Unthinkable Solutions of Fermi's Paradox

"At some point, the gluons will no longer be able to hold the quarks together, and the hadrons will decay. Which will mean the end of matter in this universe." - Albert Einstein 1

As it seems, in our universe, nothing is made to last. Eventually, everything gets old and dies or changes or decays into something else, and I am not referring to the life forms only but to all matter in the cosmos. For all we know, this might not be true within our own macroworld alone, but also deep below, the same goes for particles in the quantum realm as well. The fact is that everything in the universe has a tendency to achieve the lowest energy state and to finally rest within a stable system, even if that means going through various changes or decays. In the quantum world, this could be true for the Higgs field as well. According to Hawking, if it becomes metastable, the vacuum decay bubble will emerge and consume everything in order to eventually reach the lowest energy state possible. For Higgs field being everywhere in the universe, this would mean instantaneous collapse of the whole universe and it's own ultimate change into a new and ultimately alien environment with a completely new set of laws of physics in the aftermath that could not be as friendly to the living beings as they are today.


But relax, this is just a theory; it might be wrong; nothing like it happened in previous 13.8 billion years (or did it?) and the quote from the beginning is not really formulated by the famous physicist. Well, fictitious Einstein did say it in Phillip P. Peterson's 'Paradox', a remarkable piece of science fiction driven by this scientific premise, but still, it might be something he would say if he were still alive today.

'Paradox' is a relatively new novel series, so I am not going to spoil the content, but to really understand how vacuum decay relates to the well-known Fermi's paradox or to better understand aliens' actions towards Earth and other star systems throughout the universe, I'd warmly recommend the read. As a science fiction fan for years and decades, I could only say that I didn't stumble to the better science fiction in relation to concepts such as Dyson spheres, quantum mechanics, fusion engines, antimatter propulsion, warp drives, the creation of the Big Bang and inflationary space, virtual reality of enormous proportions, wormholes, travel, and communication... The list is going on, and I can only speculate what is inside the third book that has just been released (unfortunately, due to my illiteracy in German, I'll have to wait for the summer and its scheduled translation in English). Anyway, this was one of the rare book series with a sequel even more interesting than the first book, with perfectly connected endings in both of them.


The idea of vacuum decay behind Peterson novels for the solution of Fermi's paradox is indeed new in scientific background, but surely there is more logic we can think of and apply to the absence of aliens, and the idea, more than half a century old, is getting renewed attention in recent years. What I am referring to is the simulation theory and/or holographic principle. It is triggered by the very research of black holes and the information paradox, which states that physical information can be lost and swallowed by black holes despite quantum mechanics postulate that nothing, including information, can ever be lost, only transferred from one form to another. One of the solutions for the paradox I discussed a while ago with the question in the post title 'Are We Holograms?' answered Fermi's paradox perfectly.

However, to get back to science fiction, on several occasions in the past, I mentioned "The Thirteenth Floor", the movie that portrays so far the best story about a simulation of everything in existence. I don't know why, but I never read the backstory about this great film, and especially for this post, I went to check where the script came from in the first place and discovered that it was loosely based on the book called "Simulacron-3", written by Daniel F. Galouye way back in 1964. Needless to say, I downloaded the copy and liked it very, very much. Considering the year and the fact that it was written at the dawn of digital computers, the details and sophistication of the story were amazing. In relation to Fermi's paradox, if we are indeed living in a simulated world created by aliens themselves and we are all nothing more than just a bunch of artificial intelligence characters in the game, then the absence of other intelligent forms becomes clear. Or we will meet them when they become programmed and inserted in the simulation. Anytime now.


Next in line of the fictitious solution for Fermi's paradox on the first glance is not something that much unthinkable. But if we reason about communications over long distances in space, calling the ET and/or receiving a message from aliens from deep space is not as easy as we might think. By using our current technology, that is. The most obvious is the SETI project, which was founded half a century ago based on only monitoring electromagnetic radiation in search of ET broadcasts. After that, many years of looking for the signal from the above failed to find anything so far.

