This matches a description I was able to find online. What that seems to imply though is that expansion was literally faster than light. Yes? No?

[edit] and it seems this is true and can be explained by the space-time matrix not being bound by light speed limits.

No. No particle of matter outruns a light ray at the same location and moving in the same direction. Or, to put it another way, all pieces of matter are moving within the light cones at their spacetime locations. "Moving within the light cones" is the correct General Relativity version of "nothing goes faster than light".

The coordinate speed of pieces of matter can be greater than c, but in a curved spacetime that, in itself, is not a problem.


The expansion of space is always faster than the speed of light if you pick any two points far enough apart from each other, at least as long as space is expanding and the universe is infinite. Or if the universe is finite, some time after the bang there will be points which separate faster than the speed of light from each other. These points aren't moving, of course.


Yes it was. I think it's called the inflation period and is used as a possible explanation of why there are big voids in the universe.
