Do we ever meet aliens? And how are they done? A model developed by Hanson and colleagues gives us a more or less reliable estimate
An object that is worryingly attractive. Their presence in the vastness of space is practically certain Other creatures, The so-called aliens. We don’t trust classic green figures with big heads and big eyes, Scientists and scholars They focus on data and estimates to understand when that could happen The third type is intimate encounter.
In particular, the study, taken from Universe Today, was conducted by an interim analytical team. Led by the project Robin Hanson, An American university professor and economist has been focusing on this issue for some time. Here is some interesting information They have been announced.

Aliens and the Third Type of Intimate Encounter: Evaluations by the Researchers Group
To develop the research model, the team led by Hanson relied on the first hypothesis: An intelligent civilization It is formed by a series of steps Found on earth. Precisely for this reason, researchers have developed a model for estimating the whereabouts of so-called graffiti civilizations. The first parameter describes how 99% of advanced life forms appear In the distant future compared to today. The second parameter is about the so-called Large filter, 9 steps leading to full-scale colonization:
- Livable star system
- Reproductive molecules
- Prokaryotic single cell life
- Eukaryotic single cell life
- Sexual reproduction
- Multicellular life
- Ability to use tools
- Industrial civilization
- Large-scale colonization

The third and last parameter is instead Time and place. As illustrated in the model, there will be the effect of choice leading to advanced alien civilization Expanding to fill the universe. In a passage that leads the aliens to move from a quiet civilization to a quiet civilization. So what is the result? In hundreds of millions of years we could encounter aliens. To get to the level of a quiet civilization, the ratings speak of a period of inclusion 200 million to 2 billion years from today.
