These imperial units are just getting ridiculous. Can someone express that in type Ia supernovas of heat for us Europeans?
Type Ia supernova: 10^44 joules
Hiroshima bomb: 63 x 10^12 joules
So 1 coal mine is around 10^-24 supernovas, or 1 yoctonova.
To be honest, I won't double check that at all, but will just assume you put at least 10 minutes of effort into this.
I love you.

Zero supernovas of heat.
I see that you are a cosmologists.
Haha. Don't have to be a cosmologist to round that one.
I'll thank you just for getting it. I'm not a physicist, but my dad and a lot of my close friends in my youth were. I'm so glad that the general "well you're cosmology, doesn't matter if your're off a couple of orders of magnitudes" joke still holds up.
