Don’t trust the right thing done for the wrong reason. The why of the thing, that’s the foundation.
From Interstellar

I imagine you standing still. Perhaps sitting. You’re still, but reading. Your mind moves. The movement of the mind is called thinking. You are reading what I’ve written; this makes you an observer of a vision. My vision. You’re observing my thought processes, which take the form of blocks of text. And sentences. And words. Reading what another person writes is like stepping inside his head. But now I switch to a question: What’s Flatland, and what’s its connection to Interstellar?

Stay in my vision. Follow me.

Flatland: A Romance of Many Dimensions

In 1884, Edwin Abbott wrote Flatland: A Romance of Many Dimensions. Abbott’s worldview aligns closely with that of another writer, Lewis Carroll: the multidimensionality of space, paradoxes, absurdity as the very fabric of reality. Yet the absurdity in their works is not simple “madness”, it’s a mathematical – or geometrical – paradox. The White Rabbit is a time traveler, and the tunnel Alice plunges into in pursuit of him can be interpreted as a wormhole. But can geometry become a novel?

Unlocking the fourth dimension

I’m explaining this simply, but Abbott’s book is complex. If you have not read it yet, give it a try, you’ll be amazed. Abbott describes the adventures of a Square who lives in a two-dimensional universe. The Square visits a one-dimensional universe called “Lineland”, a zero-dimensional universe called “Pointland”, and a three-dimensional universe called “Spaceland”.

In Three Dimensions, did not a moving Square produce—did not this eye of mine behold it—that blessed Being, a Cube, with eight terminal points? And in Four Dimensions shall not a moving Cube—alas, for Analogy, and alas for the Progress of Truth, if it be not so—shall not, I say, the motion of a divine Cube result in a still more divine Organization with sixteen terminal points?
Edwin A. Abbott, Flatland: A Romance of Many Dimensions

The plot is constructed as an extraordinary mechanism of concentric, yet geometrically incompatible and non-communicating worlds. The Square encounters these realities but cannot fully explain them, especially as he realizes that if these different geometric realities could communicate, they would form a “fourth dimension”. This fourth dimension is precisely the one the Nolans use in the movie Interstellar.

The Others

Both Abbott and the Nolans suggest that perhaps our three-dimensional world is being observed from a higher-dimensional reality where “Others” dwell. Who are these Others? Beings of unknown geometry? Unspecified cosmic intelligences? Ourselves in a future geometric evolution? Perhaps the Others are just thoughts, visions of a mind placed in this higher dimension. I guess this idea ignites in your mind memories of things you have already seen and heard. It also stirs thoughts of God, I hope. I think God smiles when we talk about such things. He knows the distance between us and the truth; He knows it in every moment and at every point of our existence; and for each of us. God is the super-observer of the wave-function of the universe. God sees all possible superpositions. Since He is the only observer who can perceive both space and time simultaneously – and because observation alters the quantum system – He creates reality through observation. Anytime, anywhere. For each smallest particle. His omnipotence is also quantum, at least in my mind.

The information paradox

I came to Abbott’s book and Interstellar while researching white holes for my story Nuclear Bulge. As you know, the core of Interstellar is the black hole Gargantua, depicted as a massive, spinning entity with an accretion disk glowing in its gravitational grip. In the real universe, black holes are the “places” where the laws of physics are pushed to their most extreme limits. In Interstellar, white holes are not mentioned, however, one could think that the wormhole in the film might be connected to a white hole. This connection sides with some theories suggesting that matter falling into a black hole might emerge from a white hole elsewhere in the universe; or even in another universe. Quantum mechanics tells us that information cannot be destroyed, it’s the information paradox. If we imagine that information absorbed by a black hole could reappear from a white hole, the solution to this paradox might involve such a structure. This is the concept I am exploring in my story Nuclear Bulge.

All right, I’d better stop. If you have read this far, it means you have stayed within my vision. A vision that exists in a dimension other than your own. It is an intersection of my existence and yours, our “fourth dimension”. Or maybe not.

Either way, thank you for being here, guys.
