There probably are still Big Bangs going somewhere, but I've never been into writing epic fics so I don't really keep track. Worth making notes of your idea and then making a post on your journal to ask if anyone knows of any Big Bangs, preferably relaxed ones that don't require betaing.

I hope you can find some. David has been doing nature documentaries for a large part of his life, I think he's in his 90s now and still narrating. He's so passionate about nature. If you like sealife, The Blue Planet is a good one, but I love all his documentaries. I think thee was an episode of... Might have been Life on Earth, it had Sea Slugs, which I adore. They're so pretty.
