neither mathematics nor information appears to be the product of the 4D block

Math is entirely a priori, that is, a product of our noodles and can neither be proved nor disproved by appeal to empiricism.

Thank you for your reply! That is one view, the Aristotlean mathematics view - but there is another view, the Platonist view.

For Lurkers: under the Aristotle view, the mathematician invents the math - under the Plato view, the mathematician discovers the math, e.g. pi exists and was only discovered.
