All in all, because of light cones there can be no large-scale growth faster than x^3. And more like x^2 if you want to expand something more than just empty space.

Depends on what the curvature of the universe is. If it's negative then it supports exponential growth.
As far as we've seen, universe seems to be very flat so far.
