•  A paper submitted by Tabitha Boyajian, an astronomer at Yale, to the journal Monthly Notices of the Royal Astronomical Society (in 2015) described a particular star named KIC 8462852 orbiting only 1,500 light years from Earth. “… KIC 8462852 (aka “Tabby’s Star”), was observed by the Kepler Space Telescope (image above) to undergo irregularly shaped, aperatic dips in flux down to below the twenty percent level.” “We’d never seen anything like this star. It was really weird. (But the data) checked out.”

• The study mostly focused on two interesting anomalies of the star. The first event was recorded between days 788 and 795 of the Kepler mission and showed a single transit causing a star brightness drop-off of 15 percent. The second event was recorded between days 1510 to 1570 and showed a burst of several transits with a brightness dip of up to 22 percent. The transiting objects have to be extremely big.

• Scientists are now trying to point a radio antenna at KIC 8462852 in order to pick up their television shows to solve the riddle. Meanwhile, a second paper is being drafted around the possibility of the light obstruction being caused a colossal artificial device engineered by advanced aliens.

• Considering that our galaxy has existed for more than 13 billion years, it’s not hard to imagine that an alien civilization may be out there, possessing technology that allows them to build megastructures around stars. Jason Wright, a fellow astronomer at Penn State said, “This looked like something you would expect an alien civilization to build.” Researchers are hypothesizing the possibility of a mega-engineered project created by a Type 2 alien civilization on the Kardashev scale. With a vast shell or series of rings surrounding a star, a Dyson sphere-like structure could use all the available energy radiating from a star.

 

Besides Kepler’s ability of finding small, rocky worlds orbiting distant stars, it can also detect different space phenomenon like stellar flares, star spots and dusty planetary rings.

This time however, Kepler detected the signal of a supposed vast artificial structure orbiting a star only 1,500 light years away from Earth.

After finishing all plausible explanations, scientists now believe that this complex structure might be an artificial construction made by an advanced alien civilization way up on the Kardashev scale of comparison.

This megastructure works like a supersized solar array orbiting around its host star, stocking the energy and sending it back to the source. The size of the structure is so grand that it’s blocking a considerable fraction of starlight as it spins around its host.

Normally all the exoplanets discovered by Kepler have a typical planet-shape, meaning they are round. This time however, the telescope detected something that isn’t round and behaves unnatural.

A paper has been submitted to the journal Monthly Notices of the Royal Astronomical Society in which a particular star named KIC 8462852 is described.

OVER THE DURATION OF THE KEPLER MISSION, KIC 8462852 WAS OBSERVED TO UNDERGO IRREGULARY SHAPED, APERIODIC DIPS IN FLUX DOWN TO BELOW THE TWENTY PERCENT LEVEL.

WE’D NEVER SEEN ANYTHING LIKE THIS STAR, IT WAS REALLY WEIRD. WE THOUGHT IT MIGHT BE BAD DATA OR MOVEMENT ON THE SPACECRAFT, BUT EVERYTHING CHECKED OUT. – TABETHA BOYAJIAN, RESEARCHER AT YALE UNIVERSITY

What Is a Dyson Sphere?

Listen to “E65 8-12-19 What Is a Dyson Sphere?” on Spreaker.

• In 1960, British-American theoretical physicist Freeman Dyson theorized that as an intelligent alien species’ population increased by 1% per year, their energy needs would grow exponentially becoming a trillion times larger in just 3,000 years. After developing and saturating the local moons and planets in their solar system, they may embark on a longer-term solution: The Dyson sphere.

• A Dyson sphere is a structure with platforms orbiting in tight formation that surrounds and encloses a larger celestial body, such as a gas giant planet like Jupiter or the system’s star itself, like a shell. Such an artificial structure would offer plenty of living space and energy production, drawing from the gas planet or star’s radiation. But as the Dyson sphere absorbed radiation, thereby dimming the planet from an outside observer’s perspective, Dyson theorized that the structure would need to re-radiate this energy through infrared wavelengths to avoid melting the structure itself. Therefore, a Dyson sphere would emit a bright signature in the infrared spectrum while being invisible to the human eye.

• This infrared radiation is considered a type of ‘technosignature’ that astronomers can use to detect an advanced civilization. Since the 1960’s, researchers have scanned infrared maps of the night sky in hopes of spotting a Dyson sphere, without success. But in 2015, Yale University astronomer Tabetha Boyajian did find a distant star that dimmed and flickered. Astronomers speculated that “Tabby’s Star” could be a partially built Dyson sphere. Because other astronomical experiments could not find other technosignatures from the star, scientists now think the object’s light patterns have some kind of non-alien explanation.

• In 1937, Olaf Stapledon first described a “gauze of light traps” surrounding a star system to utilize its solar energy in his novel “Star Maker”. Freeman Dyson acknowledged that this sparked his concept of a Dyson sphere. In 1992, a Dyson sphere was depicted in an episode of “Star Trek: The Next Generation”.

