Hunt for alien spacecraft begins, as planet-spotting scientist Geoff Marcy gets funding

In the field of planet hunting, Geoff Marcy is a star. After all, the astronomer at the University of California at Berkeley found nearly three-quarters of the first 100 planets discovered outside our solar system. But with the hobbled planet-hunting Kepler telescope having just about reached the end of its useful life and reams of data from the mission still left uninvestigated, Marcy began looking in June for more than just new planets. He's sifting through the data to find alien spacecraft passing in front of distant stars.

He's not kidding - and now he has the funding to do it.

Last fall, the Templeton Foundation, a philanthropic organisation dedicated to investigating what it calls the "big questions" - which, unsurprisingly, include "Are we alone?" - awarded Marcy $US200,000 to pursue his search for alien civilisations.

As far as Marcy, an official NASA researcher for the Kepler mission, is concerned, that question has a clear answer: "The universe is simply too large for there not to be another intelligent civilisation out there. Really, the proper question is: 'How far away is our nearest intelligent neighbour?' They could be 10 light-years, 100 light-years, a million light-years or more. We have no idea."

To answer that question Marcy has begun to sift through the Kepler data and to search the heavens for a galactic laser Internet that might be in use somewhere out there. (More on that in a bit.)

Launched in 2009, Kepler was designed as a four-year mission to detect planets - habitable or otherwise - around distant stars by measuring the dimming of those stars as orbiting bodies pass in front of them. In May, a component of the spacecraft designed to keep it pointing precisely failed, dealing a crushing blow to Marcy and his colleagues who last year convinced NASA to extend funding for the mission into 2016, which Marcy says would have allowed researchers to further refine the number of known Earthlike planets in our galactic neighbourhood.

"It's a heartbreaker," he says. "People are reacting a little bit as if a close family member died. There's this combination of severe depression and confusion, coupled with denial."

Successful so far

Kepler has been wildly successful in its four years. To date, it has found 132 exoplanets - that is, planets outside our solar system - and possibly 3216 more that await confirmation. Researchers have extrapolated from Kepler data that our Milky Way galaxy alone contains at least 100 billion exoplanets, as many planets as there are stars. Still, with the telescope - which is 40 million miles from Earth - having collected data on 150,000 star systems, researchers are only beginning to pick through all the information.

Marcy hopes that hiding within it will be hints about intelligent life abroad. What if, say, the dimming of a star that Kepler observes is caused by something even more fanciful than the passage of extrasolar planets? Something synthetic, perhaps? Marcy admits that even he's not certain what he's looking for.

"I do know that if I saw a star that winked out, then at some point it winked back on again, then winked out for a long, long time and then blinked on again, that that would be so weird," he says. "Obviously that wouldn't constitute the detection of an advanced civilisation yet, but it would at least alert us that follow-up observations are warranted."

Such an irregular pattern might signal the leisurely and unpredictable passage of massive spacecraft in front of the star. But, perhaps more likely, it might indicate the presence of a Dyson sphere, a mainstay of science fiction first proposed by physicist Freeman Dyson in 1960.

The concept is simple. The energy needs of a civilisation a thousand or a million years more advanced than our own would probably be vastly greater than those of even the most profligate earthlings. The greatest source of energy in a solar system is its star, and that energy could be captured by building a massive structure tiled with solar panels enveloping the star - the ultimate green jobs initiative.

Under the second law of thermodynamics, the structure would produce incredible amounts of waste heat in the form of infrared radiation. In September, a Penn State team led by astrophysics professor Jason Wright began searching the sky for just that by combing through data from NASA's Wide-field Infrared Survey Explorer, or WISE. The Penn State work is also being funded by Templeton.

If Dyson spheres pop up in the data, Marcy thinks they would more likely appear as a patchwork of solar panels rather than a solid sphere. Perhaps the dimming of a star would be erratic or quasi-periodic, unlike the regular transit of planets.

To detect such aberrant dimming patterns, Marcy's Templeton grant is funding the salary of a Berkeley student to write software that will chew through the Kepler data."Writing the computer code is not easy," Marcy says. "There's no prescription in any computer science book about how to search for aliens."

Galactic laser internet

The rest of the $200,000 grant is buying Marcy time on the Keck Observatory in Hawaii, the largest telescope in the world, to search for - what else? - a galactic laser internet.

While the movie Contact, based on Carl Sagan's book of the same name, popularised the idea of aliens dozens of light-years away picking up an old telecast of the 1936 Berlin Olympics that was unintentionally transmitted into space, our civilisation has become quieter to any outside observers in recent decades. As our civilisation makes the jump from analog to digital, communication is increasingly carried by fibre-optic cables and relatively weak mobile phone repeaters rather than powerful broadcast transmitters. Rather than spilling out messy radio transmissions, Marcy posits that alien civilisations would use something much more precise and efficient than radio waves to stay connected, and lasers fit the bill. At the Keck Observatory, he hopes to spy an errant beam flashing from a distant star system, an observation that would be strikingly obvious on a spectrum.

