This mystery, and another new mystery, ("coccoons" of
material surrounding giant stars (see newsmax.com -- 3/13
for link) makes me really wonder if our astrophysicists,
and cosmologists , at this time, really have any idea what
really went on in the past(or what's going on NOW for that matter).
There were recently discovered new species of animals in Indonesia,
a new lobster found at deep sea sites, the star "coccoons", the
fact that a second, smaller, and heretofore unknown thymus gland
in the mouse, and now this...what else don't we know?
But it is sure a great challenge to try and figure it out.
Astronomers seem to be having trouble explaining a lot of surprises lately:
