    I don’t get your concern.

    Cardboard cutout is flat. We set the cutout to be the size of the sun. When the time starts affecting it, yes the gravity tries to collapse it onto the sphere but mass stays the same and gravity exerted “outside” is the same.

          Put a sheet of paper vertical and let gravity do its work. What happens? Then think about a BIG “sheet” that has gravity by itself. You end up with a ball.

            yes:

            1. that ball has 1018 kg mass
            2. that ball falls on earth and burns all the oxygen (debatable) or the cutout falls on earth like a big wrapper and burns evenly.
