What's the fastest space pulls apart from itself?

  • #1
Physics says no object moves faster than C. Physics allows for space itself, as the substrate for objects, to expand faster than C. My question is how much faster? 2 or 3 times C?

I don't think there's a limit. Theoretically you could crank the dark energy "parameter" up on a hypothetical universe, and get it to expand infinitely fast.

Ok, but given observation isn't there a current observed limit. If I recall correctly, any two objects seperated by a distance corresponding to a redshift of z=1.6 are moving away from one another at C. So what about objects at z=7 and up?

Inflation is the best example, we're talking speed that makes most science fiction look weak by comparison.

There is no effective limit on the pace of expansion. It appears to have been very rapid in the early universe. Bear in mind, however, this assumes the redshift-distance relationship is valid [which is a fairly safe assumption].

Chronos, what limit would you guesstimate based on current observations?

1000x speed of light.
