Being to Hobbes (and the other empiricists) is the physical universe:The world, (I mean ... the Universe, that is, the whole masse of all things that are) is corporeall, that is to say, Body; and hath the dimension of magnitude, namely, Length, Bredth and Depth: also every part of Body, is likewise Body ... and consequently every part of the Universe is Body, and that which is not Body, is no part of the Universe: and because the Universe is all, that which is no part of it is nothing; and consequently no where."
