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
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  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.
Geoff Marcy will look at 1,000 of Kepler’s extrasolar systems in search of solar arrays that pass in front of
stars and make them wink on and off.
“Through these awards, the program aims to support bold, innovative research with the potential to expand boundaries and
catalyze breakthrough discoveries, as well as inspire students to pursue scientific knowledge and become original,
forward-looking big question thinkers of tomorrow,” said Donald G. York, the Horace B. Horton Professor in Astronomy and
Astrophysics at the University of Chicago, who led the competition.
“Kepler has now discovered over 2,000 new worlds around other stars, most of them smaller than twice the size of Earth,
and many probably having water,” Marcy said. “This flood of nearly Earth-size planets offers the first opportunity for us
humans to hunt for other intelligent species that may have evolved on them.”
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.”
Weird Alien World Shrouded In Extreme Darkness
Found In The Draco Constellation
The Universe is full remarkable wonders that challenge our imagination and TrES-2b is one of them.
To say that TrES-2b is a dark planet is an understatement. Actually, TrES-2b is the darkest exoplanet ever discovered.
This extraordinary, mysterious alien world is blacker than coal! What exactly is causing this extreme darkness remeains unclear.
Countless Earthlike Alien Worlds
That Will Never Be Like Earth
There could be billions of Earthlike planets in the Universe but a great majority of them may have a totally different internal and atmospheric structure.
Building planets in chemically non-solar environments (which are very common in the Universe) may lead to the formation
of strange worlds, very different from the Earth!
Star Trek - A Series That Will Never Die!
Of all science fiction movies and series that have been produced over the years, there is one particular that seems to
become more and more popular - Star Trek!
What exactly is it that makes Star Trek so special? Maybe the best person to answer the question was Gene Roddenberry.
Alien Species Living In The Inner Milky Way Could Be In Danger
Few people doubt there is intelligent alien life in the Milky Way galaxy, but where can we expect to find it?
Astronomers think that while the inner sector of the MIlky Way Galaxy may be the most likely to support habitable worlds.
Unfortunately some of these places are also most dangerous to all life-forms.
When Will Humans Join The Galactic Club?
Most people believe that humans will sooner or later establish open contact with aliens.
When it happens, we might get an invitation to join what scientists and science-fiction writers refer to as the "Galactic Club".
There is also a possibity that advanced extraterrestrial civilizations will not welcome us a new members.
Black Plants Could Exist On Alien Worlds With Two Suns
We have previously seen what auroras might like on alien worlds.
This time we examine how life on planets in binary star systems can evolve.
Earth-like planets with two or three suns would have multiple sources of light that could be used for photosynthesis. This means plants on such worlds could be dark, even completely black.
Photosynthesis, converting sunlight into energy is the basis for the majority of life on Earth.
Black Holes Reveal More Of Their Secrets
Black holes that get deformed, because of other black holes or stars crashing into them, are known to emit a new sort of radiation,
called gravitational waves, which Einstein predicted nearly a hundred years ago.
