Aliens could be observing ancient civilizations on Earth

 A recent study proposes that advanced extraterrestrial beings might be engaged in sightseeing Earth’s significant landmarks.

The research suggests that certain types of highly developed extraterrestrial entities, located at a considerable distance, could potentially identify buildings—but only those from around 3,000 years ago, owing to the time it takes for light to traverse the vastness of the universe.

The peer-reviewed paper, titled “Are we visible to advanced alien civilizations?,” is featured in Acta Astronautica Journal Overview.

Z.N. Osmanov, the author and a Research Affiliate at the Search for Extraterrestrial Intelligence (SETI) institute, posits that by leveraging the universality of the laws of physics, the maximum distance for potential detection is approximately 3,000 light-years.

This implies that extraterrestrial observers might utilize extensive telescopes to discern the architectural marvels of major civilizations from the past, including the Romans, Greeks, and Egyptians.

In addressing the question of our visibility, the study categorizes the technological advancement level of an alien civilization, with a focus on those capable of fully harnessing the energy of their local star.

It is hypothesized that there might be three major technological civilizations: Type-I is an alien society that consumes the total energy incident on a planet from their host star; Type-II is an extraterrestrial civilization utilizing the total energy of the star; and Type-III is an advanced alien society, that consumes the total galactic energy....<<<Read More>>>...

Type V Civilization: The Alien Civilization of Real Gods

 The Kardashev scale is a hypothetical framework for measuring the level of technological advancement of a civilization. It was proposed by Soviet astronomer Nikolai Kardashev in 1964, who classified civilizations into three types based on their energy consumption:

Type I: A civilization that can harness all the energy available on its home planet.
Type II: A civilization that can capture all the energy emitted by its home star.
Type III: A civilization that can control all the energy in its home galaxy.

But some people think that there might be civilizations even more advanced than Type III. They might be able to use all the energy from the entire universe, or even multiple universes. These are called Type IV and Type V civilizations, and they are like real gods.

The difference between Type IV and Type V civilizations is not very clear, as they are both beyond our comprehension. However, one possible way of distinguishing them is based on their relationship with the multiverse.

The multiverse is the idea that there are many different universes, each with its own laws of physics, history, and life forms. Some of these universes might be similar to ours, while others might be very different. Some of them might even have different dimensions, such as time and space....<<<Read More>>>...
