Supernova of Kepler - 20 000 light years away?

New blog on the kid: Deflating a Star Size, Again, or Two · What Would an Astrophysicist Object, and Why Don't I Buy It? · Supernova of Kepler - 20 000 light years away? · Crab Nebula · Creation vs. Evolution: "Beams of Distant Starlight" · But of Course Astrophysics is a Science, Right ...?

Divide that by 20 000 to get at one light year, and then divide that by 365 to get one light day.

What would the real volume have been prior to explosion at that distance and a proportionally 7 300 000 times smaller length, breadth and height, also known as 389 quintillions and 17 quadrillions times less volume?

What does that say about astrophysics, if I am right?/HGL
