Earthling scientists carry out a plan to call ET

Earthling scientists carry out a plan to call ET:

It’s been nearly 40 years since humans first tried contacting extraterrestrials with radio telescope technology, and as far as we know, nobody has said “hello” back to us.

If earthlings want to communicate with someone, perhaps we should change the channels to connect with an intelligence that actually knows what we’re saying -- and vice versa.

A team of scientists is developing a new series of protocols to more finely tune our efforts to talk to another civilization in the nearby galactic neighborhood. And they’re hoping to enlist the public’s help.

The receiver of the Arecibo radio telescope hangs suspended by cables over the 1,000-foot dish of the radio telescope below it. Two of the three masts supporting the receiver can be seen in the background, lit with aircraft warning lights.

In 1974, researchers sent the first message into deep space, using the Arecibo radio telescope in Puerto Rico. Targeting a cluster of stars 25,000 light-years away, the “greeting” included information on human DNA and graphic representations of a human and our solar system.

The Arecibo radio telescope built in a giant natural valley is the biggest and most sensitive in the world. It is located in the municipality of Arecibo in the northern part of the island of Puerto Rico, an American territory.

“Finding intelligent life is very improbable. There could be life such as human beings 100 years ago, when we didn’t have the capability of building radio telescopes. So, suppose there is life on another planet of such technical advancement, then they won’t be able to see the signal,” said Dimitra Atri of the department of physics and astronomy at the University of Kansas.

Atri and his colleagues Jacob Haqq-Misra of Pennsylvania State University and Julia DeMarines from the International Space University in France, urge new protocols for future attempts to contact extraterrestrial intelligence.

“When you send radio signals, you send them at a specific frequency, and if the detector at that end is not tuned to that frequency, they will not be able to detect it,” Atri stated.

He believes that’s been one of the problems facing scientists who conduct the ongoing search for extraterrestrial intelligence at the SETI Institute in California.

“Up to a few years ago, before they had the Allen Telescope Array, their frequency bandwidth was limited,” Atri explained. “So they could not detect any signals out of that bandwidth. Even if someone were trying to contact us, we don’t know.

“Our galaxy is filled with hydrogen, which emits at a wavelength of 21 centimeters, and if there’s an intelligent civilization anywhere, they would be studying the galaxy, so if you try to send a signal close to that frequency, their detectors might detect it.”

Scientists hope to enlist the public’s help in developing new protocols on how the messages should be sent and to which frequency we should be transmitting the signals to the extraterrestrial civilization.

“There’s one major problem: how you encode the signal. We have been encoding the signals the way we can understand or the way our computers can understand,” said Atri.

“If, for example, you make a keynote presentation on a Mac, there’s no way you can open it on a Windows machine because you have to have software at the other end that can understand the file format. So if you want to send a music or a video file or a picture into space at a certain frequency, how would a person at the other end know how to encode this into a voice or video signal? That’s the main problem.”

Atri explains that in addition to developing the proper encoding system for a signal to be sent to space, there’s also the question of whether it should be delivered as a radio wave or as part of a laser beam aimed at the cosmos.

Within a few months, Atri and his colleagues will launch an interactive website so that anyone -- scientists and the general public -- with Internet access can go online and suggest the kind of message, encoding or transmission medium that should be used to send signals into space.

But what about the argument from scientists such as astrophysicist Stephen Hawking who actually believe it would be dangerous for earthlings to announce their presence in the galaxy?

“If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,” Hawking declared last year in his Discovery Channel series “Into the Universe with Stephen Hawking.”

“Well, the thing is, Stephen Hawking is not an expert in interplanetary sociology. In fact, there is NO expert of interplanetary sociology on Earth. So we don’t know what the other civilization would be thinking,” Atri said.

He also suggests that the radio and television signals that have left Earth over the past 100 years may not have traveled so far as to announce our presence to another world.

“It’s like using a wireless Internet at home. You have a router that lets you use it in any room you want or maybe in your neighborhood you can access it. But if you go to a different city, there’s no way you can access that Internet, because the signal dies out very quickly.”

Atri and his colleagues believe the simplest way to contact another species is to identify potentially habitable planets and transmit our signals directly to those planets. Atri’s team’s research will be published in an upcoming issue of the journal Space Policy.

But there’s still a little bit of frustration in sending a signal to another civilization and having to wait decades or hundreds of years for some kind of intelligent response. While realistically, we may all be dead by the time that happens, Atri is more optimistic.

“Well, our great-grandkids would be thankful that we sent the signals.”

Although there have been many unexplained sightings in the town of Lajas, the situation there has been hyped by the amount of lies and exaggeration by a group of so-called, "ufologists" who ignore other areas of Puerto Rico to promote tourism in Lajas. That was evident when my wife and my daughter confronted a terrifying experience in the town of Aguada with extraterrestrials and that group of charlatans refused our plea for help. Of course, if it happened in Lajas they would have jumped on the opportunity for fame and tourism for that town. Those hoaxes and lies were approved and sanctioned by the then mayor of that town who named route 303 "The extraterrestrial route". The idea of building an "UFOport" (ovnipuerto), “la llorona sightings" and the biggest hoax of them all, "that a UFO crashed there" all this could only be found in a science fiction novel.

About me

Ufologist, criminal investigator, musician, artist and writer.

I worked 20 years for the New York City Department of Correction. First as a Correction Officer for 4 years, Captain for 12 years, and as a Deputy Warden for 4 years. As a law enforcement officer and supervisor, I have conducted countless of criminal investigations, some for unimaginable allegations.

On June of 2005, after my retirement, I moved to Puerto Rico with my family where my wife and my daughter faced extraordinary experiences with extraterrestrials. These alien encounters, subsequent abductions of my wife and the lack of help from so-called, "ufologists" here on the island, prompted me to become involved in the field of ufology and in the need to help others who have had similar experiences.


PRUFON, Puerto Rico UFO Network, Inc., is a nonprofit organization which conducts serious no nonsense UFO investigations. Our aim is to find the truth and answers to some of the toughest questions pertaining to UFO sightings, alien encounters and alien abductions, etc. We are not affiliated with any other ufology organization in Puerto Rico or in the world. PRUFON was founded in the city of Aguadilla, Puerto Rico on September of 2009 to share with the public what we have accomplished and researched in the related fields of ufology.

This internet network ( offers a different perspective on life, and works hard to keep you informed about unexplained phenomena occurring on the island of Puerto Rico and in the Caribbean. We collect and gather information dealing with the Unidentified Flying Objects (UFOs) and other unusual events that the mainstream news media and science fail to expose to the public, fail to study or acknowledge.

Any unusual encounter or sighting that you have had and wish an investigation and/or wish to publish it on this website, contact PRUFON at You will remain anonymous if you state it in writing.
