Clocks might be far more fundamental to physics than we ever realized.
A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could all be literally a matter of time. Three dimensions of time, in fact.
The basic idea of 3D time isn’t new. But University of Alaska geophysicist Gunther Kletetschka says his mathematical framework is the first to reproduce known properties of the Universe, making it a somewhat serious contender for uniting physics under one consistent model.
“Earlier 3D time proposals were primarily mathematical constructs without these concrete experimental connections,” says Kletetschka.

“My work transforms the concept from an interesting mathematical possibility into a physically testable theory with multiple independent verification channels.”
Something is wrong with our current models of reality. While quantum mechanics and general relativity both explain our Universe to a degree that’s uncannily accurate, each emerges from fundamentally distinct grounds – one granular and random, the other seamless and immutable.
These irreconcilable starting points make it a challenge to construct a single, all-ruling theory of physics that explains gravity in the same way as it does the other three forces. Not that theorists haven’t tried.
Kletetschka proposes a complete rethink on the basics, pulling back the fabric of space-time itself to come up with a new bedrock to base reality on.
While we use the word time to describe virtually any series of events, there’s a clear contrast in scale that extends from the near-instantaneous flitting of quantum particles to the eons of cosmic growth stretching into eternity.
On the cosmic end, time can be relative, distorting in relation to mass and acceleration. Up close, time is undecided, equally capable of looking to the past as it does to the future. And drifting in the middle is an existence as boringly predictable as tomorrow’s sunrise.
Separating these scales into their own dimensions provides us with three paths to follow, each marching to its own beat at right angles to the others.
By embedding these timelines in mathematics that preserves cause and effect, it’s possible to link all three dimensions in a way that could explain everything from how fundamental particles pop up in quantum fields, to why we can’t experience quantum weirdness, to the expanding boundaries of the Universe itself.
“These three time dimensions are the primary fabric of everything, like the canvas of a painting,” says Kletetschka.
“Space still exists with its three dimensions, but it’s more like the paint on the canvas rather than the canvas itself.”

Importantly, the framework precisely reproduces known masses of a number of particles, such as top quarks, muons, and electrons, and volunteers predictions for the unknown masses of neutrinos and subtle influences on the speeds of gravitational waves.
That means the theory could receive support from future experiments, and potentially contribute to a more united approach to physics as a whole.
“The path to unification might require fundamentally reconsidering the nature of physical reality itself,” says Kletetschka.
