Does the vacuum have volume ?

[clubman]

Hi there. There is a question which I cant really decide what the answer is.

 

"Does the perfect vacuum have volume ?

 

My answer is: maybe yes. Vacuum is a part of empty space but it is not anything, although vacuum is actually empty space. If we say that vacuum is nothing then it equals to say that 0 is not a number. In this universe where we live there is no such thing as "anything/nothing". Even if the empty space is something, because its empy space if we interpret with the help of syntax (which almost doesnt have anything common with the topic) - the predicate is "is", what does it do ? It is. Who is the subject ? The vacuum, the empty space. It is, it exists. And I think if there was a phenomenon called "nothing/anything" in the universe, it wouldn't be apt to call it "nothing", because it exists, it does the action existance, so it is something. And this topic is 50% physics 50% philosophy

 

On the other hand I consider that the vacuum has volume equal to the volume of the object/geometrical figure where the vacuum is. But here is the quiz - how to measure the volume of something which contains empty space. The question is if there in a particular geometrical figure/object/packing is 100% contens of perfect vacuum then the vacuum's volume in this particular geometrical figure/object/packing will equal to 0 cm³ because vacuum is empty space. And yes its volume is 0 cm³ but this doesnt mean it dont have volume, because zero (0) is a number and the vacuum have volume although the vacuum itself is empty space it exists. Plus that if the vacuum didnt have volume the vacuum itself would have existed at all, but it exists. It is something. It has volume, just the volume is 0 cm^3.

 

 

This theory depends on how we look at the space - if the space is an object then my theory will be truthful but with the small correction that the vacuum has volume which equals to the volume of the geometrical figure/object where the vacuum is and alwayis its volume will be >0 cm³ . And every empty space created by an object will be with vacuum volume which equals to the object's volume.

 

I used cm³ just like that. Perfect vacuum means there aren't any little parts in the vacuum.

 

So what do u think. Please give some replies )

A vacuum can occupy a volume. This is not the same thing as saying it has volume. It's like asking what the volume of water is. We don't know until we describe the container holding it, or alternatively, until we enumerate the mass of the water we're discussing. Since volume does not (to my understanding) have mass, the only way to describe the volume of a vacuum is to use the volume of the container holding it.
