Wassamatter is just the liquid form of Doesn'tmatter.  So watermelons would be quite appropriate.

And let's not forget the red-shifted form...Rose Matter.

Hey shiny aren't you forgeting something?

What about the blue-shifted form?

Oh and chelsea, the wassa-matter and doesn'tmatter things seem to just be word jokes, as for the red-shifted matter, he seems to be linking the term with a typical red flower. By the way Shiny, would that be Doppler, Cosmilogical or Gravitational redshift your talking about?

Okay I know this topic is sort of dead and buried, but while I was browsing another site I saw something I thought you guys may be interested in.

Detailed Dark Matter Maps

Summery: Dec 11, 2005 - Even through scientists have no idea what dark matter really is, they're able to see its effect on regular matter, and use this data to build a map of where it's clustered. Astronomers have used the Hubble Space Telescope to map the dark matter in two very young galaxy clusters. Their observations lend evidence to the theory that galaxies form at the densest regions of dark matter.

You can read the full story here.

There was also an interview with the man who created the maps, Dr. James Jee from Johns Hopkins University. The interview can be read here.

The bottom line is, nobody really knows what dark matter is. Many (a majority) of classical physicists believe it exists, because it's existance is required by the classical theories. Since it fills a "hole" in the theory, they can deduce some of it's properties based on the phenomena it has to account for, but this isn't the same as knowing what it really *is* or even proving that it exists.

Other physicists see the failing of classical physics to fully explain things and point to the same hole and come up with even more radical theories to explain it, and usually also attempt to make these new theories reconcile the apparent incompatibility between the relativistic and the quantum level understanding of the world we presently have. The most popular such alternative theory is the various forms of String Theory, but to date string theory isn't an agreed-upon, cohesive set of theories or formula like classical theory is. Lots of people are hopeful that string theory is "thinking in the right direction" but few would claim that it can explain as many phenomenon as accurately as classical theory, at least so FAR.

Ultimately, tho, while most physicsts believe in dark matter, they don't agree at all on what it IS, and while they all have theories and guesses, nobody to date KNOWS what dark matter is.

So, who's to say you couldn't compress it into ultra-dense balls inside a bizarre alien life-form, or liquify it and greatly inconvenience a whole bunch of penguins? Informed people might dismiss it as silly, but they can't *prove* it's completely impossible.

Oh, and one last comment, "dark matter" and "antimatter" are usually only put forward as a way to produce enough ENERGY to power an FTL spaceship drive, with some other even more fanciful explanation for how that drive itself works. Farnsworth and cubert's explanations of the ship going ftl didn't talk about dark matter, and on Star Trek, it's the warp drives that let them exceed light-speed, which the federation happens to power with antimatter reactors.

although, nobody even knows *exactly* what 'matter' is, as long as project called 'science' is only a hypothesis and good way to describe things when you want to manipulate them.there's no way to provide that scientific theories describes "reality" rather than human cognitive condition i.e.
anyway,its funny that lord nibbler produces such outlandish thing!that explains his apetite
