Even though it came to an end in May 2019, The Big Bang Theory remains one of the most beloved sitcoms of the modern generation of television. Its ensemble of geeky characters and relatable storylines - in some places, anyway - allowed it to grow in popularity on a year by year basis.
With such a strong fanbase supporting TBBT, it comes as no surprise that the show racked up its fair share of fan theories along the way. Besides, is a show actually great if it doesn't have a handful of theories surrounding it? In this case, it's even in the name for crying out loud.
What makes these ten fan theories so good, though, is that the more you think about them, the more you think to yourself that they could possibly be true. That's exactly what separates a good fan theory from an abysmal one: the probability of it actually existing, regardless of how bizarre it would make the show look in hindsight.
From shocking family secrets to backgrounds that completely change a character's role in the story, Big Bang Theory fans have given themselves more to talk about than the actual show itself did.
