We humans categories living beings based on the Domain, Kingdom, Phylum, Class, Order and Species. Similarly, Civilization in the infinite universe has been divided into five different types. Based on the energy consumption, by Kardashev a Russian scientist. He divided it based on the technical advancement of civilization and how much energy these civilizations harness based on the advancement.
Does life exist outside the Earth?
Yes, just because we can’t contact them doesn’t mean life doesn’t exist in the vast universe. It’s not complex rocket science to grasp. Let me put it in simple words. “What we see is the past, which already happened in the past; our telescopes are only able to see the past images that happened billions and millions of years ago. There is a high chance now that there may be humans or advanced species in the other solar systems in our own Milky Way or other galaxies.
WOW! The signal which we received in the year 1977 is the living proof that there are other civilizations in the vast expanding universe. They must have seen kings ruling the earth or Dinosaurs roaming on earth or newly formed earth. Whatever they have seen they must be searching for life on other planets. They may be humans like us living in other solar systems, our telescopes not able to capture.
Types of Civilizations – Kardashev scale
Type I – Type I civilization will possess the ability to harness the energy present in the planet they are living to the fullest.
Type II – This type has the power to harness the energy of the entire star (Sun is the star type II civilization will be able to use the power of its star which is the main sources of energy in the star system)
Type III- This type has power to control and harness the entire galaxy energy. A far more advanced civilization. They can control black holes and travel by using warm holes.
Originally only three types were defined in the later year they added two more types.
Type IV- There energy control can go beyond the galaxies, and they can harness the energy of entire universe and even manipulate it.
Type V- Much more advanced civilization able to control the energy of the entire universe. In which we are living they may be using the science and advancements which is unknow to us. They can harness energy multiverse level knowledge to manipulate the universe as they feel.
Conclusion
According to me Type IV civilization they are referring to Demi Gods and the finial type is none other than God himself. Now, under what type we human on the earth comes under? None of the types, we fall in Type 0 which is not listed in the scale it takes many more years to reach the type 1. We may reach or may not reach type I.
