Default cosmic radio noise

http://www.nasa.gov/centers/goddard/...e_balloon.html
http://www.newscientist.com/article/...rst-stars.html

quote[NASA]: Listening to the early universe just got harder. A team
led by Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt,
Md., today announced the discovery of cosmic radio noise that booms six
times louder than expected.

quote 2[NASA]: A mysterious screen of extra-loud radio noise permeates
the cosmos, preventing astronomers from observing heat from the first
stars. The balloon-borne ARCADE instrument discovered this cosmic static
(white band, top) on its July 2006 flight. The noise is six times louder
than expected. Astronomers have no idea why.


I appreciate all the name calling and hatred in this newsgroup but hey,
why am I relying on gizmodo to keep me abreast of such things? I
thought, likely naively, that is what this place is for.


/diatribe.


So what's the deal here, from someone that is good at explaining such
things to laymen like me? What are some things we, collectively, might
think we're actually hearing? Is this similar to the time when the
scientists thought they had something wrong with their equipment and
were actually listening to the beginnings of the universe... as in, are
we possibly "hearing" something other than what we expect to hear?

Other questions: would this make more sense if we could send the
instrumentation into space? How could we continually monitor such
noises, to see if the boom we hear now will continue in pitch(?) and
duration? Is there anything the layperson can do to lend a hand with
any of this research?

The consensus is that there is one Supernova explosion per galaxy every 100
years or so. Multiply that with the ever increasing number of detected
galaxies, and you are in the neighborhood of one Supernova event per minute,
occurring somewhere in the Cosmos. Could the strange background noise be the
collective echoing the radiation of their death throes??

Hagar off station static is micro static noise. Its like a
radio antenna go figure Trebert

I believe it's far greater, especially once taking into account the
numbers of colliding galaxies thus far recorded, whereas it looks as
though 10% interactions took place. Even at 0.1% interactions is
going to put on quite a show of cosmic radio noise.

The anti-BB GA that's supposedly 250 million light years away from us
is perhaps already having devoured dozens of galaxies, that which in a
few million years from now we'll start detecting and otherwise seeing
those results.
