So there is no limit to how fast space-itself can expand? Can space expand at infinite rate?

Hmmm. Interesting. Recent observations say the expansion of space is accelerating. No one knows what is causing the expansion to speed up -- its been given the name dark energy. If we assume this mysterious dark energy stays the same over time (a big assumption since we don't know what it is) and we assume the universe will exist for an infinite amount of time, then I guess this says the expansion of the univere will reach an infinite rate.

Have I missed something here? Comments?

.

The universe is expanding as observed by cosmological redshift - faster than the speed of light, and the speed of expansion is increasing.

 

How exactly is this reconciled with the speed limit of C?

 

 

Here is a proposal:http://www.sciencefo...852#entry675852

There is no need to reconcile. Special relativity says nothing (no information) can travel faster than the speed of light through space. General relativity says there is no limit to how fast space itself can expand.
