Unsealed: Alien Files – The Sun episode 39

Unsealed: Alien Files – The Sun episode 39: UFOs may be visiting the sun and tampering with its power. The sun. It’s an immense powerhouse on a scale that almost defies the imagination. And it’s the source of all life here on Earth. But what if that power was being tampered with? Are UFOs really visiting our Sun?

In April 2011 the FBI declassified decades’ worth of secret government documents that contain thousands of reports of UFO sightings and alien activity. Each episode of this half-hour series tackles one alien case by investigating the previously off-limits government files. The program re-examines key evidence and follows developing leads based on newly released information.

Mass UFO sightings, personal abductions, government cover-ups, and alien news from around the world are some of the topics covered by the show’s panel of specialists, who include journalists, researchers, and radio and TV hosts. After watching an episode of `Unsealed: Alien Files’, you may begin to believe that `we are not alone’.

Dyson sphere

A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to explain how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet’s resources alone. Only a tiny fraction of a star’s energy emissions reaches the surface of any orbiting planet. Building structures encircling a star would enable a civilization to harvest far more energy.

The first contemporary description of the structure was by Olaf Stapledon in his science fiction novel Star Maker (1937), in which he described “every solar system… surrounded by a gauze of light traps, which focused the escaping solar energy for intelligent use.” The concept was later popularized by Freeman Dyson in his 1960 paper “Search for Artificial Stellar Sources of Infrared Radiation.” Dyson speculated that such structures would be the logical consequence of the escalating energy needs of a technological civilization and would be a necessity for its long-term survival. He proposed that searching for such structures could lead to the detection of advanced, intelligent extraterrestrial life. Different types of Dyson spheres and their energy-harvesting ability would correspond to levels of technological advancement on the Kardashev scale.

Kardashev scale

The Kardashev scale is a method of measuring a civilization’s level of technological advancement based on the amount of energy it is able to use. The measure was proposed by Soviet astronomer Nikolai Kardashev in 1964.

The scale has three designated categories.

A Type I civilization, also called a planetary civilization—can use and store all of the energy available on its planet.
Type II civilization, also called a stellar civilization—can use and control energy at the scale of its planetary system.
A Type III civilization, also called a galactic civilization—can control energy at the scale of its entire host galaxy.

There are also 2 extended categories.

A Type IV civilization, also called a universal civilization, can control energy at the scale of its entire host universe.
A Type Ω or Type V civilization, also called a multi-universal civilization, can control energy at the scale of multiple universes, and may be able to create universes.
