check out nostradamus if you like that kinda stuff.
nostradamus predicted thousands upon thousands of things.
so ofcourse with enough speculation you will be able to find links between what he said and what has since happened.
and also, when a star dies it doesnt always explode and turn into a supernova. or just burn out into a shell.
the energy has to go somewhere. because if you have read anything about the science of it, you will remember "true energy does not die, and is forever".
this can cause the star to become more dense, and alternatively become a neutron star.
the explosion has also thought to been a viable concept for the creation of a black hole, yet this theory has never been proven.
and another thing to think about when you are stoned is the possibility of white holes.
(ie; the opposite of a black hole, instead of creating an immensly strong vaccuum in space that even light cant escape, it forces light and other matter out, at an incredible force, to strong for any advancement of technology we have to measure.)
but, thats just an idea.
