True. I was speaking hypothetically. Basically if there even existed an "edge", it wouldn't be able to be observed anyway. So the only correct answer to OP question has to be no.This is partially true and partially incorrect.
It is true that the space between objects can expand faster than the speed of light if they're far enough away. So there are some galaxies we can see that are far enough away that you could never reach them even at the speed of light. The part that's not true is the part about an edge. As far as anybody knows, there is no edge in the first place.
