An anonymous reader writes "Scientists can't figure out why these rocks — weighing up to several hundred pounds each — slide across a dry lake bed. The leading theory proposes that wind moves the rocks after a rain when the lake bed consists of soft and very slippery mud.

Re:Begs the question

In this case however it's not being used to describe a piece of formal logic, it's being used as a idiom common in English. Like it or not languages are evolved through common usage, not through design, and even though modern English recognizes certain formal rules, idioms, expressions, and colloquialisms are largely exempt from such rules. My usage of the idiom "begs the question" is perfectly valid and is used in this case to mean roughly the same as "raises the question".
