[QUOTE=Dubslow;457455]The D* non-SM-ness seems to have been debunked (or so I assume having heard nothing about it since) while the K* is currently where the D* was two years ago.[/QUOTE]

I don't understand the deep physics as well as others around here, but my take on it is the LHCb team would be unlikely to continue to publicly discuss this if there wasn't a _possibility_ that there's some "there there".

Possible? Sure. 2 sigma isn't something to be sneezed at. However, as demonstrated 2 years ago, it also is still quite far away indeed from 5 sigma/being an actual confirmation of new physics. So I remain highly skeptical for now, if hopeful.

As you should. As we all should.

Cassini survived the dive in between the planet and the rings- even the un-processed images are looking incredible...

[QUOTE=Spherical Cow;457677]Cassini survived the dive in between the planet and the rings- even the un-processed images are looking incredible...[/QUOTE]I had a chance to talk with Carolyn Porco (head of the imaging team) about 2 years ago. If she had her way, the last orbit or 2 would be around a 1 degree or less inclination. This was only if they were willing to take a big risk for a big reward of imaging ring particles.

That could have been spectacular. Do you happen to know if these dives through the gap were in the original plans back in the 90s when it was launched, or was this a more recent addition to the tour?

Some of the end of life was planned, but not the grand finale like is being done. (Iirc)

Note that the 2nd-most-recent Pleistocene glacial episode, the Riss glaciation, ended ~130,000 years ago – there was a Bering land bridge during that one, too. The approximate ending time coincides with the 130,000-year estimate cited in the above article. Which makes sense, because early in an interglacial would seem optimal for crossing such a cold-climate land bridge - weather warm enough to ease follow-the-food travel and open some ice-blocked corridors, but ocean levels still not risen enough to flood the bridge. But we're gonna need an actual hominid skeleton to settle the was-there-truly-such-an-early-migration issue, then let the debate as to the means proceed.
