It’s always from our PoV.
We have no idea and no way of knowing what’s actually happening 600 ly. away, right now.
All our measurements are based on what we can observe from here.
So if the paper is calculating supernova in couple of decades, it means the star actually went supernova 600+ years ago.
Ok! Thats what i assumed but the other guy said something else. I should have been able to guess based on the fact that nothing is faster than light, but oh well.
