The fundamental structure of the universe may be far stranger than previously imagined. Physicists are exploring a mind-bending concept – “spacetime quasicrystals” – geometric structures that, if they exist, could offer clues to some of cosmology’s deepest mysteries, including the perplexing imbalance between the forces governing the very large and the very small. These aren’t crystals as we typically understand them, but rather patterns woven into the fabric of space and time itself, exhibiting order without the strict repetition found in conventional crystals.
Published January 12, 2026, in the journal arXiv, research by Latham Boyle and Sotirios Mygdalas details the first examples of these theoretical Lorentzian quasicrystals – the spacetime equivalent of the well-known Penrose or Ammann-Beenker tilings. The function builds on the established understanding of quasicrystals in Euclidean space, extending the concept to Minkowski spacetime, which incorporates time as a dimension. This theoretical leap could potentially bridge gaps in our understanding of the universe’s fundamental scales, offering a novel perspective on the relationship between gravity, quantum mechanics, and the elusive nature of dark energy.
What are Quasicrystals and Why Do They Matter?
Quasicrystals, first discovered in the 1980s, are materials that exhibit long-range order but lack the translational symmetry of traditional crystals. Instead of repeating in a predictable pattern, they display quasiperiodicity – a complex, non-repeating arrangement. The famous Penrose tiling, a two-dimensional example, illustrates this concept beautifully. These structures challenge conventional notions of order and symmetry, and their existence has spurred significant research in materials science. As explained by researchers at Washington University in St. Louis, the concept extends to “time crystals,” a novel phase of matter that repeats patterns in time and space as reported on March 12, 2025.
The extension of this concept to spacetime is where things secure truly intriguing. Boyle and Mygdalas demonstrate how these self-similar structures can be generalized from Euclidean space to Minkowski spacetime. Their research outlines key novel features of these spacetime quasicrystals compared to their Euclidean counterparts. The implications are profound, potentially offering a framework for understanding the universe’s architecture at its most fundamental level.
A Universe Embedded in Higher Dimensions?
One particularly speculative, yet compelling, idea emerging from this research is the possibility that our universe is embedded within a higher-dimensional structure. Specifically, the authors suggest our $(3+1)$D universe might be embedded in a $(9+1)$D torus, $T^{9,1}$. This isn’t a recent concept – such toroidal compactifications have previously been identified as yielding the most symmetric configurations of the superstring.
This embedding could potentially explain the “seesaw relationship” between the Planck scale ($M_{rm Pl}$), the vacuum energy scale ($M_{rm vac}$), and the electroweak scale ($M_{rm EW}$). Currently, these scales are vastly different, a discrepancy that has puzzled physicists for decades. The relationship is approximately $M_{rm Pl}M_{rm vac}approx M_{rm EW}^{2}$. The spacetime quasicrystal model offers a potential geometric explanation for this observed imbalance.
Connecting to Existing Theories
The research builds upon existing theoretical frameworks, particularly those related to string theory and high-energy physics. The authors note the connection to previous work on toroidal compactifications of the superstring, suggesting a potential link between these seemingly disparate areas of research. Further investigation is needed to determine the validity of these connections, but the initial findings are promising. The paper, available on arXiv.org, has already sparked considerable discussion within the physics community.
Researchers are also exploring the potential for observing these spacetime quasicrystals in Bose-Einstein condensates, ordered systems in spacetime that aren’t exactly periodic in space and/or time as detailed by the American Physical Society.
What’s Next?
While still highly theoretical, the concept of spacetime quasicrystals represents a significant step forward in our understanding of the universe’s potential structure. Future research will focus on developing more concrete models and exploring potential observational signatures. The challenge lies in finding ways to test these ideas experimentally, a task that will require innovative approaches and cutting-edge technology. The exploration of spacetime quasicrystals opens up a new avenue for investigating the fundamental laws of physics and could ultimately lead to a more complete and unified understanding of the cosmos.
