The Big Bang Theory: 10 Theories On How It Will End
3. Time Jump: Everyone Is Happy With Kids
For a show that has a lot of science and deals with pop culture icons like Doctor Who and other time travelers, it's not much of a reach to think the final episode in the series might take place in the future.
A time jump to sometime in the future featuring the characters from the show might just happen and there are two likely ways it could go. In the first time jump, the main players in the series will be seen going about their lives, but with several kids in tow.
Stuart will be married (along with Raj) and everyone will have kids. Depending on how far in the future the time jump progresses, this could play out rather hilariously when it comes to taking a peek into the lives of Sheldon and Leonard's kids.
The kids will, of course, look like their dads, but more importantly, Leonard's son will be just like Sheldon while Sheldon's little boy will be just like Leonard. They will dress like their dads, which will be part of it, but most importantly, they will act like them, which would be a funny way to play out their great relationship and friendship into a new generation.
