= Large extra dimensions
{wiki=Large_extra_dimensions}
Large extra dimensions (LED) is a theoretical concept in physics that suggests the existence of additional spatial dimensions beyond the familiar three (length, width, height). These extra dimensions are proposed to be "large" in the sense that their size can be on the order of millimeters or more, in contrast to traditional extra dimensions predicted by string theory, which are typically compactified and very small, on the order of the Planck length (around \\(10^\{-35\}\\) meters).
