I admit that I do not have much knowledge pertaining to relativity and space expansion, however I do know that all speeds are relative excluding light.
This makes sense to me, however a new article published says that "Space itself is pulling apart at the seams, expanding at a rate of 74.3 plus or minus 2.1 kilometers (46.2 plus or minus 1.3 miles) per second per megaparsec".
I don't understand this, as I thought that there couldn't be a universal constant at which something is transpiring at, excluding light.
Perhaps space is just like light and does not have a relative speed but rather a universal speed. Again, not informed on issues concerning the subject but just that's what pops up in my mind.
I know that you are probably tired with mainstream articles but this is where I derived the quote from: http://www.space.com/17884-universe-expansion-speed-hubble-constant.html
