What Is Space?

This section provides a quick introduction of space, which is a property of our universe that gives us a sense of the size of an object and the distance between two objects.

What Is Space? Space is a property of our universe that gives us a sense of the size of an object and the distance between two objects.

Space helps us to define the size of an object by measuring how much space the object occupies. A "larger" size object occupies more space. And a "smaller" size object occupies less space.

For example, if we put a mouse next to an elephant, we can see that the elephant occupies more space than the mouse. So we say that the mouse is "smaller" than the elephant.

Space also helps us to define the distance between two objects by measuring how much space is there between the two objects. A "longer" distance means that there is more space between the two objects. A "shorter" distance means that there is less space between the two objects.

For example, if we look a pile of wind turbines, we can see that the distance between the first turbine and the second turbine is "shorter" than the distance between the first turbine and the third turbine.
