Big Bang Theory isn’t just a science idea, it’s a full-on pop-culture language for curiosity. The term comes from cosmology: the universe began about 13.8 billion years ago from a hot, dense state and has been expanding ever since. Then TV turned it into a nerdy love letter with The Big Bang Theory (2007–2019), packed with jokes, fandoms, and brainy pride. I design around it because it lets you wear wonder, humor, and a tiny flex of intelligence. Grab your favorite Clothing and let your inner geek expand.
