is it from our own point of view or its point of view? other guy said the opposite lol. idk what to believe
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 the light and radiation we can observe from here. We have no sensors close to it.
So if the paper is calculating supernova in couple of decades, it means the star actually went supernova 600+ years ago.
Even if we did have a satellite in orbit around Beetlejuice, its data would take just as long to reach us as the light from the star itself.
This relatively business is annoying. I suggest we just get rid of the whole thing and go back to the ether.
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.
Astronomy is done from the observer's point of view.
I might be absolutely wrong though, I don't really know anything... I just checked how far away it is... but if it has gone supernova already, then we might have a chance to see it? That would be amazing.
There is no way for us to have any information whatsoever about an object until the light (ie, information) has reached us. For all intents and purposes, from our local reference frame, it hasn't happened until we observe.it.
well TIL
