Zel'dovich transient

This post has many tedious levels of meaning. * and *.

Normally when you say something's tedious it's actually amusing. in this case you are correct, very tedious. However, I know that you actually love this halo crap. You should be ashamed, and your ass hemmed.

Let me enumerate the levels of meaning. No? Too bad.

1. Zel'dovich transients (errors in N-body simulation initial conditions from using the "Zel'dovich approximation" technique) may, but don't, have some relation to the "missing dwarf problem," which is the paucity relative to simulations in the universe of small "dwarf" galaxies, particularly around the milky way.

2. The dwarf in the picture appears to be a transient, i.e. a homeless person.

3. The dwarf is dark, like the "missing dwarfs" (for some reason, not pluralized with "ves"). (The missing dwarfs may just be dark-matter haloes which have no stars in them.)

4. The dwarf is (not) grilling a pancake, (not) not unlike a "Zel'dovich pancake," a roughly planar arrangement of matter thought to some extent to form in the somewhat early universe.

Well, that's about as interesting as it could possibly get. Point 4 is the clincher. It should go on your research webpage, thus reaching the most deserving audience.

Just a pity the sky wasn't rendered a little more CMBish.

How do you know the pancake cooking figure is a dwarf? Looks Timmy as though it's just a long way away, but otherwise normal in staure. If it is a small contrarian, perhaps it's a midget, or a young bigfoot.

Still, a truly great find. One of the greatest.
