Alien civilizations from level 1 to level 7 - We are only at level 0.72


Recommended Posts

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 is hypothetical, and regards energy consumption on a cosmic scale. 


Kardashev's has given rise to numerous scenarios exploring the possibility of more evolved civilizations. These scenarios each question in their own way, defining a civilization: energy sources, technology and the transmission of interstellar messages. 

The purpose of this classification is to guide the search for extraterrestrial civilizations, particularly within SETI, in which Kardashev participated, and this on the assumption that a fraction of the energy used by each type is intended to communicate with other civilizations. 

To make this scale more understandable, they compare the speed of transmission across the galaxy of a volume of information equivalent to a medium-sized library. 

For example: 
A type 2 civilization can send this data by means of a transmission beam emitting for only 100 seconds. A similar amount of information can be sent across intergalactic distances of about ten million light years, with a transmission time of several weeks. 
A type 3 civilization can transmit this same amount of data to the entire observable universe with a transmission time of 3 seconds.

Kardashev believes that it will take humanity 3,200 years to reach Type 2, and 5,800 years to reach Type 3, but physicist and futurist Michio Kaku suggested that, if humans increase their energy consumption at an average rate of 3 percent each year, they may attain Type 1 status in 100–200 years, Type 2 status in a few thousand years, and Type 3 status in 100,000 to a million years. 

A Type I civilization is usually defined as one that can harness all the energy that reaches its home planet from its parent star.

A Type 2 civilization is capable of harnessing the energy radiated by its own star, or example, by means of the successful completion of a Dyson sphere or Matrioshka brain. 

Note 1: A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures a large percentage of its solar power output. 

Note 2: A Matrioshka brain is a hypothetical megastructure of immense computational capacity powered by a Dyson sphere. It is an example of a class-B stellar engine, employing the entire energy output of a star to drive computer systems. 

A Type 3 civilization is in possession of energy at the scale of its own galaxy. Civilizations of this type as having access to power comparable to the luminosity of the entire Milky Way galaxy.

A Type 4 civilization can control or use the entire universe while a Type 5 civilization can control collections of universes as well as there is a Type 6 multidimensional civilization and a Type 7 creator civilization what is discussed in the video below. 

At the current time, humanity has not yet reached Type 1 civilization status, we are only at level 0.72

      Jon Stewart has spent more than 20 years researching the authenticity of a VHS Tape showing an alleged interrogation of a Gray Alien who was captured sometime around 1991. 

      He watched the video soon after its release in 1996 and became intrigued by its realistic depiction of the Gray Alien. 
      Stewart consulted video and animation experts, who did not detect any forgery. Stewart received a list of medical and military personnel directly involved in the interrogation and was able to speak with several of the named individuals. 
      He also learned about a disgruntled group of military insiders associated with the infamous S-4 facility at Area 51 who revealed they were behind the leaked video. 
      Stewart concludes that the tape is authentic and was leaked by an insider called Victor.

      One of the first observations made by NASA’s James Webb Telescope shows a Wolf-Rayet star, named WR 124. The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius. 

      But the James Webb Space Telescope has not only captured a remarkable image of the star WR 124, as the same image also shows a mysterious luminous object in space at a considerable distance of the star WR 124. 

      A closer look reveals that the enormous object resembles what looks like an alien craft in the form of a flying saucer with a rectangular porthole at the front of the craft. Furthermore it looks like there is some kind of rectangular platform underneath the UFO that may have been attached to the craft.  

      Another detail is the object's unique shape which is symmetrical, (see image below) making it more likely that JWST captured an alien spacecraft rather than a celestial body.

      Sean Kirkpatrick, director of the Pentagon’s All-domain Anomaly Resolution Office, wrote in a research titled “Physical Constraints on Unidentified Aerial Phenomena” and co-authored by Abraham Loeb, chairman of Harvard University’s astronomy department that there is a possibility that extraterrestrial motherships and smaller probes may be visiting Earth and other planets in our solar system. 
      The Pentagon is literally talking about the existence of alien motherships that release probes to earth.
      “An alien mothership could potentially be a parent craft that releases many small probes during its close passage to Earth. In their research paper they suggest that 'Oumuamua' is possible such a mothership with probe capabilities. 
      These tiny probes would reach the Earth as the mothership passes by within a fraction of the Earth-Sun separation, just like ‘Oumuamua’ did,” the authors explained. Astronomers would not be able to notice the spray of mini-probes because they do not reflect enough sunlight for existing survey telescopes to notice them. source.
