"Laser Light May Signal Presence of an Extraterrestrial Galactic Internet" -- Geoffrey Marcy, Discoverer of the 1st System of Exo Planets

Concentrated laser light in the universe may singal the presence of a technological civilizations that might be living on distant planets or in a spacecraft nearby. “Think about humanity 300 hundred years from now,” he said. “Suppose we set up a colony on another planet … the most likely way we will communicate with (humans on those planets) is with radio signals or light beams.” Marcy believes that there may be other civilizations in the universe that are years ahead of human society and might currently be communicating with radio signals in a network he calls a “galactic Internet.”

Marcy uses advanced telescopes to detect concentrated signals in space. He believes these signals may indicate the existence of another advanced civilization, because nothing in the universe is known to emit such signals. The Templeton Foundation recently granted him $200,000 for his proposal.

Marcy leads a team that specializes in searching for laser light for the Search for Extraterrestrial Intelligence, or SETI, program at UC Berkeley, a program that uses advanced telescopes to detect strong signals in an attempt to find technological civilizations in the universe.

His work is only a section of the collective effort of the organization. UC Berkeley has established a reputation as the world’s largest organization — since NASA’s 1993 SETI program — for exploring advanced life in the universe.

As more and more Earthlike planets are being discovered, some scientists feel that there is no longer anything “particularly special about Earth” that makes it uniquely conducive to life, according to Andrew Siemion, a project scientist in the UC Berkeley SETI group.

Every year, the program gathers approximately $1 million in funding, which is spread over 10 unique projects, according to Dan Werthimer, director of the UC Berkeley group. Distinct categories each concern a certain range of the electromagnetic wave spectrum, because the researchers cannot be sure at which wavelength other civilizations may be emitting their signals.

Werthimer says that the research is significant whether or not signs of extraterrestrial life are found.

“If we do not find life elsewhere in the universe, then that means we are one in trillions and should take incredibly good care of life on this planet,” Werthimer said.

Like Marcy, all of the researchers involved are respected scientists in their field who work simultaneously on other research projects in campus departments such as astronomy and electrical engineering. Werthimer and his colleagues, for example, made the first images of the black hole at the center of the Milky Way Galaxy.

“You have to know we are not searching for crop circles or flying saucers,” Marcy said with a smile.

So far, the only achievements of SETI at Berkeley are advancements in technology, as researchers have yet to find direct clues of other advanced civilizations. Nevertheless, Marcy says that these advancements are benefiting astronomy and science in general.

“I am not an optimist,” Marcy said, describing the likelihood of finding intelligent extraterrestrial life. “I would bet on my house that we would fail … But this is such an important question, the question of ‘Are we alone?’, and the only way to find out is to risk it.”

In the image at the top of the page, a glowing laser shines forth from the VLT, piercing the dark Chilean skies, its mission is to help astronomers explore the far reaches of the cosmos. To help them achieve this, professional stargazers use something that sounds as though it has come from science fiction: a laser guide star that creates an artificial star 90 km above the surface of the Earth. The laser energizes sodium atoms high in the Earth’s mesosphere, causing them to glow and creating a bright dot that appears to be a man-made star. Observations of how this “star” twinkles are fed into the VLT’s adaptive optics system, controlling a deformable mirror in the telescope to restore the image of the star to a sharp point. By doing this, the system also compensates for the distorting effect of the atmosphere in the region around the artificial star. The end result is an exceptionally crisp view of the sky, allowing ESO astronomers to make stunning observations of the Universe, almost as though the VLT were above the atmosphere in space.

Wouldn't more advanced civilizations communicate over distances of many light years with something other than radio waves?
Wouldn't it be a safe guess that they would have a much more complete understanding of gravity and space/time, and a corresponding ability to use those forces to communicate over (or through) these great distances?
Aren't we in effect acting like cavemen looking for smoke signals from people who communicate, as we do, with radio waves?

An advanced civilization will use electron quantum entanglement for communication and not electromagnetic waves(light, radio, etc).

Even they didn't develop FTL technology, they can still pack and carry synchronized quantum communication hubs when they colonize other planets.

I think SETI ppl are wasting their time and money in search for ET radio Morse code, rather their radio array can be a good scientific addition to the other light/gamma/microwaves telescopes in the study of the stars and distant galaxies.

