• 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.

George Dyson Says We May Already Be Controlled by AI

by Brett Tingley                January 18, 2019                  (mysteriousuniverse.org)

• George Dyson – technologist, historian, and son of theoretical physicist Freeman Dyson – has built a career out of studying the history of science and technology. Dyson, and believes current trends point to a future in which the Artificial Intelligence (AI) surely take over. Dyson told Edge.org that for some reason, top computer scientists with the ability to shape our futures want us to become the subservient fodder of a super-intelligent AI hive mind built right into the very fabric of the massive ‘technosphere’ that we’ve constructed around the earth.

• According to Dyson, we’ve already lost control of our most advanced technology and are following the orders prescribed to us by machines. As computers proliferated, the humans providing instructions could no longer keep up with the insatiable appetite of the machines. Codes became self-replicating, and machines began supplying instructions to other machines.

• Think about it. Your social media feeds, search engine results, suggested products on Amazon – all of these are curated for you by intelligent algorithms which study your habits even when you put the phone down for a few scant seconds. Ever notice how ads occasionally appear on your phone for things you’ve been talking about within hearing range of your phone? The machines are listening.

• Could it be possible that we’ve passed the tipping point and are already controlled by AI constructs? When you want to know something, where do you go to look it up? Google has become knowledge. When you want to know what your friends are up to, Facebook has become your social life. As those companies give more and more self-control to their AI networks, Dyson warns that we’ll see human control removed from the equation entirely.

• Technology experts have revealed a startling secret at the heart of AI: we have no idea how the most advanced systems actually do what they do as they become exponentially more and more advanced. Will all-intelligent AI become the new gods of humanity? Or will we respond with an “analog revolution” to counter the out-of-control digital revolution? Dyson, for one, believes so.

[Editors Note]   Numerous insiders, such as David Wilcock and purported SSP experiencers Corey Goode and Jason Rice, warn that humanity’s number one threat is an Artificial Intelligence emanating from another universe that is determined to dominate all biological life forms in this universe. It has overcome many worlds already, and is currently encroaching upon our own increasingly technologically-based planet. But according to Corey Goode, the imminent ‘solar event’ that will transform humanity at a consciousness level will also serve to wipe out the incipient threat of alien Artificial Intelligence, allowing humanity to forge a new spiritual-based experience for our future.  See these two articles by Dr Michael Salla regarding the imminent Solar Flash:  Impending Solar Flash Event Supported by Scientific Studies & Insider Testimony (Jan 7, 2019) and Cosmic Rays as Triggers for Solar Flashes, Earth Core Eruptions & Pole Shifts (Jan 16, 2019)

Despite the frequent warnings of both experts in the field and laymen, we continue to march along towards a future dominated by artificial intelligence constructs. For some reason, those with the ability to shape our futures just really want us to become the subservient Terminator fodder of a superintelligent AI hive mind built right into the very fabric of the technosphere. Are we creating our new overlords? Even worse, have already already created them? Could it be possible that we’ve already passed the tipping point and are already controlled by AI constructs?

It’s possible, according to technologist and historian George Dyson, son of theoretical physicist Freeman Dyson. Dyson has built a career out of studying the history of science and technology, and believes current trends point to a future in which the machines surely take over. To ring in the New Year in the most depressing and hope-crushing way possible, Dyson sat down with Edge.org to discuss the digital revolution and where he sees it heading. According to Dyson, we’ve already lost control of our most advanced technology and are already following the orders prescribed to us by the machines:

                         George Dyson

As computers proliferated, the humans providing instructions could no longer keep up with the insatiable appetite of the machines. Codes became self-replicating, and machines began supplying instructions to other machines. […] There is now more code than ever, but it is increasingly difficult to find anyone who has their hands on the wheel. Individual agency is on the wane. Most of us, most of the time, are following instructions delivered to us by computers rather than the other way around.

Think about it: your social media feeds, search engine results, suggested products on Amazon – all of these are curated for you by intelligent algorithms which study your habits even when you put the phone down for a few scant seconds. Ever notice how ads occasionally appear on your phone for things you’ve been talking about within hearing range of your phone? The machines are listening.