This shift to new ways for finding E.T. is in part due to the failure of traditional SETI (Search for Extraterrestrial Intelligence) to pick up radio signals from deep space. Federal funding for SETI projects ended in 1995, but private benefactors have stepped up to support the search for alien radio transmissions, including Microsoft co-founder Paul Allen, who has sunk more than $US30 million into a giant radio telescope array now under construction northeast of San Francisco.

Nevertheless, the silence underscores the question once posed by Nobel prize-winning physicist Enrico Fermi: If intelligent life is common in the galaxy, "where is everybody?"

Marcy admits that this so-called "Fermi paradox" poses a powerful counterargument to the prospect of success for any search for extraterrestrial intelligence. But what if, even if the chances are vanishingly remote, he is successful? More disturbingly, what if (as some respected physicists fear) he finds a Death Star?

MessageToEagle.com - What if someone told you your own thoughts possess the immense power to change your reality?

Is it really possible to alter the present and the future with certain techniques that allow you to re-program your thinking?

There are some scientists, like Dr. Joe Dispenza, D.C who claim that your mind can actually change your reality.

The brain is not static, rigid and fixed. Brain cells are constantly and continually remolded and reorganized by our thoughts and experiences.

"Recent studies in neuroscience have shown we can change our brain just by thinking. The question lies here: What exactly do "you" spend most of your time mentally rehearsing, thinking about and finally demonstrating? Be it the conscious or unconscious fabrication of your thoughts and actions, you are always affirming and reaffirming your neurological self as "you". According to neuroscience, bear in mind that whatever you mentally attend to, without any doubt it is what you are and what you will become," Dr. Joe Dispenza says.

 

 

Dr. Dispenza noticed that humans possess an unconscious addiction to certain emotions, that are either negative or positive. Through his research he learned that emotions condemn a person to repetitive behavior, developing an "addiction" to the combination of specific chemical substances for each emotion that flood the brain with a certain frequency.

 

Eric Davis, Physicist, Explains Why Scientists Won't Discuss Their UFO Interests

For a very long time, the scientific community has been wary of studying UFOs, and the scientists themselves hesitate to talk about their beliefs of unexplained aerial phenomena.

But that attitude is changing, and many scientists are joining the discussion without fear of ridicule.

"UFOs are real phenomena. They are artificial objects under intelligent control. They're definitely the craft of a supremely advanced technology," says physicist Eric Davis, a researcher of light-speed travel.

Davis, a research physicist at the Institute for Advanced Studies in Austin, studies propulsion physics, which he hopes will one day allow humans to travel easily and quickly through our galactic neighborhood.

VIDEO: Eric Davis explains how humans will be able to travel through space at faster-than-light speed.

He's aware of the public perception -- mostly from skeptics and debunkers -- that no legitimate scientists would ever touch the subject of UFOs.

"They're wrong, naive, stubborn, narrow-minded, afraid and fearful. It's a dirty word and a forbidden topic. Science is about open-minded inquiry. You shouldn't be laughing off people. You should show more deference and respect to them ... Scientists need to get back to using the scientific method to study things that are unknown and unusual, and the UFO subject is one of them."

Davis is one of several scientists who are presenting their views this weekend on a variety of UFO-related topics at the 2013 MUFON Symposium in Las Vegas.

The physicist, who recently won an award from the American Institute of Aeronautics and Astronautics for his study, "Faster-Than-Light Space Warps, Status and Next Steps," knows many colleagues who quietly study UFOs.

"There are scientists who are aware of evidence and observational data that is not refutable. It is absolutely corroborated, using forensic techniques and methodology. But they won't come out and publicize that because they fear it. Not the subject -- they fear the backlash from their professional colleagues. The impact on their career might be detrimental and they'd get bad publicity.

"It's not an acceptable, funded line of research. The National Science Foundation does not accept UFOs as a subject for scientific study."

It may come as a surprise that many scientists have been interested in UFOs for decades.

For 20 years, astronomer J. Allen Hynek was the U.S. Air Force scientific consultant on UFOs during its famous Project Blue Book UFO study that ended in 1969.

Watch this 1977 video of Hynek talking about astronomers and UFOs.

Davis believes that the domain for UFO investigations doesn't really belong in the hands of scientists.

"It's the domain of military intelligence," he suggests. "The fact that [unknown] craft are flying around Earth is not a subject for science -- it's a subject for intelligence-gathering, collection and analysis. That's because UFOs are not a natural phenomenon, and that's what science studies.
