There is a recent article at
http://www.foxnews.com/story/0,2933,525695,00.html regarding a nearby star which
may be getting ready to go supernova. (since perception is relative to proximity what we view as just happening has already occurred)
QUOTE from article :It's possible we're observing the beginning of Betelgeuse's final collapse now.
If so,
the star, which is 600 light-years away, will already have exploded — and we'll soon be in for a spectacular, and perfectly safe, interstellar fireworks show.
Are the effects of supernova on the redirection of doors both cosmic and perceptional taken into account when the machine computes probable futures?
All the Best
