element

In the early stages of the Big Bang, in the high-temperature and high-density environment of the early universe, protons and neutrons combined to form light elements such as hydrogen, helium, and a small amount of lithium. Over time, stars are born, and within the star, light elements undergo nuclear fusion reactions to form heavier elements, such as hydrogen coalescing into helium, which then coalescing into carbon, oxygen, and other elements. When a supernova occurs at the end of a star's life, it releases enormous energy and can produce heavy elements such as gold and platinum, including iron. It is worth mentioning that there are diamond planets made of carbon elements in the universe, which form under specific conditions and are unique and precious entities in 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.

The origin of elements can be traced back to the Big Bang. In the Big Bang, matter in the universe was heated to extremely high temperatures, leading to the formation of elements. These elements gradually evolved into the elements we see today during the evolution of the universe. Hydrogen was the first elemental substance to evolve from energy after the Big Bang, followed by helium. These two elements dominate and are the most abundant in the universe. The aggregation of hydrogen and helium formed the first stars, which were the first stars in the universe. Currently, a total of 118 elements have been discovered. Each element represents an atom, with different numbers of protons, neutrons, electrons, and other elements inside. The most abundant element in the universe is hydrogen, accounting for over 90% of the total matter in the universe.
