01 / Overview

There are various speculations and hypotheses about the origin of the universe, among which the most widely accepted is the Big Bang theory. It proposes that the universe began about 13.8 billion years ago in an extremely hot and dense singularity, and then underwent rapid expansion, forming the observed structure of the universe today. Other hypotheses include the "eternal expansion theory of the universe," "cosmic regression theory," "constant universe theory," "string theory," and "membrane universe theory. These hypotheses attempt to explain the birth, evolution, and ultimate fate of the universe, and are still a hot topic in modern physics and cosmology research.

02 / How visitors use it

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.

03 / The science behind it

The Big Bang theory: The universe started from a singularity with extremely high temperature and density about 13.8 billion years ago, and gradually formed the current structure of the universe through rapid expansion and cooling. The Big Bang theory is currently the most mainstream viewpoint in the field of astronomy. The cosmic microwave background radiation and redshift are key observational evidence supporting the Big Bang theory. Membrane Universe Theory: The membrane universe theory holds that our universe is a three-dimensional membrane embedded in a higher dimensional "bulk" universe, and the "Big Bang" is the result of two membranes colliding in high-dimensional space. Quantum fluctuation theory: Quantum fluctuation theory holds that the vacuum quantum fluctuations in the early universe caused small energy disturbances, which were amplified by inflation to form large-scale structures such as galaxies, becoming a key mechanism for the origin of the universe. Boundless Theory: The boundaryless theory was proposed by Hawking and Hartel, advocating that the universe has no temporal or spatial boundaries, and its initial state is like a closed four-dimensional sphere, with time replacing the spatial dimension in the quantum state. Superstring theory.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
