what is that based on?
- Smashure 4y agoI don’t know where they got that number from. It’s depending on a multitude of factors like, type of supernova and orientation of the supernova (like if we’re in line for a gamma ray burst) *edit For anyone interested in this topic I suggest Phil Plait’s book in the subject
- pencilguin 4y agoI think 5 ly is the range for a supernova sterilizing the solar system if we are not so unlucky to be in a jet. 500 ly is supposed to be equivalent range for a magnetar quake. I think the nearest known magnetar is around 10x that. But even 1% of the radiation needed to sterilize the solar system would be pretty uncomfortable.
