A theory has emerged that Stuart Bloom, a character from the popular TV show The Big Bang Theory, may have killed Howard's mother, Mrs. Wolowitz. This theory suggests that Stuart gradually killed her off to inherit the money she gave him to reopen his comic book store.
He also used her affection as leverage against Howard. The theory has some merit, given the timing of events and Stuart's motivations. However, it remains unclear if this theory can be considered canon. Nevertheless, it is an intriguing idea for fans to ponder.
