Hypercivilizations and the ancient astronaut hypothesis
The A̳n̳c̳i̳e̳n̳t̳ astronaut hypothesis suggests that ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ beings visited Earth in A̳n̳c̳i̳e̳n̳t̳ times and aided in the development of A̳n̳c̳i̳e̳n̳t̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s. Some believe that these c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s, such as the Egyptian, Mayan, and Inca, were built with the help of advanced technology handed down to them by ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ visitors.
The idea that beings from other planets have visited Earth and left their mark on human History is appealing to many people. This hypothesis has become popular in recent years thanks to the spread of television programs and movies that present it as a possible explanation for some of the mysteries of History.
One of the ideas related to the A̳n̳c̳i̳e̳n̳t̳ astronaut hypothesis is that of hyperc̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s. This is the theory that extremely advanced c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s may exist in the universe that have been able to colonize and control large portions of space. These hyperc̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s would have Technology so advanced that it would be indistinguishable to us from magic.
The idea of hyperc̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s was first proposed by the Russian theoretical physicist Nikolai Kardashev in 1964. Kardashev proposed a scale of types of c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s based on a society\’s degree of energy harnessing. According to this scale, a c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳ of type:
1 would be able to harness all the energy available on its planet, a
Type 2 c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳ would be able to harness all the energy of its star.
And a type 3 c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳ would be able to harness all the energy in its galaxy.
The A̳n̳c̳i̳e̳n̳t̳ astronaut hypothesis suggests that some of Earth\’s A̳n̳c̳i̳e̳n̳t̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s may have been influenced by type 2 or 3 beings. These beings would have shared their technology with Earth\’s A̳n̳c̳i̳e̳n̳t̳ inhabitants and assisted in the construction of its great monuments. and cities.
Since we started exploring space, we have discovered a large number of planets in our galaxy. Although most of them are inhospitable, some have features that suggest they could support life. Here are some examples of planets that have been discovered so far that might have the conditions necessary for life:
Kepler-452b: This planet orbits around a star similar to the Sun, at a distance that allows the presence of liquid water on its surface. It also has a similar mass and radius to Earth, making it one of the closest planets to our own home yet discovered.
TRAPPIST-1e: This planet orbits an ultracool dw̳a̳r̳f star, which means it receives much less radiation than Earth. This could make it easier for liquid water to sit on its surface. Furthermore, TRAPPIST-1e is within its star\’s habitable zone, making it a promising candidate for life.
LHS 1140b: This planet orbits a red dw̳a̳r̳f star, but it is in that star\’s habitable zone. Also, LHS 1140b is larger than Earth, which could mean that it has a denser atmosphere capable of holding liquid water on its surface.
Proxima Centauri b: This planet orbits around the closest star to the Solar System, which makes it one of the most interesting targets for the search for ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ life. Although its star is a red dw̳a̳r̳f and Proxima Centauri b receives much more radiation than Earth, scientists believe there could still be liquid water on its surface.
Gliese 667Cc: This planet orbits around a red dw̳a̳r̳f star and is in that star\’s habitable zone. Plus, it\’s one of the closest planets to Earth ever found, which means it would be relatively easy to send a mission to explore it up close.
So even if we don\’t have conclusive evidence, that possibility exists.
