Do we have 'loneliness' in this universe?

According to Newsweek, researchers at Oxford University have concluded that we are the only information-based animal in the universe. The results of the study were published early on arXiv.

According to researchers' calculations, the probability that we do not have "friends" in the Milky Way and in the observed space is 53-99.6% and 39-85% respectively.

The team focused on finding answers to the "Fermi paradox": "If there is another intelligence that exists beyond the Earth, why don't we get any signs from them"?

Accordingly, a multitude of different explanations for the above question were given by those interested in "alien hunting" , one of which is the author of the study, Anders. Sandberg. Anders also hypothesized that it was possible that the aliens were going through a "hibernation" period to wait for the universe to cool down and wait for energy sources to be worth more.

Or simply because aliens have never existed, so we can't find their signs.

The team used the tool to estimate the amount that can be found in the Milky Way. This calculation allows "alien hunters" to enter multiple computational values ​​to make a specific conclusion.

They also want to improve rigor for the calculation by showing the patterns of chemistry and genetics and solving the uncertain events hidden in the operation. Sandberg, in an interview with the Universe Today website, laments: "When we discuss such equations, people will often assume that" this measurement is not absolute, so please treat it as a predictable math "and finally, we only get one result forever only built on conjectures".

However, if only based on the Drake equation and completely ignoring the predictions, it will also bring bad effects. Sandberg adds: " If you ignore all the predictions, the Drake equation will make us too confident in its results. Not only that, the result of the equation is also affected by a part If you're looking for a positive result, it will return a promising result, but if you're a pessimist, you will easily get low results. "

By pointing out a series of uncertainties, the team believes that they can eliminate the "belief" factor from the calculation results. Sandberg asserted that this study is not to point to nonsense in the search for alien creatures, and it is not to assert that it is certain that out there in the distant universe, no longer born. Other objects exist. It only adds emphasis to the proposition: we can be the only wise creature that exists in the universe.
