Perhaps the most important news: an international team of cosmologists has
released the first detailed images of the universe in its infancy.
BOOMERANG is a balloon-borne telescope that circumnavigates Antarctica.
Analysis of images from BOOMERANG is already shedding light on some of
cosmology’s outstanding mysteries. The results confirm other recent
findings suggesting that the expansion of the Universe is actually
accelerating, rather than slowing down under the influence of gravity.
They also confirm that the geometry of the Universe is, indeed, “flat”.
Cutting edge cosmology, to challenge the mind and excite that sense of wonder.

Finally, I am going to be out of the office for a while. I’ll get the next
message out, and update , as soon as I can after
