Large scale structure

At scales of hundreds of millions of light-years or more, the distribution of cosmic matter presents a picture of fibrous structures composed of galaxy clusters, superclusters, and huge voids intertwined, like countless bubbles densely overlapping together, which is the large-scale structure of the universe.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Large scale structure, in physical cosmology, refers to the distribution characteristics of mass and light in the observable universe over a large range (typically billions of light-years). Sky surveys and investigations and depictions of various wavelengths of electromagnetic radiation, particularly 21 centimeter radiation, have revealed many aspects and characteristics of the structure of the universe. The organization of the structure seems to follow a hierarchical model, with superclusters and Cosmic Filaments as the topmost scales. Even the largest ones seem to have no continuous structure, which refers to the phenomenon of 'end of greatness'. Display information such as dark matter density, gas density, gas velocity field, stellar mass density, gas temperature, gas metallicity, shock Mach number, magnetic field strength, X-ray luminosity, etc. of the same large-scale structure at the same time. Enable visitors to intuitively experience the gods of the universe.
