MessageToEagle.com - Search of evidence for civilizations advanced enough to have built massive orbiting “solar” power stations continue.

Scientists make and will continuously make attempts to find signatures of cosmic-scale archaeological artifacts, like for example, such as Dyson spheres or Kardashev civilizations.

The detection of intelligence elsewhere in the Universe with interstellar archaeology or SETI would have broad implications for science. Trying to make science fiction a reality, astronomer Geoff Marcy - will go through data from the Kepler space telescope to look for Dyson spheres.

In the meantime, Raphael Bousso will make attempts to probe multiverse theory and look for ways of detecting universes other than our own.

Marcy realized that the Kepler data might also reveal stars with orbiting power stations called Dyson Spheres: megastructures that orbit a star and capture a large proportion of its energy. They were proposed by physicist Freeman Dyson more than 50 years ago as a likely way for advanced civilizations to power their power-hungry societies.

"The Dyson sphere conjecture speculates that a planet could be purposely broken up to form a heat absorbing shield around a star to provide more useful energy.
One fanciful model of a Dyson sphere would be a star enclosed in a shroud of solar-cell calculator chips. A recent whole sky search for Dyson spheres using the database from the IRAS satellite [5] has shown that there are at most only a few lackluster candidates in a region containing a million suns," according to Richard A. Carrigan, Jr., Fermi National Accelerator Laboratory, who is the author of the paper Starry Messages: Searching for Signatures of Interstellar Archaeology.

Marcy’s grant - $200,000 for two years – will also pay for time on the enormous Keck telescopes in Hawaii to take spectra of 1,000 planet-hosting stars in search of laser emissions from advanced civilizations.

“Technological civilizations may communicate with their space probes located throughout the galaxy by using laser beams, either in visible light or infrared light,” he said.

”Laser light is detectable from other civilizations because the power is concentrated into a narrow beam and the light is all at one specific color or frequency. The lasers outshine the host star at the color of the laser.”

Bousso, a professor of physics, is known for his proposal with Joseph Polchinski, a UC Berkeley Ph.D. now at UC Santa Barbara, that string theory implies that the universe is comprised of possibly an infinite number of multiverses, each with its own physical characteristics but operating under the same laws of physics.

Though we are unlikely to be able to visit them or even see them with the largest telescopes – light hasn’t had time to travel that far since the universe began – he is optimistic that it’s possible to find predictions of the hypothesis that can be tested.

“People were initially skeptical of Einstein’s general theory of relativity, but now, decades later, your GPS runs on it and it has led to incredibly profound questions in physics, such as how the universe began and what happens inside a black hole,” Bousso said.

“We are just at the early stages of this multiverse theory, but it is a very serious, plausible proposition that we have to take seriously and test – and try to shoot down as hard as we can.”
