What is the universe?

The

Universe is the totality of everything that exists, consisting of galaxies, star systems, planets, bodies and space. The universe is infinite and constantly expanding. It includes everything we can perceive and what we don’t even know yet.

The birth and development of the universe is a complex process that began with the big bang about 13.8 billion years ago. As a result of the Big Bang, matter and energy were created, which have formed everything that exists in the universe today.

The universe consists of different structures, such as galaxies, which are billions of different sizes and shapes. Galaxies consist of star systems, which in turn contain planets, galaxies and other celestial bodies. Space is full of various phenomena, such as black holes, stars, quasars and dark matter.

Exploring and understanding the universe is still a central goal in astronomy. Astronomers use various observatories and telescopes to study the structure and evolution of the universe. New observations and theories are constantly emerging, and they help us better understand the complex nature of the universe.