If they are smart enough to populate other planets I don't think they would use sub-luminal communications unless there really wasn't anything else available.

Is that 300 hundred years, which is 30,000 years or 300 years?????

Doesn’t “time-of-flight”, the limitation of light speed, make presently known E/M communication useless for messaging across interstellar distances? The utility of current E/M messaging is strained even for linking our solar system, say from earth to the outer planets. If we ever get to the nearest star system, about 4 light years, messaging back to earth and return will be near zero on a utility scale. So, how useful are E/M messages except as museum value? A truly advanced civilization will solve this problem with communication technology that relies on …what? Speed of thought? THere are probably exotic space-time concepts we haven’t yet thought of…but might be right in front of our eyes. Meditative space bridging might not be ruled out - what is the speed of thought? We are learning the brain, as well as in plants, has some elements of quantum processes…so what might be the speed of tunneling-based, or meditative entanglement? Bio quantum communication?

I agree with Marcy. Life may be relatively common but intelligent life is going to be very, very rare. I think the best we can hope for is to find planets like Earth was two billion years ago with oceans, continents, and only single celled life in the oceans. Such planets would require terraforming but could be transformed into new Earths.

Agreed. Using light or radio waves would be pointless. Quantum entanglement is more logical. But who knows, perhaps ETs have an even more efficient way of communicating through the cosmos without having to signal through time and distance.

Aren't all of you making grand assumptions based only on theory, and that mathematically there has to be other life in the universe. I agree there is life, but I am not going to make assumptions of its intelligence, form, or magnanimous intent. Nor will I assume advancements of any species in the surpassing of the physical bounds of current scientific laws. Just because we can imagine it, doesn't make it so.

Quantum entanglement does not imply faster than light communication. You can still only transmit information at the speed of light at the most.

i was under this understanding:


In the formalism of quantum theory, this effect of measurement happens instantaneously.[8] Repeated experiments have verified that this works even when the measurements are performed more quickly than light could travel between the sites of measurement: there is no slower-than-light influence that can pass between the entangled particles.[9] Recent experiments have shown that this transfer occurs at least 10,000 times faster than the speed of light;[10] this merely establishes a lower limit to the speed — it may actually be instantaneous.[11]

Resonanz- i like where you were going with your comment.

Advanced intelligence would not communicate with Earthlings. We already had visitors, and why would they want to make themselves known to humans? Keep dreaming Marcy.

@ resonanz if your into ufo conspiracies like i am you learn about some weird ideas. For instance supposedly "remote viewing" or psychic seeing is real and the CIA has had a well documented and successful program dating back quite a long time. So our minds are capable of tapping into a matrix of sorts where time and space are all connected and can be moved through freely. The quantum field we are part of can be accessed by our brain, which is a quantum bio computer of sorts.

@ matthew my bro and i looked into remote viewing and we even tried it many times. he was able to do it more often than not, and i wasn't able to do it at all.

Objectively, I'm not saying its real or not, just that it is indeed an interesting subject.

Some people have the knack for remote viewing, some don't.

If I was an alien with advanced tech, I would use neutrinos. They go through matter so when you emit a pencil of neutrinos to transfer data, they go through anything. So you do direct line communication.

Being a scientist and claiming that 300 years in the future the communication medium will be similar to what we use today implies short-sightedness, not to mention lack of historical knowledge: it is enough to recall what was the communication medium 300 years ago.
By the way, there is the No Communication Theorem (proved, already) which states that quantum entanglement cannot be used to send information and faster-than-light speeds.
I think progress in this field can be achieved by radical new trains of thought...

It surprises me, with all of the intellectual posts I have just read and the extrapolation of theories beyond, the classic question seems to have been overlooked. Are we alone in the universe. The communication will come but we need to know if someone is there before we talk to them.

@Mark: Thanks for the support. Can you give me some reference articles on the 10,000 times FTL?

