One possibility to imagine is that for any present that there are a nearly infinite
number of immediately following events depending on actions taken, here visualized
as an infinite set of probability chains or threads from a point in time to the next
for any number of "parallel" spacetimes. So, if the message warns not to break the
cup, and it isn't, then in one spacetime the cup was broken, and the other it was
not. This action might actually generate the alternate spacetimes.

The possibility of alternate realities is not inherently disprovable under
contemporary scientific explanations, at least in the reality from which this
message is posted.
