Imagine that humanity somehow acquires highly credible, empirically grounded information about a civilization that became technological around 3 billion years ago and still exists somewhere between 15,000 and 50,000 light-years away. They are extraordinarily advanced by our standards, but still recognizably bound by physical limits rather than possessing unlimited power or galaxy-spanning control. In fact, one of the deepest implications of this information is that Type III Kardashev civilizations simply do not exist in our universe, at least not yet. Even the oldest surviving species in the galaxy still seems entirely constrained by distance, time, energy, logistics, and survival itself. This civilization just had an impossible, massive head start.

They emerged extremely early in cosmic history, in a region where stars and habitable worlds were much more densely packed than they are around us. Life itself also appears to be extraordinarily common in the universe (just baseline chemistry given enough time). When their original star began dying, they survived because another habitable system existed only around 2 light-years away from them. They migrated there and, intentionally or not, caused the greatest mass extinction event that planet had ever experienced. Entire branches of life disappeared permanently. Some of those native species may already have possessed non-technological intelligence comparable to whales, octopuses, or something beyond either. What matters is that they chose their own survival over coexistence or at least didn't care that much about causing the extinction (they had a choice).

Strangely, though, they are not expansionist in the way science fiction usually imagines ancient civilizations. Over billions of years, they have explored only a few dozen nearby systems, focusing on extending their species but also on extracting resources and studying viable options of terraforming (which seems to be their greatest and most important scientific field). And despite being unimaginably advanced compared to us, they follow an extreme form of non-interventionism. They do not contact civilizations confined to their own solar systems. They do not uplift younger species, and they do not interfere even when another civilization is facing total extinction.

The reason for this silence does not appear to be guilt over the biosphere they destroyed during their ancient migration. According to the information humanity received, at some point in their past they became aware of something else. It was some event, pattern, discovery, or inherited knowledge suggesting that direct contact between civilizations can end catastrophically in ways far worse than ordinary war or conquest. It wasn't necessarily something that happened to them personally; it was possibly something they learned from the remnants of another civilization long gone. Whatever it was, it shaped their entire philosophy permanently. Even when they do interact with civilizations approaching interstellar capability, they avoid physical contact entirely. Diplomacy exists, but only as data exchanged at a distance.

There is also a fascinating ideological detail to them. Because they formed so early after the big bang, survived the death of their own star, and benefited from a chain of statistical luck almost impossible to repeat, they developed a kind of civilizational “chosen people” mentality. It isn't genocidal or openly hostile, but they are deeply, quietly convinced that their survival carries ultimate cosmic significance.

And here is the important part: they do not know humanity exists. We have been technological for barely a century. A civilization that old cannot continuously monitor every single world in the galaxy, and species at our stage are beneath the threshold they care to look for. But now, imagine humanity knows about them on the basis of real and verified knowledge. We know all this information I wrote down here and the fact that they are likely the oldest technological civilisation still alive in the Milky Way.

So, how should we react? Do we transmit a message toward them, knowing they will easily survive long enough to eventually receive it? Or do we deliberately remain silent because civilisations that ancient understand structural dangers about the universe that we cannot even conceptualise yet? Do we accept this "status quo"? Do we just focus on contacting other civilisations closer to us in terms of technology now that we know life is extremely common? Do you think the wise think would be ignoring this "grandfather" figure of the galaxy?

I know this sounds absurdly specific. Yes, I’m aware of that, but just bear with me for a moment.

I know it's already too late, and there is probably no possible solution. But I don't know, there is a part on me that still wants to try. Anyone had any experience like this? Where do I even start? It's too late because it's May... and the ERASMUS would be next year. Is there any other program I can try?

Short spoiler: that strategy caused me to miss out on 99% of social interactions, and I eventually ended up with only a single friend.

I’ve realised that my shyness (likely social anxiety) makes me hyper-aware of everything. Because of this, I function "very fast" when dealing with people socially. I’ve also found that even when I show interest in others by asking questions and being caring, it isn’t enough. Often, people don’t ask me anything in return; they only talk about themselves. But this isn't limited to actual social interactions; I feel nervous even doing ordinary things like walking on the street or being inside a train. I just don't look people in the eye, and I feel they are judging me.

