It is a hole because a hole can not be seen but it makes a barrel lighter

But for one to know that this is a hole you have to see something that you will name a ‘hole’ so the part where it says ‘ cannot be seen’ is not satisfactory.

A hole technically can be seen. Therefore, the answer to this riddle is wrong.

I will agree with the answer ” Light” but not laser light which can have force so maybe it weighs something.

What about a flame?
Weighs nothing, can be seen by the naked eye, and it makes a barrel “lighter” if you put one inside of it
