Is the universe expanding faster than the speed of light?
It is important to understand that the "speed" of expansion is not through space but of space itself.

In what sense? Can you provide a source for this information?

I get that. But, if the universe (space, time and matter) all began from an infinitely dense singularity; as the Borde-Guth-Vilenkin and Hawking-Penrose-Ellis theorems describe, and the expansion of said universe is not faster than the speed of light- then the light from the distant stars would be reaching us from the beginning of the expansion.
