Cosmos has billions more stars than thought

PARIS (AFP) – Astronomers may have underestimated the tally of galaxies in some parts of the Universe by as much as 90 percent, according to a study reported on Wednesday in Nature, the weekly British science journal.

Surveys of the cosmos are based on a signature of ultraviolet light that turns out to be a poor indicator of what's out there, its authors say.

In the case of very distant, old galaxies, the telltale light may not reach Earth as it is blocked by interstellar clouds of dust and gas -- and, as a result, these galaxies are missed by the map-makers.

"Astronomers always knew they were missing some fraction of the galaxies... but for the first time we now have a measurement. The number of missed galaxies is substantial," said Matthew Hayes of the University of Geneva's observatory, who led the investigation.

So much for that ‘dark matter’ silliness.

Science is a constant learning process . . . they say.

Guess that wasn’t settled science.

At least in cosmology they try to correct their mistakes instead of institutionalize them.

Underestimated by beelions and beelions.

That was my first thought. All that matter they "found" makes up for the amount of matter they thought was dark.

You read my mind!

But then, “beelions” was all-encompassing I guess.

Just like today’s “treelions” when it comes to national debt.

Ah geez, I knew I paid too much to name that star. What to do when you’re upside down on your star naming investment.

Oneof the more common phrases in science is:

WTF was that?

My wife and I had that exact conversation a few years back when cosmologists first started the whole "dark matter" craze.

"How sure are they that they are seeing everything there is to see? Every time they think they have found the edge, they find a way to look further and find more 'there' out there."

LOL, unless its something a liberal skimmer can make $$ off of then its settled.

Science in this country is mostly run by buffoons who believe themselves to be smart. I love it when they’re force to reassess their dogma.

Duuuhhhh! Every time we get a bigger stronger telescope the Cosmos gets bigger. Only because we can see farther. There may not be an end to the Universe therefor don’t be surprised if we find more stars.

The "craze" is many decades old. For instance, the anomalous rotation rates of galaxies has been known for a long time, and this newest discovery would have no impact on that.

" Science is a constant learning process . . . they say "

Here is a news story on Yahoo now....
" They say " that this isle disappeared because of Global Warming, but, the sea levels are only rising in this area, the bay of Bangle .....
I though Global Warming was suppose to raise all the sea levels around the world ? .... how come this area the sea level is rising ? maybe ? it's not Global Warming as " they say " want us to think, but, the tectonic plates under the sea are moving, causing the sea level to rise, that would explain all the earth quakes...
Would the earth's tectonic plate shifting have a effect on sea levels in certain areas around the globe ?

isle in Bay of Bengal disappears into sea