The most interesting and one of the first works of science fiction in this realm was Carl Sagan's 'Contact', in which aliens managed to receive the Earth's earliest TV broadcast 25 light years away, decoded it, and sent it back into SETI's antennas. Unfortunately, even though this looks much more plausible than vacuum decay or giant simulation, it really is not. Engineering and the science behind it are cruel. To broadcast anything at all in the electromagnetic spectrum, the signal must be focused and powerful enough to reach the destination without dissipation of the signal, to avoid the data being embedded in too much noise on the way, or to experience path loss while spreading out over long distances. Our EM broadcasts from Earth are meant for Earth only (or for the Moon on occasion or two in the past), and they are not powerful enough to reach even the closest stars without serious signal loss. To get weak transmissions like that, aliens around Vega might need solar system-wide antennas to detect UHF broadcasts from us. The same goes for SETI on Earth; it is unlikely we will ever get anything that is not narrow, focused, and aimed directly toward us. Nevertheless, ''Contact' will always stay on my physical and digital shelves for being one of the best science fiction films in the history of the genre.


At least for this post, the last and final obstacle with life forms swarming the vast space throughout the universe(s) is ... life itself and its potential limitations. Organic life based on carbon or something else exotic to us could be fragile and short in general. One small asteroid strikes the planet in the Goldilocks zone, and poof... everything dies and resets. Billions of years of evolution go into oblivion in a cosmic second. Even if major extinction events miraculously avoid the intelligent species, they might be destined to destroy themselves at the end of the path. Even more unthinkable scenarios we are still not aware of yet can pop into the equation. One of the obstacles could be that life could exist only in networked scenarios, or, to be precise, it could only work and evolve, more or less, in the form of a giant hive mind in relation to the mother planet. If that's true, there could be a limit in distance for a small number of individuals to leave their world, where they would ultimately lose connection to the hive and die. We never sent anyone or anything to live beyond moon orbit, so if this is true, the border of life could be anywhere beyond that.

I am not sure that Arthur C. Clarke had this in mind when he wrote 'Rendezvous with Rama' back then in 1973. Probably not. However, it was not far from common sense that in this unthinkable scenario, in order to sail toward the stars, the only way that could be done is to build enormous spaceships and giant cities that could carry everybody on the one-way journey. There are countless hazards for that kind of travel, and something along the way might happen to the people who originally populated Rama in the beginning. If we add to the story ultimate laws of physics and issues with limited speed of travel, vast distances between stars, and sparse sources when it comes to little things like food and fuel, 'the hive mind' problem could be another perfect solution to the paradox to consider.


But let's stop here with imagining all potential reasons why we still haven't met ET. If I would like only to spice it up with more unthinkable reasons, it would not be that hard. Just think about the "Zoo Hypothesis", in which we are created and observed by aliens in their science fair experiment, or the theory that we are the first intelligent civilization to emerge so far, or that there is 'The Great Filter' that limits intelligent life species from reaching the potential to dive into stars.

In the end, we could all be wrong. Evolution of species throughout the universe might not be headed toward stars at all. Perhaps we have to reset our minds and look elsewhere, no matter how strange it sounds.

Scientific Copenhagen

Do you have that strange feeling when you are about to visit new city abroad and little afraid of what you would stumble to when it come to simple things? Like how to use metro line or how to buy a bus ticket or how to identify your next destination? Or how to book your flight back to your home? Or how to handle a simple dilemma of should you exchange the money to the local currency or is it wise to put your card in every ATM or any other 'slot' machine on your way?

Hello™ at Microsoft Campus Days, 2014

Ericsson, a Swedish multinational provider of communications technology and services, has the answer for you. And me too. Last week, I took my entire family to the trip to Copenhagen for both, business and pleasure hours in the Danish capital. During my previous visits I didn't have much time for tourism and any off work activity for that matter. So I took a little research this time and Ericsson's "Networked Society City Index" helped a lot. Within the well-developed ICT infrastructure, economy and social development as well as environmental progress, Copenhagen is located in the top five within the NSC index, among 31 well developed worldwide cities. After our visit we left Denmark with a feeling that everything, or most of it, went perfectly smooth and applied IT were extremely helpful, simple and useful. Unified communications (UC), integrated into people's business life from within smart gadgets and laptop computers were also big part of it and I can proudly say that, in a way, I took a part in active development of Rackpeople's* Hello™ for Microsoft® Lync® - UC software that integrates with Microsoft's Lync and Exchange and presents video conferencing within a single click on wide variety of screens and devices. The business part of last week Copenhagen's trip was to visit Microsoft Campus Days where Hello™ had a big feature presentation and successfully presented what it can do in current edition. From developer's point of view I have a good feeling that this project will have long life with plenty of room for more versions in the future especially if Skype and Lync integrate and create space for non-business users as well.

