Although for many experts revealing data -to potential visitors- about the position of our planet or the genetic material of living beings is risky, NASA initiated a controversial plan to attract the attention of other worlds.

Through the initiativeBeacon in the Galaxy” (Lighthouse in the Galaxy), the United States space agency plans to send images of a naked man and woman together with a “friendly message” in order to attract any extraterrestrial intelligence (ETI).

The Lighthouse information in the Galaxy will be in binary code. The scientists noted that “although the concept of mathematics in human terms might be potentially unrecognizable to ETI, the binary is likely to be universal across intelligence.”

The message also contains a time and location stamp, visual representations of the double helix structure of DNA, and a hydrogen atom.

As well as visual explanations of algebra and other mathematical operations, an illustration of the solar system, a map of the earth, and an illustration of two human bodiesone male and one female.

“This information is part of the basics expected from any message to an ETI, since allows recognition of our appearancea detail of us that a given ETI would be interested in, relevant in case further exchanges are established, or if we one day meet physically,” the scientists said.

The report proposes using the world’s largest 500-meter Aperture Spherical Radio Telescope (FAST), located in Pingtang, Guizhouu, China, to deliver the message.

It is used for the search for gravitational waves, dark matter probes and even the possible existence of signals from extraterrestrial civilizations.

These powerful new beacons, the successors to the Arecibo radio telescope that transmitted the 1974 message on which this expanded communication is based in part, can carry Arecibo’s legacy into the 21st century with this equally well-constructed communication from the technological civilization of the Land.

The project was created with support from the California Institute of Technology Jet Propulsion Laboratory, under contract to NASA, and NASA’s ROSES Exoplanet Research Program.

The message is destined for other bodies outside the Solar System.

Not all of the scientific community agrees with the idea of ​​releasing sensitive information about the human race into the void. Anders Sandberg, a senior fellow at the Oxford Institute for the Future of Humanity, is one of the detractors.

I point out that it is “very dangerous in a society struggling to survive” and that “regardless of how small the probability of extraterrestrial life is” it is a very bad idea.

And it is that, even though for some this possibility may be remote, scientists believe that it is not obsolete, so its execution has a great risk. “Many people refuse to take anything related to this seriously. And it’s a shame, because it’s a big deal,” Sandberg said.

NASA’s argument, criticized for its naivety, maintains that “logic suggests that a species that has achieved sufficient complexity to achieve communication across the cosmos will very likely also have achieved high levels of cooperation among themselves.”
