Further Boomerang Difficulties
An eternity later, the universe having turned out to have positive curvature and lots of mass, the boomerang hits him in the back of the head.
Title text: An eternity later, the universe having turned out to have positive curvature and lots of mass, the boomerang hits him in the back of the head.


This comic is a sequel of sorts to 445: I Am Not Good with Boomerangs, as it deals with the same subject manner with the same panel layout.

The first strip shows Cueball throwing a boomerang, which doesn't come back. In 939: Arrow, a boomerang returns to Cueball, which can either be the same Cueball from this comic or another person.

In the second strip he throws another boomerang, which somehow manage to hurt the ozone layer (as indicated by an off-screen voice). This is of course not possible with a boomerang, as it is a layer of ozone molecules very high up in the atmosphere.

The third strip shows Cueball throwing something what appears to be a boomerang, but then Megan enters and reveals that it was their last banana - which she probably had expected to eat since she calls him an asshole.

The final strip shows Cueball throwing one last boomerang, which breaks the frame of the comic, already after two out of the four frames of the first three strips. Then panning down we find the last panel, much larger and suddenly mainly black instead of white. It shows that this time he was actually inside a spacecraft (which resembles an Apollo Lunar Module in a very bad manner), and the boomerang has just broken out through the hull. We see him and the boomerang tumbling out into space with the escaping air after the boomerang. To certain death...

The title text notes that, assuming a theory, that is no longer generally accepted, where the universe has a positive (closed) curvature and lots of mass, the boomerang would, after a (very) long time hit Cueball in the back of his head, as the entire universe will eventually fall back on it-self in the Big Crunch. Before this happens everything will again get pressed close together, and it is during this process that the boomerang finally returns to his frozen but, quite possible, preserved head. (So at least one success in four attempts).

Boomerangs also became a main theme in the interactive comic 1350: Lorenz.

OK, Dgbrt, you clearly know more about the universe's curvature than I do. Now, would you be so kind as to actually explain that rather than play tug-of-war with the incomplete tags? 23:41, 25 February 2014 (UTC)

I took a shot at it. Good enough to remove the incomplete tag? LogicalOxymoron (talk) 23:22, 12 March 2014 (UTC)

Should it be noted that a normal boomerang (a weapon) is not supposed to return? Only a returning boomerang (a toy) returns. Tharkon (talk) 00:47, 14 July 2014 (UTC)

What do you call a boomerang that won't come back ? ... a stick. (talk) (please sign your comments with ~~~~)

Bonus strip: Just read the rightmost panels straight down. It still works. Literally. 22:26, 28 June 2018 (UTC)