 

A Dyson sphere is a theoretical mega-engineering project that encircles a star with platforms orbiting in tight formation. It is the ultimate solution for living space and energy production, providing its creators ample surface area for habitation and the ability to capture every bit of solar radiation emanating from their central star.

Why build a Dyson sphere?

          Freeman Dyson

Why would anyone construct such a bizarre monstrosity? According to British-American theoretical physicist Freeman Dyson, who first speculated about these putative structures in 1960, an intelligent alien species might consider the undertaking after settling on some moons and planets in their local stellar neighborhood. As their population increased, these extraterrestrials would start to consume ever-greater amounts of energy.

Assuming this alien society’s populace and industry grew at a modest 1% per year, Dyson’s calculations suggested that the aliens’ area and energy needs would grow exponentially, becoming a trillion times larger in just 3,000 years. Should their solar system contain a Jupiter-size body, the species’ engineers could try to figure out how to take the planet apart and spread its mass in a spherical shell.

By building structures at twice the Earth-sun distance, the material would be sufficient to construct a huge number of orbiting platforms 6 to 10 feet (2 to 3 meters) thick, allowing the aliens to live on their star-facing surface. “A shell of this thickness could be made comfortably habitable, and could contain all the machinery required for exploiting the solar radiation falling onto it from the inside,” Dyson wrote.

But after absorbing and exploiting the solar energy, the structure would eventually have to reradiate the energy or else it would build up, causing the sphere to eventually melt, according to Dyson. This means that, to a distant observer, the light of a star wrapped in a Dyson sphere might appear dimmed or even entirely darkened — depending on how dense the orbiting platforms were — while glowing curiously bright in infrared wavelengths that aren’t visible to the naked eye.

Could a Dyson Sphere Harness the Full Power of the Sun?

by Seeker                  February 24, 2019                   (seeker.com)

• Physicist Freeman Dyson popularized the concept of a structure soaking up 100 % of a star’s (like our Sun) and converting it into useful energy, known as a Dyson Sphere. Dyson claimed that looking for signs of massive structures capturing the power of a host star in distant solar systems could lead us to advanced extraterrestrial civilizations.

• Some believe that aliens might already be using a Dyson Sphere on a mysterious dimming star known as Tabby’s star, theorizing that the dimming is a sign of a structure surrounding the star. Other astronomers say that the dimming is likely just caused by dust.

• But astro-engineers say that a Sun-encircling sphere would be impractical, as the environmental and gravitational stresses of a solid structure around the Sun would certainly destroy the shell, even if we had the materials needed to do it. They suggest that the answer may be a ‘Dyson Swarm’ – a large number of advanced solar panels orbiting the Sun, capturing its light from all directions, and continuously transmitting the energy back to Earth.

• Futurists say building a Dyson Swarm would require extreme measures like mining Mercury for materials – eventually destroying that planet. But a successfully implemented Dyson Swarm could extend humanity’s survival in the solar system and provide the power needed to colonize other planets.

 

In a thought experiment, Physicist Freeman Dyson popularized the concept of a structure that could trap 100 percent of a star’s energy. Dyson claimed that advanced civilizations or extraterrestrials might use massive structures to capture the power of their host star. He said that looking for signs of these structures would lead us to other lifeforms. This concept inspired what later became known as a Dyson Sphere – a hypothetical megastructure that would surround the Sun, soaking up its light and converting it into useful energy.

Today, there are a few different Dyson inspired designs. The classic Dyson Shell, for instance, is often portrayed in sci-fi works. The solid structure, the size of a planetary orbit, contains solar habitats, each powered by their host star’s light. But this megastructure would be impossible for humanity to pull off due to the fact that the materials needed to build it don’t exist. On top of that, environmental and gravitational stresses of the Sun would destroy the shell.

Instead, some astro engineers believe a Dyson Swarm is the most practical design for our solar system. This concept would require the construction of an army of advanced solar panels which would orbit the Sun, capturing its light from all directions. The solar panels would collect the Sun’s radiation and continuously transmit the energy wirelessly back to Earth. Still, futurists say building a Dyson Swarm would require extreme measures like mining Mercury for materials – eventually destroying the planet. But if we manage to successfully create a sun sucking megastructure, it will extend humanity’s survival in the solar system and provide the power needed to colonize other planets. Considering all the advanced technology needed to make this happen though, it will be a very long time until any sort of Dyson Sphere takes the leap from science fiction to reality.

But, like Freeman Dyson, some people believe that aliens might already be using Dyson Sphere-like structures. And they point to a mysterious dimming star – known as Tabby’s Star – as potential evidence. Believers say that the dimming is a sign of a structure surrounding the star. While many astronomers say that the dimming is likely just caused by dust. But in the far-fetched chance that there is an advanced civilization out there soaking up all the energy in the universe, let’s just hope that they’ll use their power for good, not evil.
