[quote]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?[/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.
