The novelette was adapted into a radio play written by Mark Shanahan (with Paul Levinson and Jay Kensinger) in 2002, and performed at New York City's Museum of Television and Radio. In addition to being nominated for the Edgar Allan Poe Award for Best Play, the radio play was later recorded and released as an audiobook by Listen & Live/Audible.com in 2004.
"The Chronology Protection Case" was also adapted into a student film by director Jay Kensinger, which premiered at the I-Con SF Convention in 2002, and was later released on DVD by MODVEC Productions.

"The Chronology Protection Case" extrapolates from Stephen Hawking’s chronology protection conjecture, and posits a vengeful universe that seeks to protect itself from time travel by killing any scientists who discover or even begin to understand how to do it.
