The title text does not mean the Big Crunch, but merely the fact, that a closed Universe is finite. It's like a surface of a sphere (2D analogy for a 3D world). If you go in one direction for a long time, you make a complete circle and return to the point where you started, but from the opposite direction - hence "the boomerang hits him in the back of the head". If it was a Big Crunch, the boomerang is not guaranteed to come from the back.

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? 199.27.128.65 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. 141.101.99.217 (talk) (please sign your comments with ~~~~)

Bonus strip: Just read the rightmost panels straight down. It still works. Literally. 108.162.215.70 22:26, 28 June 2018 (UTC)
