      Playing sort of fast and loose with the definition of "object," aren't they? I generally think of an object as a single item, not a collective. If this is an "object," then why isn't the universe itself an object? And if the universe is an object, then it's necessarily larger than this one.

      Agreed. On a cosmic level we have no way of knowing if the known universe is just a small part of a larger structure. As such, all of the known universe could be "single object", so lets be serious about the way we define things, especially in physics.

      In my opinion, TFA is a load of crud. An "object" is a single item. To use an astrophysics definition, it is a parcel of matter of contiguous structure bound by atomic or molecular forces (but not magnetic or gravitic) incorporating solid or liquid state matter, but not gasses or plasmas.

      Following this definition:

      • Earth is an object, but its atmosphere is not part of it.
      • The outer gasseous atmosphere of Jupiter is not part of the planet itself, which is made up of liquid and presumably solids as well.
      • When the Sun casts off gas in solar flares, that gas ceases to be "part" of the Sun.
      • A full baloon is an object that does NOT incorporate the gas it contains.
      • Many have spoken of "escape velocities" being the tie that causes an object to become "one" with another. BS BS BS. The Earth and its moon are not one object, nor are the Sun and the Earth.
      • Dust is a collection of very many tiny objects. Yes, its a little hard to think of a "dust cloud" as many small objects, but thats the way it is, so deal with it.

      Stop with the hyperbole already. A collection of galaxies and gasses and the missing brains of Slashdot readers is not a single object. Calling it one is just an excuse to attract attention to a "hey my discovered object is bigger than yours" competition.

      Well, maybe. But there are a number of examples where it turns out to be very useful to treat a collection of physically disconnected objects as an object. The most common example in astronomy is probably a galaxy, which in many respects acts like a single, organized "object", despite the fact that it's actually trillions of separate objects loosely bound by gravity. And we usually treat our Solar System as an object (which contains four smaller objects of similar structure).

      My favorite example is biological. We have no trouble viewing colonial organisms like a sponge or a coral head or a Portuguese Man-o-War as a single "object", even as a single "individual". But biologists have found that treating a hive of bees or ants (or any eusocial creatures) as a single "individual" helps greatly in understanding them. True, these individuals have a lot of physically disconnected bodies. But they are bound by effective communication systems, mostly chemical, partly visual and auditory, and they really do behave as a single colonial individual.

      This mostly just illustrates that our definitions of "individual" and "object" might need a bit of work. And the best definition might vary somewhat depending on your field of study.

      We know pretty well that treating the "Gaia" concept as a real individual is mostly just silly. But that's at the high extreme; a single animal such as a human certainly is an "individual" although we arose from what was originally a colonial collection of single-cell organisms 600 million years or so back. Somewhere in this continuum we find borderline cases like ants, bees, termites, and mole rats, which are borderline cases that confound our definitions.

      But the universe doesn't have to file things according to our definitions. Rather, it's up to us to find concepts that work, and give them names that work.

      It's likely that, for astronomers, it will turn out useful to treat this collection of galaxies and assorted other stuff as a gravitationally bound "object". Or maybe, like the recent discussion of the term "planet", astronomers might decide that this was a bad idea and will revise the terminoloy appropriately.

      I think they'd have been better off calling it a "structure". But IANAA.

      If you hunt down the actual article, they've also been able to see huge formations of gas from which the galaxies formed (presumably), so the structure includes more than just close-packed galaxies:

      "A team of astronomers using the Subaru and Keck telescopes on Mauna Kea has discovered giant, three-dimensional filaments of galaxies extending across 200 million light-years of space. These filaments, which formed a mere 2 billion years after the birth of the universe, are the largest-known structures ever discovered. They are studded with more than 30 large concentrations of gas, each up to ten times as massive as our own galaxy. These giant gas clouds are probably the progenitors of the most massive galaxies that exist in the universe today.
      [ ... ]
      The Subaru observations were successful in finding much fainter objects than previously discovered in this region. (Figure 4) For example, they found 33 new large concentrations of gas along the filamentary structure extending across 100,000 light-years. This is the first time that so many large concentrations of gas, known to astronomers as Lyman alpha blobs, have been discovered in the distant universe.

      Astronomers think that such Lyman alpha blobs, named so since they are seen in the Lyman alpha emission line of hydrogen, are probably related to the births of the largest galaxies. In the "gravitational heating" model, the blobs are regions where gas is collapsing under its own gravity to form a galaxy. The "photoionization" model attributes emission from the gas to ionization by ultraviolet light from newborn stars or a massive black hole. The "shock heating" or "galactic superwind" model hypothesizes that the glow of the gas is caused by the death of many massive stars born early in the history of the universe, living out short lives, and then dying in supernova explosions that blow out surrounding gas. Team members Yoshiaki Taniguchi and Yasuhiro Shioya (Ehime University) have been advocating for the galactic superwind model.

      Observations with the DEIMOS spectrograph at the Keck II telescope revealed that the gas inside the blobs move with speeds greater that 500 kilometers per second (300 miles per second). The extent of the gas concentrations and the speed of the material within them suggest that these regions must be up to ten times as massive as the Milky Way Galaxy."
