New research suggests that the patterns we see in nature may be just shadows of a hidden reality from higher dimensions. Physicists have found that four-dimensional structures can influence the mechanical and topological properties of quasi-periodic crystals. This discovery confirms that quasicrystals are formed by hidden physics of higher dimensions, and not just random patterns. The study was published in the journal Science, writes Interesting Engineering. A quasiperiodic crystal or quasicrystal is a solid material with an ordered structure that never repeats itself exactly, as happens in ordinary crystals, but follows certain mathematical rules. Quasicrystals were first discovered in 1982 by physicist Dan Shechtman. He proposed that quasicrystals also have a repeating, or periodic, structure, but not in the three-dimensional space where we see it. Instead, the true periodic pattern of quasicrystals exists in higher-dimensional space, such as 4D or beyond. Now, physicists have provided new insights into this four-dimensional aspect of quasicrystals. The scientists exposed the quasicrystal to electromagnetic waves and then studied changes in its topology using near-field scanning optical microscopy and two-photon photoemission electron microscopy. When physicists used these techniques to study the interference patterns of electromagnetic waves on the surface of a quasicrystal, the way those waves moved and interfered with each other revealed hidden fingerprints of the fourth dimension in the quasicrystal’s structure. At first, the patterns looked different, but, amazingly, their topological properties in 2D were identical to the point that they were indistinguishable from each other. The only way to tell them apart was to view the quasicrystal in four dimensions. Physicists have discovered topological patterns in four dimensions that govern the real-space topology of two-dimensional quasicrystals and reveal their internal conservation laws. One of their models of the structure of quasicrystals, which explains their properties, suggests that quasicrystals can be understood as projections of higher-dimensional periodic structures into three-dimensional space. So basically, four-dimensional crystal concepts can explain some of their properties. The study’s authors found something that resonates with the existing model. The physicists noticed that the two surface waves appear different and become identical over a period of attoseconds, or billionths of a billionth of a second. This discovery hints that surface wave patterns in three-dimensional quasicrystals are influenced by hidden four-dimensional periodic structures.
