Does anything exist on a 2 dimensional level?


I understand that one of the 3 dimensions would have to be infinitely small so that it doesn’t exist to be 2-D but does that also apply to light photons and energy?

There is no truly 2-Dimensional thing in the world. At least nothing that has been proven yet. (I think the string theory has “branes” that are, but that is far from experimental confirmation

While any ‘object’ in our world has 3 spatial dimensions there are concepts that are. A surface is 2D, but it’s a philosophical question if the mathematical surface (infinitely thin) is really a thing that exists
