    A really painful type of coordinate transformation I once had to develop to try and shed some insight on Hawking radiation near black holes.

    Unfortunately the results were fucking ugly and I gave up trying to understand them, largely due to the fact that except under very specific circumstances they’re basically impossible to calculate (you get something similar to divide by zero errors).

    Nice case:

    Not nice case:

    There was a ton more related stuff I could have spent a PhD working on, but life didn’t really allow it (and frankly I’m okay with that, I’m actually doing enjoyable stuff for the first time in my life instead of fighting my brain).
