Re: Is the universe a set? Probably not.

Some of my points have been touched on by other posters - perhaps
Bruno's comments the wisest, but as usual a little cryptic.

My view of the subject (as enounced in my Occam paper) is that all we
can ever know of the universe is a description of that universe. That
description is most likely to be a set (following Schmidhuber's
universal prior argument).

For example, the very mathematics you use to derive the
indistinguishability of points on a very small scale is based on
a Hilbert space, which is a continuous set.

As for what the universe is really like (Bruno's ontological
question), I remain, as ever, agnostic as to whether it is even a
meaningful question.
