List,

A producer of radio shows which are often
heard on various NPR stations, Radiolab.org,
has toured a live stage show presentation on
the K-T extinction. I heard it by accident
and was entertained and informed (that's the
whole idea, isn't it?).

It has interviews with Jay Melosh and other
impact scientists (recorded and integrated
into the live presentation). I recommend it
if impact extinction is your thing. Luckily,
there's a YouTube:

(Isn't there a YouTube of everything?)

The show is called, appropriately enough,
"Apocalyptical." The above link is to just
that portion that deals with the impact and
the "Dinopocalypse," but all portions and
smaller selections can be linked to from
this page:

After all, there aren't too many stage
shows based on the K-T impact and dino
extinction!

They (or rather their recorded scientist
guests) attribute the K-T impactor to the
breakup of the Baptistina Family, but recent
(2011) studies based on WISE (Wide-field
Infrared Survey Explorer) data claim to
blow the Baptistina theory out of the water
(so to speak) or out of the sky or whatever.

"As a result of the WISE science team's
investigation, the demise of the dinosaurs
remains in the cold case files..."

The apparently as-yet-unpublished 2008 paper,
"New Constraints on the Asteroid 298 Baptistina,
the Alleged Family Member of the K/T Impactor,"
by Daniel J. Majaess, David Higgins, Larry A.
Molnar, Melissa J. Haegert, David J. Lane,
David G. Turner, and Inga Nielsen can be
found at:
http://lanl.arxiv.org/pdf/0811.0171v1.pdf

A more "popular" explanation of the ruling out
of the Baptistina Family can be found at:

s-think-other-wise/#more-89050

But the stage-show YouTube is definitely
worth watching. Catch it.
