Here's the information you requested. Both sites are
  - This is the one that demonstrates the
- This one demonstrates that the geometry is Euclidean
(i.e. light unbent by graitation will continue in a
straight line to infinity)

And here is a third article I think you might find
interesting - note especially :

"The best explanation for the observations requires
that over large distances gravity becomes a repulsive
force, not an attractive one."

Yeaaaa! No heat death for us! Now, if we can just
