Dyson_Sphere_-_06.jpegThe Dyson Sphere179 visiteOn October 14, 2015, Planet Hunters' citizen scientists discovered unusual light fluctuations of the star KIC 8462852 raising press speculation that a Dyson sphere may have been discovered. However, subsequent analysis showed that the results were consistent with the presence of dust.
In 2024 there was press speculation that potential signs of interstellar Dyson spheres had been discovered.
The seven objects of interest – all located within a thousand light-years of Earth – were M-dwarfs, a class of stars that are smaller and less luminous than the Sun. However, the authors of the findings were careful not to make any overblown claims. Despite this, many media outlets picked up on the story.
Less fantastical explanations included a suggestion that the detected infrared was caused by distant dust-obscured galaxies.MareKromiumGiu 01, 2026

Dyson_Sphere_-_03.jpgThe Dyson Sphere (here: Complex and interconnected Dyson Swarm)167 visiteDyson-style energy collectors around a distant star would absorb and re-radiate energy from the star. The wavelengths of such re-radiated energy may be atypical for the star's spectral type, due to the presence of heavy elements not naturally occurring within the star.
If the percentage of such atypical wavelengths were to be significant, an alien megastructure could be detected at interstellar distances. This could indicate the presence of what has been called a Type II Kardashev civilization.
SETI has looked for such infrared-heavy spectra from solar analogs, as has Fermilab. Fermilab discovered 17 potential "ambiguous" candidates, of which four were in 2006 called "amusing but still questionable". Later searches also resulted in several candidates, all of which remain unconfirmed.MareKromiumGiu 01, 2026

Dyson_Sphere_-_02.jpgThe Dyson Sphere240 visiteSince Dyson's paper, many variant designs involving an artificial structure or series of structures to encompass a star have been proposed in exploratory engineering or described in science fiction, often under the name "Dyson sphere". Fictional depictions often describe a solid shell of matter enclosing a star – an arrangement Dyson himself considered impossible. The sphere he imagined consisted of a loose collection or swarm of objects traveling on independent orbits around the star, an arrangement that has become known as a Dyson Swarm.MareKromiumGiu 01, 2026

Dyson_Sphere_-_00_jpg.jpegThe Dyson Sphere180 visiteA Dyson Sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone. Because only a tiny fraction of a star's energy emissions reaches the surface of any orbiting planet, building structures encircling a star would enable a civilization to harvest far more energy.
The earliest modern imagining of such a structure was by Olaf Stapledon in his science fiction novel Star Maker (1937). The same concept was later used by physicist Freeman Dyson in his 1960 paper "Search for Artificial Stellar Sources of Infrared Radiation". Dyson speculated that such structures would be the logical consequence of the escalating energy needs of a technological civilization and would be a necessity for its long-term survival.

