[quote] Yes, I know what 2d and 3d are, but why can't living things be 2d?[/quote] Because atoms are not 2 dimensional. Spheres are the most geometrically stable shape, thus everything in the Universe more or less being a sphere. You can get a tad more technical than that by saying that the perturbations in 4 dimensions which lead to natural phenomenon like atoms necessarily have to be multi-dimensional because of how that 4 dimensional area is influenced by these perturbations. Put simply, something with mass necessarily is breaking spacetime symmetry. [quote] Is light 1d, 2d, 3d, or no d ( ͡° ͜ʖ ͡°) (serious question though)[/quote] Depends on how you look at it, but photons are zero dimensional. [quote] Is darkness the same?[/quote] No such thing. Darkness is a lack of light. Just like how coldness is a lack of heat. [quote] Can a 3d object go into the second dimension, as of yet? And 2d to 3d?[/quote] Dimensions are not different realms. A dimension is a measurement. Adding a dimension implies a perpendicular measurement. [quote] What dimension are black holes?[/quote] The singularity is 0 dimensional, by we don't like to talk about that, so we can describe the event horizon as a 3 dimensional sphere about the singularity.

What dimension are black holes?[/quote] Cellular life is in 3d but depending on your definition life can be 2d (or hyper dimensional but then the maths and physics people will debate how many is the maximum reasonably). Light...is an electromagnetic wave which we perceive as propagating in 3 dimensions for movement and fields, but really that doesn't mean it isn't a subset of high dimensions. The darkness...is that thing we fight in a video game most of us on these forums probably. Black holes...is a topic where there is no 100% answer on all its properties though it does "consume" mass and release radiation making it sort of a recycling machine for "frozen energy" if you will. Of course that's a bad explanation too. I need sleep...I was just planning on posting stupid answers and cat memes.
