Spacetime Quasicrystals: A New Order in the Universe?
For decades, physicists have understood the universe through the lens of crystals – structures with repeating patterns. But what if order didn’t require repetition? That’s the question driving research into quasicrystals, and now, a mind-bending extension of the concept: spacetime quasicrystals. These theoretical structures, existing in the interwoven fabric of space and time, could redefine our understanding of the cosmos.
Beyond Regularity: Understanding Quasicrystals
Traditional crystals, like diamonds or quartz, exhibit a predictable, repeating arrangement of atoms. Think of a bathroom tile floor – the pattern repeats endlessly. Quasicrystals, discovered in the 1980s, break this rule. They possess long-range order, meaning there’s a definite structure, but it doesn’t repeat in a regular pattern. The Penrose tiling, a famous two-dimensional example, illustrates this beautifully. These materials have even been found in nature, within meteorites and the remnants of early atomic bomb tests.
From Space to Spacetime: A Theoretical Leap
Recently, physicists Latham Boyle and Sotirios Mygdalas have taken this concept a step further, proposing the existence of spacetime quasicrystals. Their work, published in January 2026, details the first examples of these theoretical structures. Instead of existing in two or three spatial dimensions, these quasicrystals bridge space and time, creating patterns that unfold across both.
“My feeling was probably it wouldn’t be possible to make a proper spacetime quasicrystal,” says Felix Flicker, a theoretical physicist at the University of Bristol, acknowledging the initial skepticism surrounding the research. However, the findings suggest these structures are not only possible but potentially elegant in their complexity.
Implications for the Universe’s Structure
The implications of spacetime quasicrystals are profound. One intriguing possibility is that they could explain how all ten dimensions, theorized by string theory, are “curled up” while still allowing for the seemingly infinite space and time we experience. The research suggests our universe might be embedded within a higher-dimensional torus, a shape resembling a donut, specifically a (9+1)D torus.
these structures may offer a new perspective on a long-standing puzzle in physics: the discrepancy between the Planck scale (governing gravity), the vacuum energy scale, and the electroweak scale (related to particle masses). The researchers propose that spacetime quasicrystals could help explain the relationship between these scales, currently represented by the equation MPlMvac≈ MEW2.
Time Crystals: A Related, Emerging Field
This research builds on the growing field of time crystals. Unlike ordinary crystals that repeat in space, time crystals exhibit repeating patterns in time. First predicted in 2012 and demonstrated in 2016, these exotic quantum systems are pushing the boundaries of our understanding of matter, and energy.
Future Trends and Research Directions
While spacetime quasicrystals remain theoretical, the research opens up exciting avenues for future exploration. Scientists are now investigating whether these structures could appear naturally, potentially underlying the very fabric of the universe. Further research will focus on:
- Developing more sophisticated mathematical models to describe spacetime quasicrystals.
- Searching for observational evidence of these structures in cosmological data.
- Exploring the potential connection between spacetime quasicrystals and other exotic phenomena, such as dark energy and dark matter.