Voyager_1A.jpgFarewell...130 visiteOn April 17, 2'26, engineers at NASAs Jet Propulsion Laboratory (JPL) in Southern California sent commands to shut down an instrument aboard Voyager 1 called the Low-energy Charged Particles experiment, or LECP. The nuclear-powered spacecraft is running low on power, and turning off the LECP is considered the best way to keep humanitys first interstellar explorer going.
The LECP has been operating almost without interruption since Voyager 1 launched in 1977 almost 49 years. It measures low-energy charged particles, including ions, electrons, and cosmic rays originating from our solar system and galaxy. The instrument has provided critical data about the structure of the interstellar medium, detecting pressure fronts and regions of varying particle density in the space beyond our heliosphere. The twin Voyagers are the only spacecraft that are far enough from Earth to provide this information.
Like Voyager 2, Voyager 1 relies on a radioisotope thermoelectric generator, a device that converts heat from decaying plutonium into electricity. Both probes lose about 4 watts of power each year. After almost a half-century in space, power margins have grown razor thin, requiring the team to conserve energy by shutting off heaters and instruments while making sure the spacecraft dont get so cold that their fuel lines freeze.
During a routine, planned roll maneuver on Feb. 27, Voyager 1s power levels fell unexpectedly. Mission engineers knew any additional drop in power could trigger the spacecrafts undervoltage fault protection system, which would shut down components on its own to safeguard the probe, requiring recovery by the flight team a lengthy process that carries its own risks.
The Voyager team needed to act first.
While shutting down a science instrument is not anybodys preference, it is the best option available, said Kareem Badaruddin, Voyager mission manager at JPL. Voyager 1 still has two remaining operating science instruments one that listens to plasma waves and one that measures magnetic fields. They are still working great, sending back data from a region of space no other human-made craft has ever explored. The team remains focused on keeping both Voyagers going for as long as possible.
Far-out plan
The choice of which instrument to turn off next wasnt made in the heat of the moment. Years ago, the Voyager science and engineering teams sat down together and agreed on the order in which they would shut off parts of the spacecraft while ensuring the mission can continue to conduct its unique science. Of the 10 identical sets of instruments that each spacecraft carries, seven have been shut off so far. For Voyager 1, the LECP was next on that list. The team shut off the LECP on Voyager 2 in March 2025.
Because Voyager 1 is more than 15 billion miles (25 billion kilometers) from Earth, the sequence of commands to shut down the instrument will take 23 or so hours to reach the spacecraft, and the shutdown process itself will take about three hours and 15 minutes to complete. One part of the LECP a small motor that spins the sensor in a circle to scan in all directions will remain on. It uses little power (0.5 watts), and keeping it running gives the team the best chance of being able to turn the instrument back on someday if they find extra power.
What comes next
Engineers are confident that shutting down the LECP will give Voyager 1 about a year of breathing room. They are using the time to finalize a more ambitious energy-saving fix for both Voyagers they call the Big Bang, which is designed to further extend Voyager operations. The idea is to swap out a group of powered devices all at once hence the nickname turning some things off and replacing them with lower-power alternatives to keep the spacecraft warm enough to continue gathering science data.
The team will implement the Big Bang on Voyager 2 first, which has a little more power to spare and is closer to Earth, making it the safer test subject. Tests are planned for May and June 2026. If they go well, the team will attempt the same fix on Voyager 1 no sooner than July. If it works, there is even a chance that Voyager 1s LECP could be switched back on.MareKromiumMag 07, 2026

