One idea could be that the characters are stranded on a strange planet after a spaceship malfunction during the Big Bang. They have to figure out how to survive with limited resources and strange alien creatures. For example, Sheldon could use his scientific knowledge to analyze the environment and find a way to purify water.
Maybe in the 'big bang survival fanfic', the gang gets transported to a pre - Big Bang era where the laws of physics are different. They struggle to adapt and survive while also trying not to change the course of history. Penny might use her street smarts to barter with the primitive beings they encounter.
Another plot could be Penny dealing with the challenges of her acting career while pregnant. Maybe she gets offered a role that she really wants but is worried about how her pregnancy will affect it. This could lead to some interesting drama as she tries to balance her dreams and her new family situation.
One interesting idea is exploring the characters' lives outside of the show's main plot. For example, fanfiction might delve into Sheldon's childhood in more detail, like his experiences in school that made him the way he is. Another idea could be alternate relationships. Maybe a fanfiction could explore what would happen if Penny ended up with Raj instead of Leonard.
One idea could be a crossover with 'Star Trek'. The characters from 'The Big Bang Theory' could find themselves on the Enterprise, with Sheldon trying to understand the advanced technology there. Another idea is a crossover with 'Doctor Who'. The Doctor could arrive in Pasadena and interact with the gang, leading to some hilarious scientific debates. And perhaps a crossover with 'Futurama', where the two groups of characters explore different time periods and universes together.
One interesting 'Big Bang Monster Fanfic' could be about the characters from 'The Big Bang Theory' encountering a friendly monster who helps them with their scientific experiments in a comical way.
Sheldon could be the main character. His unique way of thinking and vast scientific knowledge would be crucial for survival. He could analyze situations, come up with scientific solutions to problems like finding food sources or creating energy, and also his stubbornness would add an interesting dynamic as he might clash with others over his ideas.
A fun idea could be that the Big Bang Theory characters travel back in time and end up in the era of the founding of Hogwarts. They could meet the four founders and try to introduce them to modern scientific concepts. This would lead to some really interesting interactions as the wizards are trying to understand things like electricity and gravity.
A really interesting fanfic idea could be that there is a magical world where Big Bang's music has special powers. The Running Man cast gets sucked into this world and they have to team up with Big Bang to defeat an evil force that is trying to silence their music. Along the way, they use the power of Big Bang's music and the Running Man's strategic thinking to overcome various obstacles like enchanted mazes and magical creatures.
A possible storyline could revolve around Bernadette and Howard. Since they already have a unique dynamic, adding a pregnancy into the mix could bring out new aspects of their relationship. Bernadette's strong - willed nature might clash with Howard's more laid - back attitude when it comes to decisions about the baby's future, such as education or religious upbringing, creating some engaging plot twists.
Well, in terms of 'big bang stories', there are those related to the discovery of cosmic microwave background radiation, which is strong evidence for the Big Bang theory. Scientists detected this faint radiation that fills the universe, and it's like an echo of the Big Bang. Also, some ancient creation myths can be considered 'big bang stories' in a sense, as they try to explain the origin of the cosmos in their own ways, although not based on modern scientific knowledge.
A plot could be that Bernadette finds out she's pregnant right before a big work project. She has to decide whether to tell her boss or keep it a secret for a while. It would be interesting to see how she manages both her career and the pregnancy at the same time.
