If I induce vacuum in a glass tube and then I open the lid of the glass tube, air rushes into fill in the vacuum. Can vacuum be regarded as a sort of potential energy, able to exert a force? Can a vacuum tube be considered as a potential storage device for energy, just like a container filled with compressed gas can be used as a storage device for energy. Is it possible that vacuum itself is responsible for expansion of universe?