(Fr einige ist Gerechtigkeit die Wahrheit, whrend andere glauben, dass Gerechtigkeit Rache bedeutet.
Da ich nun die Wahrheit kenne und Gerechtigkeit will, werde ich nach Rache streben.
Und Rache soll mein sein)
Als ich ein Kind war, brachte mir mein Vater vor langer Zeit bei, den Himmel zu beobachten und die Namen der Sterne und Sternbilder zu lernen.
Er lehrte mich, das Unendliche ber uns zu lieben und mir viele Fragen zu stellen.
Ich musste das tun, obwohl ich wissen musste, dass ich nie eine Antwort bekommen htte.
Aber ich sollte zuschauen, lernen und meditieren.
Egal, was das Ergebnis all dieser Bemhungen gewesen sein mag.
Jetzt, nachdem viele Jahre vergangen sind, mache ich immer noch das Gleiche.
Wenn ich mich nachts in mein Bett lege, sehe ich die Sterne, verloren in einer nie endenden Dunkelheit.
Wenn ich im Morgengrauen aufwache und mich umschaue und sehe, was ich tun soll, sehe ich nur Leere. Banalitten. Elend. Wahnsinnige Streitigkeiten, die ihren Ursprung in unserer unfassbaren Ignoranz und Dummheit haben. Ich hre albernes Geschwtz, Dialoge voller Gemeinpltze, leerer Versprechungen und offensichtlichen Unsinn.
Dann frage ich mich jeden Tag, was die Welt eigentlich antreibt, und ich verstehe, dass unsere Welt nicht von Glauben, Energie, Schnheit, Liebe oder Empathie und Mitleid angetrieben wird.
Unsere Welt basiert auf Lgen.
Die gleichen Lgen, die dazu fhren, dass wir ein elendes Leben fhren, auf der verzweifelten Suche nach dem, was unserer Meinung nach gut fr uns ist.
Wir glauben, dass alles gut gehen wird und wir am Ende unsere wohlverdiente Belohnung erhalten.
Wir werden schnell, przise, pnktlich, rechtmig und nachsichtig sein.
Dies alles wurde uns beigebracht, was wir zum berleben brauchten und ntzlich waren.
Deshalb glauben wir auch, dass alles, was wir studiert und gelernt haben, die Wahrheit ist.
Und die Wahrheit wird uns frei machen.
Wir glauben an ein endloses Universum, das wie eine Uhr funktioniert. Nur, dass diese Uhr ewig ist. Unvernderlich. Fest.
Wir glauben, dass das Universum nicht vollstndig erklrt werden muss, weil es sich allein dadurch erklrt, dass es existiert und wir es sehen knnen.
Zumindest ein kleiner Teil davon.
Die Bcher erklren dies auf viele Arten. Und diese Erklrungen sind die Wahrheit.
Eine Wahrheit, die uns lebenswert macht.
Aber
Was wre, wenn unsere Lehrer uns belgen wrden?
Und das Gleiche taten unsere Lieben, als sie sagten, dass sie uns liebten?
Mssen wir an die Liebe glauben, nur weil Liebe etwas Ewiges und Endloses ist?
Mssen wir glauben, dass Liebe etwas ist, das alle unsere Hoffnungen, Illusionen, Enttuschungen, Fehler und Fehlverhalten erklren kann?
Was wre, wenn unser Motor, den wir Liebe genannt haben, einfach etwas zutiefst Falsches und Nichtexistentes wre?
Und wenn es wirklich existiert, ist es einfach in seinen Grundlagen falsch und funktioniert tatschlich nicht richtig, indem es uns dazu drngt, Dinge zu tun und an sie zu glauben, die uns nicht wirklich am Herzen liegen und an die wir nicht wirklich glauben?
Was wre, wenn alle unsere Trume, Opfer und guten Taten nur Illusionen wren, die auf einem tiefgreifenden Missverstndnis beruhen?
Eine Fehleinschtzung der Realitt?
Was wre, wenn wir alle von der Liebe in die Irre gefhrt werden, weil die Liebe einfach nicht existiert und wenn sie existiert, dann etwas ist, wovon wir nachts nur trumen, wenn die Decke unserer tiefsten Wahrheiten verschwindet und wir so von der kranken und nackten Realitt umgeben sind?
Die Realitt, dass wir ganz allein sind, ewig verloren in einem Universum, das nur in unseren Gedanken lebt?
In unseren unerreichbaren Trumen?
In unserem falschen und schwindenden Mitleid und Mitgefhl?
Vielleicht in unserem leeren und opportunistischen Glauben?
Was wre, wenn die Wahrheit darin bestnde, dass es berhaupt keine Wahrheit gibt?
Was wre, wenn wir alle unerwnschten Shne einer viel zu anspruchsvollen Mutter und eines schelmischen Vaters wren?
Was wre, wenn nichts wirklich real wre oder zumindest nicht so real wre, wie wir dachten?
Deshalb brauchen wir Lgen.
Wir brauchen sie, um unsere Missetaten und die immer noch ungestrafte intellektuelle Arroganz zu rechtfertigen.
Aber vor allem brauchen wir Lgen, um unsere eigene erbrmliche Existenz zu rechtfertigen, die keinen anderen und weiteren Sinn hat, als andere ihres guten Rechts zu berauben, zu glauben, dass wir zutiefst falsch lagen.
Wir brauchen Lgen, um unsere mangelnde Fhigkeit zu erklren, die Dinge so zu sehen, wie sie wirklich sind, zum Beispiel als nichts.
Das Universum ist leer.
Wie das Paradies und die Hlle: Sie sind alle leer.
So wie wir.
Und jetzt, in meinem hohen Alter, und jetzt, wo alle meine Trnen vergossen und ausgetrocknet sind und jetzt, wo all die Schmerzen, die mein Fleisch geerbt hat, gekommen und gegangen sind, kann ich endlich meine Augen ffnen und mich umschauen.
Aber es gibt nichts zu sehen.
Nichts, wofr es sich zu leben oder zu kmpfen lohnt.
Niemand mehr, den man hassen und lieben kann.
Ich bin allein, in diesem endlosen Nichts, das dieses ganze und nichtexistierende Universum umhllt.
Ich bin allein.
Das Universum existiert nicht.
Und wenn es jemals existierte, ist es jetzt verstorben.
Und das tat ich auch.
Amen.

