www.nytimes.com/2015/03/28/opinion/sunday/messaging-the-stars.html?_r=1 NEW YORK TIMES / SundayReview | Opinion Should We Keep a Low Profile in Space?By SETH SHOSTAK MARCH 27, 2015 MOUNTAIN VIEW, Calif. — For more than a half-century, a small group of astronomers has sought intelligent company among the stars. They’ve done so by turning large radio antennas skyward, hoping to eavesdrop on signals from an advanced society. It’s a program known as SETI, the Search for Extraterrestrial Intelligence. But now some researchers propose that we should do more than simply don headphones and await E.T.’s call: We should make serious efforts to encourage a response from putative aliens by deliberately transmitting our own messages. It’s a simple idea, akin to tossing a bottle into the cosmic ocean. But recent arguments for what’s termed active SETI have loosed a storm of controversy, one that has even washed into the halls of academe. Why is this? Why has the sending of dispatches to worlds many trillions of miles distant suddenly become a hot-button issue? The simple answer is that there’s now a perception that advertising our existence could be a mortal threat to the planet. The reasoning is this: While no one has yet offered decisive proof for life beyond Earth, in the past two years astronomers have learned that tens of billions of habitable planets suffuse our galaxy. Consequently, to believe that only Earth has spawned intelligence is to insist that our world is the site of a miracle. That point of view rarely appeals to scientists. The aliens could very well be out there. And that realization has spurred a call by some for broadcasts intended to elicit a communication from at least the nearest other star systems. But we know nothing of the aliens’ possible motives or behavior. Therefore, it’s conceivable that betraying our existence might prompt aggressive action from space. Broadcasting is likened to “shouting in the jungle” — not a good idea when you don’t know what’s out there. The British physicist Stephen Hawking alluded to this danger by noting that on Earth, when less advanced societies drew the attention of those more advanced, the consequences for the former were seldom agreeable.

Once again, Hawking says, "Be careful!"Stephen Hawking Is Still Afraid of AliensBy Mike Wall, Space.com Senior Writer September 25, 2016

Humanity should be wary of seeking out contact with alien civilizations, Stephen Hawking has warned once again.
In 2010, the famed astrophysicist said that intelligent aliens may be rapacious marauders, roaming the cosmos in search of resources to plunder and planets to conquer and colonize. He reiterates that basic concern in "Stephen Hawking's Favorite Places," a new documentary streaming now on the CuriosityStream video service.
"One day, we might receive a signal from a planet like this," Hawking says in the documentary, referring to a potentially habitable alien world known as Gliese 832c. "But we should be wary of answering back. Meeting an advanced civilization could be like Native Americans encountering Columbus. That didn't turn out so well."
For what it's worth, some other astronomers believe Hawking's caution is unwarranted. Any alien civilization advanced enough to come to Earth would surely already know of humans' existence via the radio and TV signals that humanity has been sending out into space since 1900 or so, this line of thinking goes.
The alien musings are just a small part of "Stephen Hawking's Favorite Places." The 26-minute documentary shows the scientist zooming through the cosmos on a souped-up CGI spaceship called the "S.S. Hawking," making five separate stops.
Hawking observes the Big Bang that created the universe, visits the monster black hole at the center of the Milky Way, journeys to Gliese 832c and tours Saturn in Earth's own solar system. Then, he makes a final stop in Santa Barbara, California, which Hawking calls "my home away from home."
"In 1974, Caltech [the California Institute of Technology] offered me a job in California," the Englishman Hawking says in the documentary. "I jumped at the opportunity. In the sun with my young family, it was a world away from the gray skies of Cambridge, [England]. I've traveled the globe, but I've never found anywhere quite like this."

Read more: theedgeofreality.proboards.com/thread/5585/keep-low-profile-space#ixzz4LIwPPLbe***** And, as someone has said before, should we be concerned with what "they" hear on tv and radio? Have "they" been hearing this "chatter" for so long, that they can understand our language and understand the entertainment factor? Is Hawking actually going on some sort of theory that "they" remain hidden from us, so we should do the same?

He's afraid aliens will treat us the way our forefathers treated native Americans.....

As some people have been "afraid" that the "black man" wants to treat the "white man" as they feel that their ancestors ( and now themselves) have been treated. ?? Any hope for changing this "seemingly" repeating pattern? Why haven't "aliens" already taken advantage of our naivte? Is there anything really valuable here to be plundered? Maybe there really are so many habitable worlds, that each "world" is known for its "produce", and "they" harvest at seasons (years) much like a human farmer would. . . even letting a world lie fallow for a period of time, or let it "burn itself out". . . . Or dropping a "plague of grasshopper" from time to time. . . IF you had the technology to traverse Space in days instead of years; knew all the " doorways " to different galaxies; AND it was CONSIDERED CRIMINAL to pretend to be in "relations with the workers" of different worlds. . . So many, many options. . . And if I'm an animal that was "tagged" and released, I wonder what information I am providing "them"? www.cbsnews.com/news/ocearch-great-white-sharks-birthing-site-montauk-long-island-discovered-chris-fischer/ (Gee. .

The team sent a message that includes a scientific and mathematical "tutorial," as well as 33 short musical compositions by artists in the Sónar community. The team beamed this message out in binary code at two different radio frequencies on Oct. 16, Oct. 17 and Oct. 18, using the 105-foot-wide (32 meters) European Incoherent Scatter Scientific Association (EISCAT) radio antenna in Tromsø, Norway. Though the message was designed to provoke a response from an intelligent advance civilization living on GJ 273b, the main goal in sending the communication involved laying a foundation for the future, said Douglas Vakoch, president of METI (Messaging Extraterrestrial Intelligence) International, a San Francisco-based nonprofit. [13 Ways to Hunt Intelligent Aliens] "It is a prototype for what I think we would most likely need to do 100 times, or 1,000 times, or 1 million times," Vakoch told Space.com. "To me, the big success of the project will come if, 25 years from now, there's someone who remembers to look [for a response]. If we could accomplish that, that would be a radical shift of perspective." "It's really hard to imagine a scenario in which a civilization around Luyten's star could have the capacity to come to Earth and threaten us, and yet they're not able to pick up our leakage radiation," he said, referring to the TV and radio signals that have been slipping out into the cosmos from Earth for more than half a century. The Luyten's star project, known as "Sónar Calling GJ 273b," is a collaboration involving METI International; the Institute of Space Studies of Catalonia in Spain; and Sónar, a music, creativity and technology festival in Barcelona, Spain. "Doing it in partnership with the Sónar festival is a way that we can respect the necessity of incorporating a scientific perspective but also to recognize that doesn't capture the fullness of the human spirit," Vakoch said. "The challenge of constructing any interstellar message is trying to anticipate what you and your recipient have in common," said Vakoch, "One thing we can guarantee is they won't be native speakers of English or Swahili or Chinese." And the same problem applies to any incoming message to Earth. "It's very reasonable to think that we will know there's an extraterrestrial out there, that we will have a message that is distinctly artificial, but that we won't be able to decipher it."

Any extraterrestrial civilizations possessing technology (including viable interstellar travel) capable of threatening us almost certainly possess the much simpler technology to detect us - and we've been a detectable civilization (TV, radio, radar) for decades.
