The universe is all of space and time [a] and their contents. [10] It comprises all of existence, any fundamental interaction, physical process and physical constant, and therefore all forms of energy and matter, and the structures they form, from sub-atomic particles to entire galactic filaments.
Universe (stylized as UNIVERSE; Korean : 유니버스; RR : Yunibeoseu) was a Korean mobile app and web platform created by the video game developer NCSoft and launched in January 2021.
The origin, evolution, and nature of the universe have fascinated and confounded humankind for centuries. New ideas and major discoveries made during the 20th century transformed cosmology – the term for the way we conceptualize and study the universe – although much remains unknown.
The universe contains all the energy and matter there is. Much of the observable matter in the universe takes the form of individual atoms of hydrogen, which is the simplest atomic element, made of only a proton and an electron (if the atom also contains a neutron, it is instead called deuterium).

Since the universe has been expanding for 13.8 billion years, the comoving distance (radius) is now about 46.6 billion light-years. Thus, volume ( 4 3 πr3) equals 3.58 × 1080 m3 and the mass of ordinary matter equals density ( 4.08 × 10−28 kg/m3) times volume ( 3.58 × 1080 m3) or 1.46 × 1053 kg .
Jul 4, 2024 · universe, the whole cosmic system of matter and energy of which Earth, and therefore the human race, is a part. Humanity has traveled a long road since societies imagined Earth, the Sun, and the Moon as the main objects of creation, with the rest of the universe being formed almost as an afterthought.
Discover how the universe works, explore how it began and evolved, and search for life on planets around other stars as we seek to understand the universe and.
Jun 2, 2023 · About 13.8 billion years ago, the universe sprang into existence in an event known as the big bang. The early universe was incredibly hot — too hot for even atoms to exist — and extraordinarily dense. As the universe expanded, it it cooled and became less dense. Atoms formed, then molecules.