AuroraTree_Wallace_960.jpgThe Aurorae Tree (Image Credit & Copyright: Alyn Wallace)151 visiteDeath Will Come And Will Have Your Eyea
Death will come and will have your eyes.
This death that accompanies us
From morning to night, sleepless,
Deaf, like an old remorse,
Or an absurd vice.
Your eyes will be a vain word,
A silent cry, a silence.
This is how you see them every morning,
When you bend over yourself alone,
In the mirror.
O dear Hope,
That day we too will know
That you are life and you are nothing.
Death has a gaze for everyone.
Death will come and will have your eyes.
It will be like giving up a vice,
Like seeing in the mirror,
Reemerging, a dead face.
Like listening to a closed lip.
And we will descend, into the whirlpool, silent.
(Cesare Pavese, March 22, 1950)

(Justice, according to some, is Truth, while Others believe that Justice means Vengeance.
Now, since I know the Truth and I want Justice, I will seek for Revenge.
And Revenge shall be mine)
When I was a child, long ago, my Father taught me to watch the Sky, learn the name of the Stars and Constellations.
He taught me to love the Infinite above us and ask myself lots of questions.
I had to do that, even though I had to know that I could have never get any answer. But I was supposed to watch, learn, and meditate. No matter what the outcome of all those efforts might have been.
Now, after many years have come and gone, I still do the same.
When I lay down, in my bed, at night, I see the Stars, lost in a never-ending Darkness.
When I wake up, at dawn, and I look around and what Im supposed to do, I only see emptiness. Banalities. Misery. Insane disputes that have their foundation in our unfathomable ignorance and stupidity.
I hear inane chatters, dialogues full of commonplaces, empty promises, and clear nonsenses.
Then I ask myself, every day, what actually powers the World, and I understand that our World is not powered by Faith, Energy, Beauty, Love or Empathy and Pity.
Our World runs on lies.
The same lies that make us go through miserable and dead-slow days, spent in an often-desperate search of what we believe is good for us.
We believe that everything will work fine and that, in the end, we shall get our well-deserved reward.
We shall be prompt, precise, on time, rightful and forgiving.
This, all this is what we have been taught that we needed and useful to survive.
So, we also believe that everything we have studied and learned, is the Truth.
And the Truth shall make us free.
We believe in an endless Universe that works like a clock. Only that this Clock is eternal. Immutable. Fixed.
We believe that the Universe does not need to be fully explained, because it explains itself just by the fact that it exists, and we can see it.
At least, a small part of it.
The books explain this in many ways.
And those explanations are the Truth.
A Truth that makes us worthy of living.
But
What if our teachers lied to us?
And the same was done by our loved ones, when they said they loved us?
Do we have to believe in Love just because of the fact that Love is something eternal and endless?
Do we have to believe that Love is something fit to explain all our hopes, illusions, disappointments, mistakes, and misconducts?
What if our engine, what we have named Love, is just something deeply false and nonexistent?
And, if it really does exist, is simply wrong in its foundations and is actually malfunctioning, pushing us at doing and believing in things we do not truly care and believe in?
What if all our dreams, and sacrifices, and good actions, are just illusions founded on a profound misunderstanding?
A misperception of Reality?
What if we are all misled by Love because Love simply does not exist and, if it does, it is something we just dream of, at night, when the blanket of our deepest Truths disappears, thus leaving us surrounded by the sick and naked Reality?
The Reality that we are all alone, eternally lost in a Universe that only lives in our minds?
In our unachievable dreams?
In our fake and fading pity and empathy?
In our empty and opportunistic Faith, perhaps?
What if the Truth is that there is no Truth at all?
What if we are all the unwanted sons of a way too demanding Mother and a mischievous Father?
What if nothing is actually real or, at least, not as real as we thought it was?
That is why we need lies.
We need them to justify our misdeeds and still unpunished intellectual arrogance.
But, above all, we need lies to justify our own pathetic existence that has no other and further meaning, but depriving Others from their good right to believe that we were deeply wrong.
We need lies to explain our lack of capacity to see things for what they really are, such as nothing.
The Universe is empty.
Like the Paradise and Hell: they are all empty.
Like us.
And now, in my old age, and now, that all my tears have been shed and dried up, and now, that all the pains that my flesh is heir to have come and gone, I can finally open my eyes and look around.
But there is nothing to see.
Nothing to live or fight for.
Nobody to hate, and nobody to love, anymore.
Im alone, in this endless nothing that wraps the whole and inexistent Universe.
Im alone.
The Universe does not exist.
And, if it ever existed, its now passed away.
And so did I.
Amen.
