QuoteIn the three-dimensional world we live in, there are only two types of particles: "fermions," which repel each other, and "bosons," which like to stick together. A commonly known fermion is the electron, which transports electricity; and a commonly known boson is the photon, which carries light. In the two-dimensional world, however, there is another type of particle, the anyon, which doesn't behave like either a fermion or a boson.In a two-dimensional world, two identical anyons change their wavefunction when they swap places in ways that can't happen in three-dimensional physics:
QuoteAfter decades of exploration in natureâ€™s smallest domains, physicists have finally found evidence that anyons exist. First predicted by theorists in the early 1980s, these particle-like objects only arise in realms confined to two dimensions, and then only under certain circumstances â€" like at temperatures near absolute zero and in the presence of a strong magnetic field.

Quote from: Jason Harvestdancer on December 14, 2020, 10:04:36 PM2D objects in 3D space makes some sense - at least more sense than 3D objects in 2D space.I read in Scientific American several years back that some scientists think that the spacial dimensions didn't all unwind at the same time, that during the early universe it was 1D, then 2D, then 3D. Those same scientists think that in the great voids between galactic clusters the 4th spacial dimension is starting to unwind, creating 4D space.
