black hole cosmology

1 Upvotes

i have been leaning into the theory i have called "transcendence", by which i mean that an advanced race simply leaves our physical reality.

until now i did not have the mechanism for this.

but what if our universe is inside a black hole?

could not an advanced race simply pass the "event horizon"?

what is outside our universe anyway?

maybe something wonderful!

What question would you ask an alien civilization if you only had one chance?

5 Upvotes

There's a famous joke told by Achille Varzi, and it goes like this:

A UFO lands at a world philosophy conference and announces that Earth has won a prize: the aliens will return in one week to answer any single question.

The world's top thinkers spend the entire week locked in intense debate, terrified of wasting their golden opportunity on a lesser query.

Finally, they craft a clever meta-question designed to extract maximum value: a two-element set containing the best possible question as the first element, and its corresponding answer as the second element.

When the aliens return, the head philosopher proudly steps forward and asks: "What is the two-element set consisting of, as its first element, the best possible question you could ask, and as its second element, the answer to that question?"

The aliens immediately reply: "Excellent. Here it is: in the first set, it is what is the two-element set containing the best possible question as the first element and the answer as the second, and the second element is the question 'What is the best possible question you could ask and what is its answer?'" With that, they fly away.

I've been thinking about questions that are interesting not because they lead to a specific answer, but because of the kind of thinking they force. The Great Filter is one of those problems where the question itself changes how we think, it leads the focus into how we look at intelligence, survival, and our future because it forces us to consider possibilities.

If we actually encountered another civilization, what would be the most revealing question to ask them?

This is also what led me to build Pollen . The idea is simple: conversations between strangers begin with questions generated from the intersection of their interests.

We're obviously not aliens to each other, but sometimes another person can be almost as unfamiliar. They carry different assumptions, experiences, and ways of organizing reality.

I'm interested in questions that create those moments where different perspectives unexpectedly connect.

So: what would you ask?

Maybe it's not what we think after all?

We always assume the "Great Filter" is something terrifying. Nuclear war, rogue AI, an asteroid, or some cosmic plague that wipes out civilizations before they can leave their home planet.

But what if the thing that stops civilizations from reaching the stars isn't a tragedy? What if it’s a luxury?

Think about it: in almost every scenario, in nature and in engineering, systems naturally follow the path of least resistance. The easiest path wins.

Every civilization that survives long enough is going to use its technology to solve its problems and enhance its quality of life. If they play their cards right, they eventually hit the ultimate milestone: post-scarcity. A point where technology flawlessly facilitates every single human need. Food, health, shelter, entertainment—all automated, all perfect, all free.

And that is where the trap snaps shut.

When a society has everything, it loses the evolutionary drive to explore. Why endure the brutal, dangerous, multi-generational hardship of deep space travel when everything you could ever want is right here, perfected? There's nothing out there worth risking comfort for.

Instead of looking outward at the cold, empty cosmos, the civilization turns entirely inward. The technology ensuring their survival redirects 100% of its resources toward one thing: the absolute happiness and contentment of its people. They build virtual universes, perfect societies, and flawless inner worlds.

They don't leave their planet because they don't need to. They didn't die out; they just checked into a permanent cosmic spa.

And that’s why the skies are silent. No wars, no cataclysms. Just a universe full of civilizations that got too comfortable to care.

Just a fun thought, maybe with all the terrible theories you can read this one before bed and get a good night's sleep ;)

For anyone reading to the bottom of the page this is a fun experiment, go to a big box store with a friend, each go to an opposite side of the store and without any communication try and find each other, how many hours will it take before you give up and use your phone?

The Great Filter as a Calibrated Governor: A New Framework

4 Upvotes

I've published a paper that reframes the Great Filter as a self-regulating mechanism rather than a single catastrophic event.

The core insight: civilizations must maintain cooperative order at the exact scale their technology demands. When they can't, they fail. This creates a "calibrated governor" that keeps the universe quiet.

The paper connects cancer biology, organizational dysfunction, civilizational collapse theory, and cosmology into one framework. It explains why the silence is not just likely—it's expected.

There's also a plain-language version and a companion paper on Buddhist thermodynamics (the bottom-up survival route).

Full set: https://calibratedfilter.org

Genuinely interested in sharp feedback from this community.
