This term was first used by Pythagoras, a Greek philosopher of the sixth century. Mathematician who discovered the Theorem that bears his name and founder of the philosophical-religious movement known as Pythagoreans.


On the other hand, “universe ” is defined as everything that exists and includes all matter and energy, earth, and all that it contains, along with extraterrestrial or celestial bodies like galaxies, stars, meteorites … “It is everything that existed exists and will exist. ” It has the following elements, namely; space, time, emptiness (this is in discussion), matter and energy.

The concept of universe was developed by the ancient Greeks; this term comes from the Latin word “universes”, which means “all together or integrated”, which was first used by Cicero.

The words “cosmos” and “universe” are used as synonyms, since they refer to the same concept that is the world or nature. But the concept of cosmos is broader and involves more elements than the universe.
