Since everyone on offtopic are professional scientists... Yes, I know what 2d and 3d are, but why can't living things be 2d? Is light 1d, 2d, 3d, or no d ( ͡° ͜ʖ ͡°) (serious question though) Is darkness the same? Can a 3d object go into the second dimension, as of yet? And 2d to 3d? What dimension are black holes?
