What would be the science on this event in a book I’m writing?
So I want to write a book called countdown from 500 where suddenly one day the sun disappears and I know enough science to know that it’s 8 minutes and 20 seconds but I have a few questions. 1. Could something like this happen suddenly or do I have to make a fictional event? 2. Is earth with no sun habitable for any amount of time? 3. What would happen to anyone on the surface when it disappears and how long would it take for the earth to like freeze over? Thank you science community🙏
