    I used a rolling pin just to flatten a slab of dough the other day. I started wondering whether one could squash a 3D object so flat & thin that it becomes a 2D object?

    If if so could the process be reversed?

    If you apply enough pressure you can flatten anything but in maths a 2D object has infinitesimal width... unavailable in reality. Reversing the process will be problematical in most cases!

    Figured it can't be done for an object but let's say it as possible to flatten one dimension of 3D space, would 2D space result?

    Too philosophical for me! Ask a mathematician!

    It's not a matter of flattening one of the dimensions; it's a matter of removing it. At long as there is a third dimension, no matter how thin it is, then you have a three-dimensional object. If you encountered a two-dimensional object during the day, you would not see it, as it would have no mass - as we understand it.

    @Whomever;
    Go to Gutenberg.org, there you may download a free pdf of Flatland by Edwin Abbott. (Out or copyright for at least a few years now.)
    This is the first homework assignment for persons wishing to discuss dimension in mathematical or philosophical fashion.
