(holds tongue... ;-)

But seriously, yes, I believe it. It's still mind boggling. :-) I think 
it's more likely there's something more complex that's well understood 
by people other than me that accounts for the apparently-large results 
from apparently small distortions of space.

Maybe it's just that (a) we evolved with this gravity, so of course it 
seems like a lot, (b) gravity isn't really that strong, as it takes the 
entire sun just to keep the earth in an annual orbit, or something like 
that.

Since GR measures time and space in the same units (modulo "c"), I would 
guess it's well-understood how fast we move in time. :-)

I think I need to dig up my feynman lectures on GR for people who aren't 
physicists again.  (aka "Six not-so-easy pieces")

     It's not feature creep if you put it
     at the end and adjust the release date.
