It's a brainstorming of all who come to the fans of SETI enthusiasts who liked the Suicide Squad movie: are we all alone in the universe? While science still has to give us an answer to the second part of this riddle, a new paper from British Oxford University philosophers on the possibility of other alien civilizations agrees – and unfortunately they do not believe that it looks too good for ET and her friends.
Her research investigates the so-called Fermi-Paradox, aka the answer to the question "Where are all the others?" Discussion on this topic often includes the Drake Equation, a probabilistic estimate of the number of active, communicative extraterrestrial civilizations in our galaxy based on seven variables. The possible outcomes are an argument that has been raging for decades, leading some researchers to conclude that there is a 53 to 99.6 percent probability of being alone in the galaxy and only a 39 to 85 percent probability of that we are alone in the universe.
"Our article assumes that the likelihood is high," Dr. Anders Sandberg, one of the three authors, told Digital Trends. "Normally, we're talking about one-in-a-million odds and higher, but of course, a probability can be arbitrarily small. People tend to be biased when they put numbers into the Drake equation to roughly estimate how many There are extraterrestrial civilizations out there.
"We point out that in addition to the estimate, one must really appreciate how safe they are: simply multiply them together, ignoring the fact that some of them may have very different values , the result is misleading. We have shown that using either past estimates and using their range as a rough estimate of how insecure we are or trying to sketch what science currently knows and how uncertain it is, the paradox disappears. "
Ultimately, they suggest that even if you are a truly optimistic researcher who thinks there are likely to be many alien civilizations, an honest uncertainty estimate" will force you to admit that there is a pretty big chance we can alone. "
However, Sandberg does not believe that we should stop it." On the contrary, "he said," We should acknowledge that there is a non-trivial chance that everything will be in vain, but how important it is to find out if we are alone ̵
Take a look at the researchers' articles to see if their reasoning convinces you.
