Nice stuff. Mind boggling.

However, these galaxies at the edge of the universe are (now, not when
the light left them) in a part of space traveling away from us faster
than the speed of light. Eventually the last photons will reach us and
those galaxies won't be seen by humans ever again.

(This will take a while however, so don't make popcorn for viewing...)

I don;t think that is true as nothing travles faster than light.
(well other than the wierd nurtrino result which I put down to an
error)

So did they; they finally tracked it down to a loose cable on a GPS unit
(which was being used as their time base too). Even the initial
announcement was clearly "we have these anomalous results we can't
explain, but we don't believe them, please help us figure out what's
wrong", not "OMG! FTL!".

Well, nothing we know of so far is faster than light.... But there are a
few things we don't know....

Tghose galaxies and other will all die out eventually, they won;t be
creating any 'light'
(or very little) of their own.

and the fizz will be gone from your cola too ;-)

My understanding is that nothing can travel through space faster than
light, but that space itself can expand faster than lightspeed.

So if something is traveling at 51% of the speed of light in one
direction, and we are traveling at 51% the speed of light in the other
direction...
