Warning: This Carl Sagan explaination has caused existential crises.

He explains how 5th dimensional beings perceive 3D creatures, and the implications are so disturbing, I paused it three times.

He said:

A being from the 5th dimension could reach into your locked house, take an object off your kitchen table, and place it in orbit around Jupiter without ever crossing a wall, a door, or the vacuum of space.

People ridiculed when Carl Sagan said this.

But, he was walking through the cleanest piece of geometric logic in modern physics, and most people who watched it never realized what he actually gave them.

The demonstration starts small.

Imagine a flat creature living on a sheet of paper. Its entire universe is length and width. It has no concept of "up" because up doesn't exist in its world. The direction is literally unthinkable to its nervous system.

Now take a three-dimensional apple and push it slowly through the paper.

What does the flat creature see?

A dot appears from nowhere. The dot expands into a circle. The circle grows, shrinks, then collapses back into nothing. The apple was always whole. The flatlander only ever perceived cross-sections of something its dimensions could not contain.

That's the entire trick.

Sagan's move was to rotate the analogy upward and let you feel the vertigo yourself.

You are the flatlander. Your body, your brain, your sensory apparatus evolved to process three spatial dimensions and one directional slice of time.

Anything existing in a higher dimension would pass through your world the same way that apple passed through the paper. As fragments, apparitions, sudden appearances, inexplicable disappearances.

A 4D being could see every organ in your body simultaneously from the outside, the way you can see every room of a dollhouse at once from above.

A 5D being could observe your entire lifetime from every version of you from infant to corpse like a single unmoving sculpture stretched across time.

What's interesting is it's a direct consequence of how dimensions mathematically nest inside one another.

Every dimension has full access to the interior of the one below it. A 3D hand can touch any point inside a 2D square without crossing its edges. A 4D hand could touch any point inside your sealed body without breaking your skin.

Sagan has really handed us a quiet reframe of every "impossible" phenomenon humans have reported for thousands of years like visions, presences, objects moving through walls, beings that seem to know your past and future.

Though his Geometry doesn't confirm any of it. But it removes the argument that such things would violate physics.

For decades, Sweden was known for its inclusive welfare state and its strong voice on human rights.

But recently, the country has come to resemble something very different: an ultra-capitalist haven, with an increasingly tough approach on immigration.

I explained what changed:

The Chinese president stood on a stage in Shanghai and laid out China's entire AI playbook in one speech.

It was his first-ever in-person appearance at the World AI Conference. I went through the whole thing and pulled out everything that matters.

- he opened with his signature maxim that great changes unseen in a century are unfolding across the world.

- he said AI development should not be a solo performance by a single country but a symphony of international cooperation.

- he reaffirmed China's commitment to open source AI in the name of openness and shared benefit.

- he warned against overstretching the concept of national security in AI, where one country puts its own security above everyone else's.

- he said China opposes the emergence of new historical injustices in AI, one of the strongest-worded lines in the speech.

- he pledged 5,000 AI training opportunities for developing countries over the next five years, naming ASEAN, the Arab League, the African Union, CELAC, the SCO, and BRICS.

- he committed to giving 30 countries access to a Chinese AI weather system that provides early disaster warnings.

- a day before the speech, 29 countries signed the agreement creating a new World AI Cooperation Organization headquartered in Shanghai.

strip away the politics and one thing stands out to me. he didn't pitch benchmarks or chatbots. he pitched AI as infrastructure, weather warnings for countries that lose thousands of lives to storms they never saw coming, and training programs for regions the AI boom has skipped.

meanwhile most of the Western AI conversation revolves around which lab ships the next frontier model.

I don't care who wins the race. I care whether the computing power reaches the people who need it.

The full speech is below, and it's worth your time.
