The Geometry of the Invisible: An Artist’s Exploration of Gravity and Spacetime
By Conrad Garner
Exploring gravity, fluid dynamics, and the hidden geometry of the universe through an artist's perspective.
The Geometry of the Invisible
An Artist's Perspective on Gravity, Spacetime, and the Fluid Nature of the Universe
I've been thinking about gravity.
Not simply as the invisible force that keeps our feet on the ground or planets orbiting the Sun, but as something far more complex: the behavior of the universe's underlying structure.
As an artist, I naturally visualize things through shape, movement, tension, and distortion. And the more I think about spacetime, the more I imagine it as an infinitely complex, fluid-like mesh.
Something that bends, stretches, ripples, and responds to everything within it.
The Universe as a Mesh
In Adobe Illustrator, a complex gradient mesh is made up of interconnected points and curves. Move one point, and the surrounding geometry responds. Distort an area, and the relationships between neighboring points change.
Now imagine that concept extending throughout the universe.
Not a mesh sitting inside space, but a geometry that represents space and time themselves.
Einstein's theory of general relativity describes gravity as the curvature of spacetime caused by mass and energy. In that sense, gravity isn't simply an invisible rope pulling objects together. It's a consequence of the geometry through which those objects move.
That idea makes much more sense to me when I visualize it.
A Giant Eddy in a Stream
Think about a large rock sitting in a flowing river.
Water moves around it, creating changes in current, pressure, and direction. Depending on the conditions, eddies and vortices form, influencing the water well beyond the rock itself.
The same thing happens when large objects disrupt air currents.
I've started imagining massive celestial objects in a similar way.
What if a rotating black hole could be visualized as an enormous eddy in the geometry of spacetime?
Interestingly, general relativity already describes something resembling part of this picture. It's called frame-dragging, where a rotating mass influences the surrounding spacetime geometry.
That doesn't mean spacetime is literally a liquid or that black holes create ordinary fluid vortices. But the visual relationship fascinates me.
An enormous object influencing the structure around it, with its effects extending far beyond its physical boundaries.
Ripples Across the Universe
Now imagine dropping two stones into a pond.
Each creates ripples that travel outward. Eventually, those ripples overlap, combining and interfering with one another.
Gravitational waves are real disturbances in spacetime, generated by accelerating masses. Colliding black holes can produce waves that travel across the universe at the speed of light.
We have actually detected these waves.
What interests me is the larger visual concept: a universe whose geometry is dynamic rather than static.
A structure constantly responding to motion, mass, and energy.
Not unlike an enormous interconnected web, where a disturbance in one region can propagate outward through the surrounding geometry.
Can the Mesh Be Disrupted?
This is where my curiosity moves beyond established physics.
If spacetime can curve, stretch, and ripple, are there limits to how its geometry can behave?
Imagine twisting or distorting a complex mesh until its geometry becomes increasingly extreme.
In an ordinary physical material, enough stress might cause it to tear or develop structural defects.
But what happens when the structure we're discussing is spacetime itself?
I'm not suggesting that black holes literally rip holes in the universe. General relativity doesn't establish that. In fact, the singularities predicted by classical relativity suggest that our present description becomes incomplete under certain extreme conditions.
Still, the question fascinates me.
Could the most extreme gravitational environments reveal properties of spacetime that remain hidden under ordinary conditions?
Could there be deeper structures or behaviors that our existing models don't fully describe?
Beyond the Visible Dimensions
Another possibility I've been thinking about involves dimensions beyond those we experience.
Some theoretical models propose that gravitational influence could extend through additional spatial dimensions.
This is sometimes described as gravity leaking into another dimension.
But gravity isn't a liquid escaping through a crack. In these models, the word "leaking" describes how gravitational influence might spread through a higher-dimensional geometry.
That distinction matters.
It also raises an interesting question: could gravitational effects originating beyond our familiar dimensions influence what we observe within them?
Scientists have explored ideas along these lines, although no extra spatial dimensions or gravitational leakage have been experimentally confirmed.
And while dark matter is inferred from gravitational observations, there's currently no established evidence that it results from interdimensional gravitational effects.
Still, I find the conceptual possibilities compelling.
Thinking Visually About the Invisible
I don't approach these questions as a physicist.
I approach them as an artist.
My understanding begins with geometry, composition, movement, and the relationships between forms.
A spiderweb under tension.
A complex mesh being distorted.
Air currents moving around a large object.
A giant eddy forming in a stream.
Ripples spreading across a pond.
Each offers a different visual language for thinking about the same underlying mystery.
Of course, analogies have limitations. Spacetime isn't known to possess the viscosity of water, the threads of a spiderweb, or the control points of a digital illustration.
But visual thinking can be a useful starting point for asking questions about things we cannot directly see.
The Geometry of the Invisible
Perhaps what fascinates me most isn't gravity itself, but the possibility that spacetime has deeper properties we haven't yet discovered.
We know that mass and energy influence its geometry. We know that geometry can change. We know that gravitational waves travel through the universe.
But the fundamental nature of spacetime, particularly where gravity meets quantum physics, remains an open question.
I imagine an immense, interconnected, fluid-like geometry, constantly responding to the matter and energy within it.
Not necessarily a literal fluid. Not necessarily a physical web.
But a dynamic system whose geometry determines how the universe behaves.
Maybe the most interesting question isn't what holds the universe together.
Maybe it's what the universe is actually made of, and whether space itself is more dynamic and complex than we can currently comprehend.
That's the image I can't get out of my head.
And sometimes, as an artist, the image comes before the explanation.
