Expanding universe and light detection

[UseAsDirected]

Sorry if this question has been reproduced elsewhere.

If the universe expands greater than the speed of light, c, will a light ray from a distant object never reach us? Lawrence Krauss gave a nice presentation and commented about this, but this has thrown my nose out of sorts because I think light will reach us regardless of frame speed, even a frame traveling greater than c oppositely.

Thanks for reading.

The velocity of a distant object is given by Hubble's law
v=H_0 d
where v is velocity, d distance, and H is a constant. The distance at which v=c marks the Hubble limit--more or less the event horizon--beyond which we cannot be causally connected. No, light will not reach us.
