[–] theKalash@feddit.ch 8 points 3 years ago (2 children) 1.7 million Hiroshima bombs of heat These imperial units are just getting ridiculous. Can someone express that in type Ia supernovas of heat for us Europeans? permalink fedilink source hideshow 4 child comments replies: [–] p1mrx@sh.itjust.works 5 points 3 years ago (1 child) 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. permalink fedilink source parent hideshow 2 child comments replies: [–] theKalash@feddit.ch 4 points 3 years ago (1 child) 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.
