Are We All NPCs?

Let me answer with what I think right away. To me, this is not one of those yes or no questions because it's impossible to tell. Simply put, the theory behind the question is most likely unprovable. Not from the within anyway. 'Simulation Hypothesis' and the phrase 'Non Playable Characters' are concept relatively new, born not that long ago, when digital computing came to be fast enough to produce graphically demanding multi-player games sophisticated enough to hint this question and probability that we might also be inside one of those simulations. And to dispute the question about the nature of reality is quite useless, because everything that surrounds us, no matter how strange we think it is, can also be real and not part of the code. Even if our reality was simulated, its origin would be extremely difficult, if not impossible to prove. By design, nothing inside the simulation could be able to see the lines of the code, only the outcome of its work. In order to

Reality of Double-Slit Experiment

More than two hundred years passed after Thomas Young performed the famous double-slit experiment as a demonstration of the wave behavior of visible light and still it's revelation puzzles our sanity ever since. In short, if we shoot a beam of light at a panel with two small slits (less than a millimeter apart), the photons - elementary particles that light is made of, have to figure out how to get through the slits to radiate out the other side. If they are truly particles, like in macro world, they would project a solid image of two piles on the background wall behind the slits. If they travel similar to the waves, like water does in macro world, the image would resemble a wave-like interference pattern: alternating locations, equidistantly spaced, where particles leave a mark on the wall. Thanks to the outcome of the experiment, we know that light is capable to do both. It always travel in wave like fashion, even if we shoot photons in a row towards slits, one after another. Qua

The Illusion of Time

Since time immemorial, scientific thought did not flow in a straight line. It was full of retrograde motion and ups and downs and many theories were debunked along the way. Take for instant Einstein’s static universe or theory about existence of small planet in the orbit between Mercury and the Sun. On the other hand, illusions originated in our brains were not uncommon either. For the biggest example, we are all aware that weirdly huge Moon right next to the horizon is coming strait from the trickery of our mind. But what about time? It is definitely something we are taking for granted for a vary long time. Could it be both, construct of our own brain and yet based on something more fundamental and still waiting for better understanding? The time from our daily experience, feels very much real. We are living in it's present state and it flows inevitably forward to the uncertain future and thanks to our memories and factual evidence all around us it came from the certain past.

Is Infinity Real?

Sooner or later computation hardware and artificial intelligence algorithms will inevitably reach the point of enough sophistication that creation of a simulation of enormous proportions, for example the size of entire universe, will be effortless. So to speak. These gods-like engineers of such future simulation will indeed face a decision point regarding which degree of limitation to create for their simulated entities or artificial intelligence units in order for them to never reach the point of finding the proof that their world is in fact nothing more than just a series of electrical or optical currents of one inconceivably powerful futuristic computer. If created right, there's no doubt that the inner world of all those hypothetical units would seem to be as real to them as our own very reality to us. So, considering the state of obvious, the question arises by itself - if our own reality is such simulation and we are nothing but AI units within some alien quantum computer, wh

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 refereeing to the life forms only but all matter in the cosmos. For all we know this might not be true within our own macro world alone but also deep below the same goes for particles in the quantum realm as well. The fact is that everything in the universe have 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 meta-stable, the vacuum decay bubble will emerge and consume everything in order to eventually reach the lowest energy state possible. For

Quantum Weirdness

Rarely I've got a chance and real opportunity to revive an old article from the past and to update it to fit better in the present day. Actually, the quantum weirdness is still where it was four years ago - science is not something that changes over night especially with quantum mechanics, so I am not going to update the post with any new physics or breakthroughs. Instead, what 's new and what pushed me to repost today is one extraordinary novel in the field. The book that kept me from sleeping last weekend was "Quantum Space" by Douglas Phillips and in short it is by far, one of the best titles I read this year. It is one of those true sci-fi stories that follows the real science and in this case the weirdness of the quantum world I wrote about in this post and I would add one of those articles I enjoyed the most writing in the history of the blog. But, before couple of my glimpses to the book itself, followed by my warm recommendation and especially if you want to r

Fringe Dream of Virtual Particles

Last night I had a vividly strange science fiction dream. Like with most of my dreams, and dreams in general I guess, it was hard to recall all the details in the morning and this one was no exception, but in the nutshell the scene started with me in some science lab, describing the idea of how to effectively make a tiny hole in the universe. It was pretty simple - I was using four Tesla coils, perfectly positioned in the corners of the large square with edges of about couple of meters long and with a small, battery sized, two metal plates positioned in its center of the square. The experiment was that at the precise moment, Tesla coils fired four filaments of thunder, reaching the center point exactly between two metal plates in the same time, initiating a process that in the end created a tiny breach in the universe that I was describing in the dream as a brane between dimensions and within the void between multiverses. Anyway, in the process, one plate goes from metallic through dar

Rudjer, Nikola, Mihajlo and Milutin

First names. They are of the most importance. Not the middle ones. Not even the last ones, even though with some people family name comes with higher significance, especially if they are part of some important heritage or well-known royalty. Even so, the first names comes, ... well, first. And not by accident. This is how you are remembered for your entire life. This is the word you turn to when you hear somebody is calling around the corner. This is you. With me is the same and while ago I decided to start a thread with first names in titles. First names that are telling connected tales, historically or with any other linked stories. So far there are two in the row: Jules, Isaac, Arthur and Carl and Giordano, Isaac, Albert and Stephen . Behind those names are, according to me, people who gave the biggest push in the worldwide literature of science fiction and science itself. These are people who fit my own interests and fascination and they will be remembered for eternity for their w

