Does space expand faster than light speed?
No.
That is a qualified no, though, because the universe expanded to half its current size in the first millionths of a second following the big bang, and yes, it did expand faster than light for that one, minuscule instant in time. But since then, it has not.

No, the concept of cosmic inflation describes the fact that space can expand faster than light, but special relativity states that objects in space cannot move faster than light.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
