Black hole merger question

[dyqik]

Ha, I also managed to avoid any relativity in my degree.

But did relativity avoid you?

[basementer]

I did special relativity, that's fairly basic and impossible to avoid if you want electromagnetism to make any sense. General relativity is a whole other thing.

Fairly basic as in third year undergraduate.
I took SR, and the necessary underpinnings of electromagnetism, because I'd been fascinated by it for ages. But I wasn't actually good at it. Should have stuck to algebra.