In terms of interests, I feel like I’m fairly "boring" for someone in their 20s. I don't watch sports, I’m not working right now, and I don’t party. I prefer deep conversations and have a few specific hobbies—mostly watching series, YouTube videos, and documentaries about space, science fiction, and politics.

What’s confusing is that I am not always like this. For example, the other day I had a group presentation where I stood up for my teammates and answered the teacher’s questions with genuine confidence. Even though I had a serious face and found it hard to smile, I functioned well. Similarly, with people I’m "class-close" with—those who aren't best friends but who I talk to frequently—I feel much more confident and even have funny moments. I want to know how I can extrapolate this version of myself to other situations, like talking to teachers, meeting strangers, or being at parties. How do I stop feeling so awkward that I become conscious of how I move my lips or deal with the physical tension of a fake smile and lip trembling?

When I’m in a regular class, however, I feel rigid. It’s hard for me to even look around, especially in classes where I don’t know anyone. When I have to speak, I talk way too fast and make mistakes I would never make if I were comfortable. I end up showing a mediocre version of myself and never participate. It just feels like a mess all around.

Does anyone have tips for dealing with this?

When I was a kid, I had my fair share of "bad" moments due to bullying. It wasn’t anything extreme, but being highly sensitive caused me to take everything personally. Eventually, I decided to become as ordinary as possible, so I wouldn't be noticed, hoping to avoid any potential negative outcomes.

Imagine that all of humanity united to make sure that Earth or our solar system "shines" as much as possible for tens of thousands of light-years away (minimum 15k ly). Not necessarily in "brightness", but by manipulating the sun or even exploding thousands of nukes in space. Do you think there's any actual way to achieve this? I know this is outlandish, but I just want an answer.

This study: Earth Detecting Earth: At What Distance Could Earth’s Constellation of Technosignatures Be Detected with Present-day Technology? - IOPscience seems to conclude that we could detect a planet with a similar polluted atmosphere as ours as far as 5 ly away.

For an investigation, I have reached the conclusion that we must be capable of detecting technosignatures from civilisations at a minimum of Type I on the Kardashev scale at distances of at least 15,000 light-years. This premise is based on the assessment that our immediate cosmic "neighbourhood" is likely devoid of other technological actors, suggesting that the nearest instance of industrialisation or advanced engineering exists significantly "further" out. Consequently, our search parameters must bypass local stellar systems and focus on a radius that encompasses a much larger portion of the Milky Way’s volume to have any realistic chance of a successful detection.

I believe that there is a nearly minuscule chance of any contact initiated by others; to anyone 15,000 light-years away, we have been "offline" for the last 15,000 years, just as we were until our industrial revolution began leaking technosignatures a mere two centuries ago. We would only be "lucky" if a civilisation in its own infancy, thousands of years in the past, decided to beam a signal in our general direction that happens to reach us now—perhaps an event like the Wow! Signal—but I believe advanced civilisations eventually conclude that while biosignatures are common, technology is not. They likely focus on detecting far-off technosignatures and ignore planets with simple biological markers, assuming they host only bacteria or plants 90% of the time. While we might find hope in detecting the massive engineering of a powerful, ancient civilisation, my investigation has concluded that Kardashev Type III civilisations are simply not possible. This leaves us in a silent middle ground: planets like ours are undetectable at 15,000 light-years, and the civilisations large enough to be seen at that distance don't exist.

My investigation further suggests that even Dyson spheres might remain hidden at this range unless they are emitting an unmistakable, massive infrared excess, and even then, they might be indistinguishable from natural phenomena to our current sensors. We are still in our technological infancy compared to the majority of detectable civilisations that could exist in our neighbourhood.

Leyendo posts antiguos, veo que Phenomena es uno de los mejores cines de España, al parecer. Ahora bien, necesito una experiencia cinemática top porque es mi género favorito (ciencia ficción) y suelo ver películas así en casa. Voy al cine precisamente para tener la mejor calidad audiovisual posible.

Entiendo que el IMAX de Diagonal no es IMAX 100%, es decir, como los de Londres o EEUU.

Lo único que me empuja hacia Phenomena es que he leído que tiene un "vibe" muy de cine antiguo y eso suena bien. Pero ni idea, ¿Qué me recomendáis?
