Facts and the future

"Facts do not cease to exist because they are ignored"
Aldous Huxley

Huxley's point is a good one: inconvenient truths, to paraphrase a popular idea, are like the tree falling in the forrest: there is still a sound, even if nobody is around to hear it.

But they are only facts if they are in the past. To quote David Hulett: "There are no facts about the future, only estimates"

So beware: the past holds the facts; the future holds only estimates, and estimates are only known within a range of uncertainty.
