I used @grok 4 to start exploring variations of Einstein's final notes. Built a physics simulator in PyTorch to start testing theories recursively, inspired by world modeling. You can just run instances of this locally. Been up since the launch building this (open source! MIT)

Also disclaimer this is super new. Can’t guarantee anything yet but that’s why I open sourced it. Let’s discover the secrets of the universe together!

Code for this coming later this week (had to expand the framework a lot based on great feedback from physicists and mathematicians!)
