Why is space a vacuum?
Space is relatively empty, but it is not a pure vacuum. There are scattered individual or pairs of molecules floating around out there, however, they are so few in number and mass that we call it a vacuum. In some parts of space there are massive clouds of gases and from those massive clouds new stars are forming as we sit here typing and reading this paragraph. Now, if you are asking the reason why Space is a vacuum like it is, meaning the cause and effect…I don’t think that there is a real answer for that. It simply exists in that fashion, and has been here a long, long time. It is not possible to date the age of “nothingness,” or trace its origin.