Gravis Gravity by Gravitons

Don't take this title too seriously. It's wrong on multiple levels. Grammatically and scientifically. Nonetheless it fits perfectly for this post. As for grammar amiss - I used Latin root word 'Gravis' which means heavy and it is actually perfect adjective for gravity as we perceive it here on Earth. As for scientific issue, the rest of the title might be all wrong. If we glimpse into features of three main natural forces of the universe, it is obvious that they work in more or less the same fashion - they use carriers or elementary particles to mediate the force through the force field. Photon is one of them and it carries electromagnetism while strong and weak force in nucleus respectively are mediated by gluons and w/z bosons and they are all confirmed in experiments. Gravitons suppose to be the same thing for gravitation force, but they are never found and confirmed either directly or consequently. Ever since Einstein we are having second thoughts about whether or

Chasing Ghosts of the Universe

You probably heard that matter is pretty much an empty space. It's true. Everything is made of tiny particles with nucleus in their centers and cloud of electrons orbiting around. If we take Hydrogen (H) for example - the smallest atom with just one proton in nucleus orbiting by just one electron and if we scale the proton to be the basketball size, the orbit of the electron in diameter would be something about 15km. Both, nucleus and electrons are electromagnetically charged, keeping everything in stable equilibrium and also inside nucleus two more fundamental forces - strong and week nuclear interactions are keeping all the matter and energy in line. However, the smallest atom in the Universe is not the smallest, standalone system we know of. According to standard model, all atoms and complex molecules found in nature or artificially produced are made of fundamental particles. Something we cannot cut into smaller pieces. Electron is one of them. But there are more. So far, as far

Nerdiness or Geekdom

I don't think anybody can be characterized with just one word. Not until you actually meet somebody to the core and connect with true friendship. Maybe not even then. People change over time. Slightly, but they do. For instance, when you spot a big bald guy with large tattoo on his neck, wearing a blackish uniform, heavily armed, working as a guard or something with a face on a first glance telling you that you should avoid any conflict with him at any hour, don't judge him just yet. He might be thinking how he hates his job and can't wait to get home and continue reading some poem about early Buddhism or good bestseller novel about love and adventure. For that matter, don't make any assumption about a nice and well dressed guy with great manners and perfect vocabulary. He could be a psychopath perfectly capable of fooling any lie detector driven by his emotionless life. It's simple, you can do what I do, never believe your eyes or first impression. In order to ful

Solar System Weirdness

Do you know how big is our Solar system? I can't be sure of course, but there's a strong possibility that common knowledge about our planetary neighborhood ends with enumerating most of the planets, one dwarf planet and couple of named moons, asteroids and comets. Amazingly, the truth is far, far beyond that and believe it or not, if we include Oort cloud, the Solar system, with us representing its only living residents, is approximately 3 light years in diameter. This is, more or less, equal to 3e+13 kilometers or 30.000.000.000.000 km. The distance about 100 million times bigger than the distance to the Moon. It is tremendously huge and just about one and a half light years shorter than the distance from our Sun to the nearest star! The layout of the solar system*

Time Travel

It's a well known fact that our universe is, as far as we know today, four dimensional space-time continuum with three spacial coordinates and the time playing a role of the fourth one. We are perfectly capable of traveling backwards and forwards within first three spatial coordinates, but is it possible to do the same on the fourth one? I am sure you would agree that it is not too exciting going up or down or left or right but traveling through time could be something special. But, is it possible? Let's explore all the theories, share some stories and read about one connected hoax.

Science of Life in Solar System

There will come one day in the future. Relatively and astronomically speaking, it might come sooner than we think. It could happen way before we realize that there is no turning back. The day when mother Earth will simply say - sorry guys, I have no more energy to sustain this kind of life anymore and when most of biodiversity cocoons on Earth will reach the ultimate hazard and start imploding back into themselves. Air and water pollution will help a lot and not even planet's regular motions will be able to take us into another interglacial cycle. It is as much inevitable as what we are going to do next. We will take a long look toward the stars and say: "Well, we have to do this sooner or later. It's time to leave the Earth. Time to jump into Christopher Columbus's shoes again. And find the new home." But we will not get far. There will be no warp drives, "phasers on stun", robots, AIs or artificial gravity like in Sci-Fi blockbusters and there will b

Solar Eclipse

Moon travels around the Earth in elliptical orbit and logically there are two points in its path where it is closest and farthest from us. Today it was in "perigee-syzygy" of the Earth-Moon-Sun system or simply called "supermoon". Coincidentally, it happens that today it has the power to fully block the sunlight in northern Europe and made the biggest shadow one can do on Earth. In Serbia it only made partial eclipse covering somewhat less than 50% of the Solar disk. These are 12 photos I took in intervals of approximately 10 minutes from eclipse start at 9:40 until it went away around 11:58. The biggest shade was at 10:48. We were pretty lucky today since the nature gave us clear sky with just one stubborn cloud that covered the Sun-Moon kiss around 11AM. Above image is the composition of those 12 photos which I took through our Sky-Watcher telescope with solar filter. I still don't have proper camera or adapter for taking astronomical photos so I used
