For the first time astronomers have found a way to get a clean view of
the elusive disks of matter surrounding supermassive black holes.

You've got to be absolutely kidding. They are only now applying
polarized optics in astronomy?


Are they also aware that Earth isn't flat, and that Muslims do not
have WMD?

Polarization filters have been around a long time, Brad.
You can get one for your home scope just about anywhere.
They have several applications.


This is just the first time astronomers realized that they
can use polarization filters to get a clearer look at the
disks that surround black holes.

As I'd said, perhaps they should also be informed that Earth isn't
flat, because that too could make a difference.


Good grief. Isn't polarized optics part of preschool astronomy
duh-101?


Are you saying that the best of our astronomers are mentally slow, and
that others simply don't have a clue?


No wonder their deductive observationology skills are still in the
nearest space toilet.

I think you might be being a little too harsh, Brad. It's
like saying that anytime someone discovers something,
they should be chastised for not already knowing it.

People discover things all the time today that they did
not know yesterday. This just makes them smarter
today than they were yesterday. It does not mean they
are stupid or mentally slow.

Discoveries that bring us closer to a clearer picture of
reality ought to be celebrated and rewarded.

The punishment should fit the crime,
The reward should fit the climb!

happy days and...
starry starry nights!

But every astronomer within Usenet/newsgroup claims to have always
known all there is to know about such optics, and of whatever can or
can not be accomplished. So, why the hell are they better than a half
century out of date?

Years ago I'd asked of using polarized optics, in part on behalf of
KECK being soft-modified so as resolve 1 m/pixel of our Selene/moon.
The polarized application was also along with a green or blue laser
cannon illumination process of our otherwise soft earthshine
illuminated moon.

As of roughly 8 years ago, it seems that I'd also mentioned the NASA/
Apollo usage of polarized optics, of which by rights should have made
our physically dark as coal moon look even darker (of greater contrast
and much less glare factor) to the Kodak eye.
