# Can a region of space-time be viewed as a particle with properties of it's own? [duplicate]

Can a piece of space-time having 3 spacial dimensions and 1 dimension of time be viewed as a particle? Could this piece of space-time have properties of its own (mass, spin, charge) independent of the energy that it coexists with? How small would it be, and how much mass does a "volume time" of space time have? Like, say a $$light second^3s$$?. Also, since time can be measured forwards or backwards could you have a -$$light second^3s$$
