glass, vacuum of 1×10⁻⁵ Pa
φ200 (mm)

In reality, no volume of space can be a perfect vacuum. Some kinds of molecules, atoms, or elementary particles must exist. In other words, there is no such thing as “absolute nothing” in this world. Thus, the two ideas, existence and absence, indicate the same phenomenon here. Inside the glass, the vacuum state is high (1×10-5Pa), created by a turbomolecular pump, but still there are a few molecules that remain. This means that this space can be said to be “nothing” and “something.”
