If you could go back in time to observe a moment, what moment would you pick and why?
I'd choose a big medieval battle like Agincourt or something. Medieval times interests me, and I'd like to see the long bows in action. Might pick a battle with Trebuchets though cos they're cool
Assuming some sort of immunity, I would watch the big bang. Sure, most of it will be over before my brain even knows it, but then really cool shit will start happening I hope

I think that would be impossible to observe it tho. Like there was no "space" outside of it to be able to observe it. As crazy as it sounds, the "void" we call space was created with the big bang.
Given we are discussing going back in time 13.8 billion years, and being immune to any negative effects, I think we can go ahead and say that part is figured out by the magic time machine as well.
"being outside spacetime" is probably fine.
Also not a physicist either but that is my understanding as well, there was nothing, no space, no time, no up/down/left/right. And space is still expanding (albeit unevenly) all these billions of years later.
What's it expanding into? Nothing! At least as far as we know. Still waiting to bump up against the next universe bubble.
