Extinction events and an astrolabe

[Panwasbipolar]

I'm guessing this requires some difficult and monotonous math so I figure if it has been done, it required expensive computing equipment. But, does anyone know of any info or have participated in a computer astrolabe program that has ran the numbers backwards as to the position of planets and our solar system in the galaxy at the major extinction events of the past?

I'm just really curious about it, thanks.

Hey thanks. Very Interesting read but that graph isn't very comforting if I'm looking at it right.