However, Copenhagen, beside business side of the medal has plenty more to offer. History, arts, sport and music events, amusement parks, museums, royal and naval sites, shopping streets and malls, restaurants, walks along the canals, sightseeing from the sea and many more, but this time we chose to glimpse the city's unique scientific side. With seven years old boy in our small family, along with me, being a big fan of science and skeptical society, our stay was really special. If you add a last week's Black Friday hysteria, which brought enormous smile on my wife's face all-day-long, I can safely say that we spent one of those memorable times you never forget.

The Rundetårn, a 17th-century astronomical observatory**

The very first day we went to see Rundetårn, almost 400 years old observatory, built by king Christian IV, after first major success of naked-eye astronomical observation of planetary motion, performed by famous astronomer Tycho Brahe. His incredibly accurate measurement of 6 planets motion at the time, was used by Johannes Kepler after Tycho's death in 1601 and for the first time in astronomy, three laws of planetary motion were established, including the one that all planets in Solar system move in elliptical orbits with the Sun at a focus. Even though, there are still suspicious thoughts about honest relations between Brahe and Kepler and even uncleared circumstances related to Tycho's death (traces of mercury in hairs from his beard was found in 1901 autopsy), these two colorful characters of the early 17th century made crucial contributions to our understanding of the universe, including discovery of the Newton's law of gravity which was direct outcome from Kepler's laws.

Anyway, the Round Tower in the heart of Copenhagen is still active and one of the oldest functioning astronomy observatory. The dome is 6.75 meters high and 6 meters in diameter and contains a refracting telescope with 80–450x magnification with equatorial mount. Without elevator and stairs, walking up and down its unique 209 meters long spiral ramp that spins 7.5 times is something special I never saw before. Not to mention we had opportunity to look through the 'scope with two very friendly astronomers who warmly welcomed us and patiently answered all the questions we had.

Apollo 17's moon rock

Next stop in our astronomy tour was Tycho Brahe Planetarium. It is located not too far away from the observatory and hosts 'The Space Theater' with 1000 square meters dome-shaped screen and seeing a giant 3D Earth rotating in front of you or 30+ meters high mammoths in "Titans of the Ice Age" is the experience you don't want to miss. They also hosted a "A Journey through Space" program and permanent exhibition with meteor specimens and one of the largest moon rocks from Apollo 17 mission (in the above image).

Science is not science if you don't experiment in the lab and to have at least a feeling of what scientists do on daily bases, you have to visit Experimentarium City. Main exhibition, last week was "The Brain", with tons of posts waiting to be explored and played with. Needless to say, my favorite was the game with cool name "Mindball" - in which you have to push the ball only by using brain wave sensors. The more you are relaxed and focused, the more it will get into your control and move in desired direction.

Mindball - moving the ball with brain activity

If you like to have your brain scanned and to see which part is activated when you move fingers or if you want to see really cool optical illusions or to learn more about scientific facts and how stuff works or to play memory games or ... simply to experience a great family time, visiting Experimentarium City is mandatory.

Finally, no trip to Copenhagen would be aloud to have 'scientific' adjective in title without visiting national aquarium and the zoo. Opened last year, Den Blå Planet, National Aquarium Denmark, located near to Copenhagen's airport in Kastrup is something you would need to see to believe. Especially if you came from the continental country like Serbia. Equally interesting was the zoo, who went viral earlier this year when they decided to euthanize Marius, the young giraffe, because of a duty to avoid inbreeding, approved by European Breeding Programme for Giraffes. Right or wrong, it is not mine to say, but we humans are responsible for the health of the animal life and at least it is a good thing that there are scientific organizations that are taking breeding of animal species seriously. Anyway, perhaps the best impression in both wild animals and fish exhibitions, to me were their climate controlled environments - in the zoo their "Tropical section" with jungle climate conditions and in case of the aquarium it's "Amazonian region" with tropical plant life, strange looking fish and lots of piranhas.

The Little Mermaid

Finally, I want to thank all my coworkers at Rackpeople for having a good time on and off the office, especially Lasse who invited us for a visit and opportunity to spend my yearly bonus in Copenhagen. Trips like this are also one great opportunity to learn more about the country and region you are visiting and I mean not just about the sites, history, monuments and other attractions, but also about people, hospitality and friendship. Sometimes, the result is more than you hope for.. Sometimes less. Perhaps the best advice when you are visiting abroad, no matter if you are doing it as a pure tourist or within a business agenda, or both, is to leave high expectations at home. Nevertheless, Copenhagen is one great corner of the world, more than worthwhile to visit and this scientific side I wanted to show in this post is something not many cities in the world can offer.
