I saw a billboard today for an attraction claiming to be in 4D. What is that? Then, I started thinking about how time is often referred to as the fourth dimension (logically, this makes sense to me if you consider dimensions the necessary coordinates to define a thing in physical space). This led me down a mental rabbit hole... if time is the fourth dimension, then wouldnt watching regular film and TV actually be 3D. Watching media on a standard screen, you experience images with height and width, and they exist in time: THREE dimensions. Put on 3D glasses, and you now have height, width, depth and time... FOUR dimensions. #HeadExplodes
