“Gödel’s incompleteness theorems argue that the truth of some mathematical systems are unknowable. Alan Turing extended that idea to computers, showing that there are some algorithms for which it is impossible to know whether a computer can complete the calculations for in a finite amount of time. Now, a team of physicists believe they have extended the concept even further to the physical realm. In a finite 2D crystal lattice of atoms it is known that it is possible to calculate in a finite time the “spectral gap"—the amount of energy between the lowest energy level of the electrons in a material and the next one up. In the new work, Toby Cubitt of University College London and his colleagues appear to have shown that in an infinite 2D lattice the calculation of the spectral gap it is impossible to know if the calculation ends. If true, that means that even if the spectral gap is known for a finite-size lattice, the value could change abruptly with just the addition of a single atom and it is impossible to know when it will do so.” - Physics Today
