Newfound Blob is Biggest Thing in the Universe
Space.com ^ | 27 July 2006 | Ker Than

Posted on 07/30/2006 8:22:20 AM PDT by Excuse_My_Bellicosity

An enormous amoeba-like structure 200 million light-years wide and made up of galaxies and large bubbles of gas is the largest known object in the universe, scientists say.

The galaxies and gas bubbles, called Lyman alpha blobs, are aligned along three curvy filaments that formed about 2 billion years after the universe exploded into existence after the theoretical Big Bang. The filaments were recently seen using the Subaru and Keck telescopes on Mauna Kea.

The galaxies within the newly found structure are packed together four times closer than the universe's average.

Some of the gas bubbles are up to 400,000 light years across, nearly twice the diameter of our neighboring Andromeda Galaxy. Scientists think they formed when massive stars born early in the history of the universe exploded as supernovas and blew out their surrounding gases. Another theory is that the bubbles are giant gas cocoons that will one day give birth to new galaxies.

The finding will give researchers new insight into what the structure of cosmos looks like at the largest scale.

"Something this large and this dense would have been rare in the early universe," said study team member Ryosuke Yamauchi from Tohoku University.

"The structure we discovered and others like are probably the precursors of the largest structures we see today which contain multiple clusters of galaxies," Yamauchi said.

Isn't that special; you, too, can live in a metagalactic blob.

It's hydrogen mostly. Just a proton and if it is lucky an electron.

Beware of the Blob!
It creeps, and leaps, and glides and slides across the floor,
Right through the door, and all around the wall.
A splotch, a blotch, be careful of the Blob!

Great pic. Ted is so drunk he's not even trying to negotiate the cones and yellow tape. He's just got his bloodshot eyes locked on his car in the parking lot. He probably dragged the cones and yellow tape clear to his beach house.

A caller to the Art Bell Show last night stated that hydrogen is the smallest atom. This is not strictly true. In fact hydrogen is one of the largest. It is the one with least mass, however.

"Something this large and this dense would have been rare in the early universe,"

I think impossible would be the correct adjective. I've never understood how an explosion blowing everything away from its origin can cause some of the things being blown away to be blown together.

All this structure was merely quantum irregularity in the primordial blob, which was smaller than a single hydrogen atom to start with. Now these blobs are millions of light years across: hardly to be thought of as being blown together.

It has an atomic radius of 37pm. The only one smaller is He, with an atomic radius of 31pm, everything else is larger. Oxygen, for example, has a radius of 73pm. I don't know what you are using to determine that it is the largest.

There can be no "irregularities" if you start with a singularity. That is why I do not believe in the Big Bang. If the BB created space there could have been no "blob" prior to the BB. The expanding universe that the BB assumes is a singularity expanding into "creation". I infer that my body is expanding (and not just from my diet ;-) in a like manner. I'm not a "creationist". But I don't buy the BB either.

It wasn't a singularity. It weighed twenty pounds and was very small. It had quantum irregularities that inflation magnified a bazillion times in a small part of a second.

They say that science education in the US has fallen to twelfth place or so in the world. I wouldn't doubt it. There were complaints even in England that they were closing physics departments in English public schools, but it is happening here, too. It's a symptom.

Welcome to the world of feel good education, extreme whacko environmentalism, no kid left behind (dumb down education to the smallest denominator - I had personal experience with this one), teach only "fun stuff", science and math are too hard, and so on.

What's the harm in jokes and pictures about Kennedy, Moore and the rest? It's not as though they prevent discussion. True, they can't answer questions but maybe you can.

I don't understand a lot about this thing--- is it made up of various gases or mostly one sort? Is its density all that keeps it together or is there some other factor doing so? Is it dissipating at all, and at what rate? What's the second largest sort of object?

There is little to break it apart. If anything keeps it together it is gravity, with maybe some electrical forces also, but it is probably expanding along with the galaxies.