@Alfredo Louro: It is FTL but is not FTL, there is a magic trick going on LOL

So far, string theory can mathematically unify all forces only if consider higher dimensions, and it might not be provable experimentally, unless the measurable quantum entanglement is not a 3 dimension entanglement but higher dimension entanglement, when the 2 photons/electrons are split, in certain conditions, there is created a 4'th(or higher) dimension Entanglement Arc that connects them, the distance between them in our 3 dimensions could be 1 km but the higher dimension arc could be only 1cm (not fixed) and the communication will travel through the entanglement arc at the speed of light but in our 3 dimensions we will perceive it as FTL. The length of the Entanglement Arc will determine the response time.


P.S. This is just my theory, hope the string theory guys would love it LOL

and btw, the quantum entanglement communication will not only be preferred by an advanced civilization due to FTL advantage but also due to the fact that is more secure since might be difficult, if not impossible, to intercept.


P.S. I'm calling it quantum entanglement communication because the quantum communication was already highjacked by spiritual nuts and lunatics that believe a lot of weird things such as: all universe is a big brain, our brains are quantum interconnected, our brains are quantum connected with the universe or a higher power, or other non-sense that can sell books.

However, the feasibility and reliability(arc could be broken by other forces present in that dimension) will still require lots of research so don't expect it that soon. This phenomenon might end up as a way to probe and check if forces in higher dimension behave the same way.

I'm using the term "quantum entanglement communication" because the quantum communication was already highjacked by spiritual nuts and lunatics that believe a lot of weird things such as: all universe is a big brain, our brains are quantum interconnected, our brains are quantum connected with the universe or a higher power, or other non-sense that can sell books.

love the string theory reference. always one of my favorites. i dont currently have any articles on 10k FTL, i just pulled that from the wiki.

Radio/light waves are a pretty primitive method of communication, but if you're broadcasting light waves, use full frequency push pull solid sate hardware to broadcast full frequency AC waves.

You might also consider branching a light beam signal into 2 beams, then shifting one of them 90 degrees out of phase with the other sending them through an analog XNOR gate to double the signal's frequency.

You can forget entirely E.T.s communicating with photons (the electromagnetic spectrum, aka radio to gamma are all photons for the physics challenged Joe Sixpacks out there). Photons travel at a lousey 186,000 miles/second which is unbearably slow and would take 4 years alone for a 1 way trip to even the nearest star's planet(s), Alpha Centauri...let alone other star systems much further than that. The word "communication" implies 2 way commo which means over 8 years round trip if the reply was made instantly or nearly so. Radio/laser transmission from Planet X to space craft: "Hi Mom, happy birthday!" And the faint if even detectable in all the galactic radio interfearance reply 22 years after the initial transmission: "Yer mom died 19 years ago, Joe, sorry 'bout that." Much too long for "walkie talkie" speed or effectiveness. Nope. E.T.s either simply do not communicate (not likely but possibly an option) or they use methods faster than C (light speed for the physics challenged). If their craft can get here from 20 L.Y. away in a few months, say, 100x C, warp speed or whatever you wanna call it, as repeated by folks who supposedly have interface with them, you KNOW they have developed faster than C communication as well. Maser would be much better than laser (microwave amplification by stimulated emissiion of radiation) for microwaves would be absorbed much less by dust and crap in the way from origin to recipient and betcher boots E.T.s would know this (since we cave men with almost no technology comparitively speaking already know it).

I think the project funding for finding E.T. laser and other photon commo scraps is a money sucker only, for pathetic grant moochers, and the daddy warbucks that's funding it is daft and could use the funds for something legit.

Remember, Earth only relatively recently, give it 1 million years at most out of 6+ billion years of existance, has had intelligent life and only in the last century has it had even radio and since the 60s had laser. So given there are X amount of earth like planets in the galaxy, find one that has intelligent life. Not easy. Rare as hen's teeth. I do not count human intelligence as intelligent life when we still use chemical rockets to power space craft at boringly slow speeds, and have no idea what the fundamentals of the universe are, we can only see their manifestations and effects and measure them, but we don't know exactly what they are. Space, time, gravity, magnetism and electrical charge. Don't tell me you know what these five fundamentals are, you do not, you can only say what they do, how to measure them and how to predict their effects. So if we don't fathom that, we are pretty much just animals eating, reproducing and using up O2 and raping resources, not much different from our simian relatives or a parasitic worm, just on a scale that could ruin the planet.
