In the Arrowverse cross-over event Crisis on Earth-X, when Overgirl went supernova she was dangerously close to the Earth.

A supernova at that point could obliterate even entire solar system including the Sun. How did the Earth survive?

I don't exactly remember who, but Gideon or Earth X's Waverider's AI or someone sciency even mentioned energy of Overgirl approaching Chandrasekhar Limit. So, I have reasons to take Supernova word literally.

    I think it was Mr. Terrific, actually. Not that any of it made a lick of sense.

  • Overgirl's explosion hardly looks like it was at the level of a real supernova, ie a whole star exploding. Maybe a nuclear explosion at best. Hardly a world destroyer. I think the term "supernova" was just an expression to describe "a really big boom". Commented Mar 19, 2020 at 15:24

    Side question: how did Arrowverse's Kara avoid the same fate? It was about her body absorbing too much sunlight radiation.

  • @jhpace1 Just call her Supergirl or Earth-1's Kara.
