用与度规变化有关的动力学分岔机制解释了实验观测到的拓扑缺陷的形成，并在1986年定义为Falaco孤子。Falaco孤子是在具有不连续表面的连续介质中由宏观旋转动力学实验产生的拓扑相干结构，例如在游泳池中发现的。Falaco孤子的拓扑结构复制了在所有物理尺度上发现的某些特征，从旋臂星系和宇宙弦到亚微观强子。这个易于重复的实验表明，远离平衡的“静止”热力学态（或孤子）的产生可以全局稳定。Falaco孤子代表了一种解释微观费米面自旋配对机制、旋转玻色-爱因斯坦凝聚体中凹坑涡旋结构的发展、连接膜的弦末端亚微观夸克的禁闭问题以及作为光子的量子化针辐射的范例。
A dynamical bifurcation mechanism related to changes of metric signature is used to explain the formation of topological defects experimentally observed and defined in 1986 as Falaco Solitons. The Falaco Solitons are topologically coherent structures created experi- mentally by a macroscopic rotational dynamics in a continuous media with a discontinuity surface, such as that found in a swimming pool. The topological structure of Falaco Solitons replicates certain features found at all physical scales, from spiral arm galaxies and cosmic strings to submicroscopic hadrons. The easy to replicate experiment indicates that the creation of "stationary" thermodynamic states (or solitons) far from equilibrium can be globally stabilized. The Falaco solitons represent a paradigm for explaining a spin pairing mechanism in the microscopic Fermi surface, the development of dimpled vortex struc- tures in rotating Bose-Einstein Condensates, the confinement problem of sub-microscopic quarks on the end of a string connecting branes, and the quantized needle radiation of as photon in terms of a string connecting two Falaco Soliton dimples located on concentric light cone shells.
