Tensor and Van and I began began another discussion in the dark energy thread about the expansion of spacetime. Cougar mentioned it as well. I'm specifically curious about the presumed size of the physical (mass) universe and how that relates to General Relativity and the absolute speed of objects with mass.

As I understand BB theory, there is a presumption of gravitational force (associated with mass in GR) at the moment preceding the singularity. This would seem to suggest the presence of mass, and therefore the presence of the tensor fields of GR. In GR however, nothing with mass can travel faster than light, and in no way could the tensor fields ever "expand" faster than light because objects with mass cannot travel faster than light. I'm therefore very puzzled how the universe can be larger than 27.4 billion light years across if the universe in only 13.7 billion years old. What am I missing that allows any object that contain mass to travel faster than light?
