Searching for dark matter

Although dark matter does not emit light, it still has mass and can cause spacetime to bend. By observing the gravitational lensing effect, traces of dark matter can be discovered. If there is a noticeable bending of light in an area where there is not enough visible matter to produce a significant gravitational lensing effect, it may be due to dark matter at work.

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.

Dark matter is a theoretically existing substance that does not interact with electromagnetic forces and cannot be directly observed. However, through observations and theoretical calculations of the universe, scientists believe that dark matter accounts for the majority of the matter in the universe. Dark matter affects the shape of galaxies and galaxy clusters through gravitational forces, causing the light of galaxies and galaxy clusters to bend when passing through dark matter. This phenomenon is called gravitational lensing effect. By observing the morphology and distribution of galaxies and galaxy clusters, the distribution of dark matter can be identified.
