The word "space" in Greek language means "peace", "universe". From the Greeks, the word "space" has passed into modern science, as a synonym for the universe. Space includes interplanetary, interstellar, intergalactic space with all the objects within it.   Space - it's a huge space, and it is becoming more and more. All of our solar system is only a small part of the cosmos. Everything that happens in space affects the objects in it, and that is for each of us.
