Several problems with the science in many comments.
1. The Hubble "constant" is constant across space, but not across time.
That is why the expansion history of the universe is not linear, with a recent acceleration. I mean, how could the expansion rate have started increasing some 5 billion years ago if the expansion rate is always constant?
2. Very distant galaxies can recede from us at a speed greater than c.
The very distant, receding galaxies are not moving through space at a speed greater than c: they are essentially at rest, being carried away by the expansion of space between us and them, and there's no theoretical limit on how fast space itself can expand.
