Speed and / or expansion rate of the Universe?

  1. Jun 16, 2015 #1
    Is it true that the universe itself expands faster than c = 3 × 10^8 m/s at some places / areas / points.
    I have heard it but wasn't able to confirm.
    Because outside of the the universe, there ain't anything as far as we understand and hence the universe should not have to follow any law as far as speed is concerned.
    Can someone clarify please?

    "faster than c" implies that you are equating recession with proper speed. Doesn't work that way. Proper speed is confined to c. Recession veloctiy has no such limit.
    This is not correct. There IS no "outside the universe" so any "rule" you make concerning it might just as well be applied to unicorns.
