No worries. I think it's a thought experiment at best anyway, I mean who the hell can experimentally confirm how a photon views the universe?

I think GR interests me more than QM if I'm honest. I've been watching some particle physics lectures by Michel van Biezen on youtube and once we get to lectons and isospin all that stuff it just fries my brain. I have a hard enough time trying to figure out what the hell the weak and strong forces are. But gravity, I feel like I can follow along with GR without my head melting.
