Faster Than Light?

This Q, while likely closed now, contains the link for this cut & paste BLOCKBUSTER claim:

The model includes an expansion of metric space that is well documented both as the red shift of prominent spectral absorption or emission lines in the light from distant galaxies and as the time dilation in the light decay of supernova luminosity curves. Both effects are attributed to a Doppler shift in electromagnetic radiation as it travels across expanding space. Paradoxically, while this expansion increases the distance between objects that are not under shared gravitational influence, it does not increase the size of the objects in space. It also allows for distant galaxies to recede from each other at speeds greater than the speed of light: local expansion is less than the speed of light, but expansion summed across great distances can collectively exceed the speed of light.


I learned that NOTHING can exceed the speed of light. What say you? CAN galaxies do it? Does this imply they travel back in time??

Here is a thought, there is only one galaxy out there and we r just looking at reflections of ourselves from long ago. ;)
But time is a relative thing, and humanity's measurement of time is based on our planet movements around its star and really is more of a concept then a natural force. Thats my thought
