Howcome you can still see supernovas and nebulas through telescopes destroyed thousands of years ago, and it only reaches visbilibily to us now...
If it is destoyed, and doesn't exist how can we still see it?

Light has to travel through space in order for us to see it, just like sound. The distances are so vast that by the time the light reaches us the star has died. No illusion, just maths.1
