>>11409366the expansion of the universe actually can be faster than the speed of light. in fact as we understand, the expansion rate is proportional to distance, so if you go far enough out it starts expanding faster than light and continues to increase linearly after that.
what obeys the light-speed speed limit are causal signals. that's why no signals can reach us from those regions of space that are receding faster than light. that is what sets the limit on where the "observable" universe ends, but there is much more beyond that as far as we understand
