Why are his comments in this thread getting downvoted? They show a quite nuanced understanding of S. I. and raise interesting points.
If there is no requirement for the observed data to be at the start of the string that is output, then the simplest program that explains absolutely everything that is computable is this:
Print random digits. (This was actually a tongue-in-cheek Schmidhuber result from the early 2000s, IIRC. The easiest program whose output will assuredly contain our universe somewhere along the line.)
Luckily there is such a requirement, and I don't know how MWI could possibly fit into it. This unacknowledged tension has long bugged me, and I'm glad someone else is aware of it.
I suspect that others downvote private_messaging because of his notoriety. I did downvote his comment because he strayed away from my explicit (estimate the complexity of the Newton's 2nd law) request and toward a flogged-to-death topic of MWI vs the world. Such a discussion has proven to be unproductive time and again in this forum.
Likewise. (With the caveat that I endorse downvoting extreme cases based on notoriety so probably would have downvoted anyway.)
