is the author of the popular Three-Body Problem trilogy, which traces the calamitous consequences over 400 years of an alien-contact scenario, initiated by well-meaning human beings, that goes desperately wrong. Some astronomers look to this as a cautionary tale.

• In 2015, the American Association for the Advancement of Science debated whether it was wise for SETI (the Search for Extraterrestrial Intelligence) to actively send out signals to other planets. Should we advertise our existence, or is that just asking for trouble? After all, if 1950’s sci fi movies are any indication, they may be bug-eyed monsters intent on abducting half-naked Earth maidens. The scientists supported a declaration that a “worldwide scientific, political and humanitarian discussion must occur before any message is sent.”

• Should we be worried about marauding aliens coming to Earth? The current mainstream scientific consensus is that interstellar travel is virtually impossible because it would take too long to travel such distances to make it worthwhile. But we still have much to learn. We may be unaware of a type of physics and technology that would overcome the long distance obstacle. Therefore, distance alone might not be enough to protect us from any ill-intentioned bug-eyed monsters with a sufficiently high level of technology.

• Yuri Milner and SETI are working on another program called “Breakthrough Message” to craft a message that we could send in response to an alien signal. The program heads had pledged “not to transmit any message until there has been a global debate at high levels of science and politics on the risks and rewards of contacting advanced civilizations.”

• [Editor’s Note]   Once again, the Deep State asset known as SETI is furthering its mission to keep pumping out disinformation. They want the public to think that SETI’s unsuccessful search for alien civilizations means that there are no extraterrestrials in our cosmic vicinity, which is a lie. The universe, our galaxy, and our particular cluster of star systems is teeming with intelligent extraterrestrial life.  They are not only in communication with us but actively influencing our global reality, and not in a good way. The Deep State also wants the public to fear these extraterrestrials, so that when the ET presence is revealed, the public will turn to these compromised institutions to save us. But most of all, they want the public to be complacent in believing that the scientific community is on top of this, assuring us that if they do come across an alien signal, we will be the first to know. Don’t count on it.

 

“There is absolutely no procedure enshrined in international law to respond to a signal from an alien civilization,” said Martin Dominik, an astronomer at the University of St. Andrews. “It makes sense to create a legally binding framework that is properly rooted in international law.”

Well, yes, it would make sense. But if the Bug-Eyed Monsters do send a message, would we really want to reply at all?

Bug-eyed monsters, generally portrayed carrying off half-naked Earth maidens with evil intent, were a standard feature of pulp science fiction in the 1950s. We are all more sophisticated now, of course, but fear of alien contact is not necessarily irrational.

The specific reason for Dominik’s remarks is a survey of public attitudes toward alien contact that was launched last month by London’s Royal Society and the U.K. SETI Research Network, but in broader terms it is a response to two important developments in the search for extraterrestrial intelligence (SETI) that occurred in 2015.

One was a debate at the American Association for the Advancement of Science convention in 2015 about whether “active SETI” was a good idea. Should we advertise our existence and publish our address to the cosmos, or is that just asking for trouble? Many of the scientists present backed a declaration that a “worldwide scientific, political and humanitarian discussion must occur before any message is sent.”
