A scientist from NASA admitted that we could already visit the aliens. But not so simple

Recently, the Network has information that literally blew up the Internet. NASA researcher Silvano Columbano published a paper entitled “New Assumptions to Guide SETI Research”. The report contains some very controversial statements, but media resources all as one began to repeat: “scientists from NASA say that the Earth could already be visited by aliens”; ” Tiny aliens could visit the Earth.” But, in fact, said the expert of NASA?

Let’s understand.

Let’s start with the fact that Columbano, working in the Department of intelligent systems of NASA space Agency, really admits that aliens could already visit the Earth. But in fact, the document he published is another analysis of the Fermi paradox. In other words, the scientist wonders: where are all the aliens?

In terms of scale, there should be many places in space where complex and intelligent life forms could live – the universe is infinitely vast. If we talk in figures, for example, within the framework of the Kepler program alone, scientists have found 3848 confirmed planets. These include candidates in systems that are about 11.2 billion years old. The age of our native Solar system is only about 4.5 billion years. In other words, there is a possibility that at least one of these very ancient systems has an earth-like planet, whose age is 6 billion years more than our Earth.

Let’s imagine what life can be like on this planet. The determining factor in this issue, according to Columbano, will play time (in our case 6 billion years). The scientist points out that technological evolution on Earth is occurring at such a pace that we are unable to predict what humanity will expect over the next thousand years, let alone 6 billion years.

Columbano’s conclusion: our idea of where aliens might be and what technologies might play a crucial role in their detection is based on four misconceptions. And overcoming these misconceptions will help us finally find extraterrestrial civilizations. A brief description of these misconceptions is provided below.


Interstellar travel is impossible or very unlikely

If we are talking about how far we can travel in the Universe, the answer to this question will be biased for a number of reasons. And the main thing is the limitations of our technology and our understanding of the physical laws of the moment. The farthest where a man could get is to fly around the moon in the 70s. We don’t have the technology to travel faster than the speed of light. We don’t even have nuclear space engines. Bye.

However, the aliens may already have these technologies. So it’s obvious to us to look for things like giant spacecraft with ion engines that can fly past Earth. Colombano insists that our limited resources and imagination should not dictate our understanding of how space/energy and space/time can be controlled.


Radio waves are and will be the main form of communication for thousands and millions of years

So far, we haven’t found a way to travel through space faster than the speed of light, so we’re trying to find intelligent life by relying on methods that allow us to communicate over very long distances. This aspect is one of the reasons why SETI (Institute for the search for alien civilizations) continues to search for radio waves from space.

Even if radio waves, as a way of communication, will exist in the distant future (or they are technologically advanced aliens), it is likely that they will be able to carry much more information than the ways to carry now, says Columbano. In other words, “current, we” simply will not be able to identify them is to separate the communication from the “background noise”. According to the scientist, this form of communication may become obsolete in the future. More advanced civilizations are likely to choose other ways of communicating over long distances, ones we are not even able to imagine yet.


Intelligent civilizations will be based on carbon form

According to the author of the report, this is one of the most important misconceptions. We have long relied on our understanding that life in the Universe is based on certain components, without which it will be impossible. We simply stubbornly ignore the possibility that very different forms of life may exist in the Universe. Our carbon-based ecosystem, Columbano believes, may be just a tiny first step in an ongoing evolution, in which intelligent life forms may emerge that are many times greater than us and yet (or never in principle) carbon-based.

It is very convenient to assume that all life in the Universe could appear in situations similar to the one in which our life appeared in the Solar system. But the probability that the evolution of each organism will take place in the same way and follow the same rules is unlikely. If we proceed from this, our interest and attempts to search for life should go beyond the so-called habitable zone of stars. It is difficult to imagine what life forms will look like living in such conditions, how they will behave and or what methods of communication they will use, but they will not be exactly like us. Even remotely.

In fact, the above aspect can affect everything else in the list. For example, the same technologically advanced non-carbon-based civilizations may have access to interstellar travel because they will not be constrained by the limitations that we ourselves have, such as life expectancy or physical size.
We did not attend and did not attend

When searching for extraterrestrial life, said Columbano, largely ignored the potential relevance of UFO phenomena, mainly due to the fact that the bulk of such messages really is a “fake”, and among society there is a clear lack of interest and skepticism about these events. But instead of this position, the expert believes, scientists should focus on finding real “signals” among all this “noise”.

In the bulk of the” noise “in reports of UFOs may be hidden, though small, but the real” signals ” indicating the phenomena that can not be explained, and therefore, they should not be ignored. If we can agree and accept a new set of assumptions about what forms of higher intelligence or technology we can detect, some of these phenomena may be suitable as concrete examples for these assumptions, or at least encourage deeper analysis and investigation.

What needs to be changed to get things moving?

Columbano cites several proposals that will allow a more “aggressive” approach to the search for extraterrestrial civilizations within the same SETI program.

First, physicists should pay more attention to” speculative physics ” — still based on real theories and evidence, but allowing us to expand the boundaries of our understanding of space-time and energy. At the same time, scientists should more actively involve technical specialists to explore the prospects for the development of certain technologies, especially those related to artificial intelligence, as well as issues related to the relationship between man and machine. In addition, sociologists should be involved in the assistance and discussion, who could, if not explain, at least imagine what societies could emerge within such technologically advanced civilizations and what means of communication these societies could use. Last but not least, it is worth paying more attention to UFO phenomena, really worthy of study in the context of a low signal-to-noise ratio.

What conclusion can be drawn from all this? Given all of this-including the fact that life in space can take completely unfamiliar forms – we are again faced with new questions. How can new approaches, ideas and perceptions of certain probabilities help us to establish contact with extraterrestrial civilizations, quite different from those that we imagined for ages? We also have to understand this, because it is another obstacle to our discoveries.
