Our Word is the Projection of a 4D Space A current limit of apprehending the world is the size, mass, density, and speed of light. We observe elemantary particle by light, hence, we can not find any elemantary particle smaller than Poton. We transfer information via the speed of light, therefore, we can not understand some phenomena, such as Quantum Entanglement. Imagine a 3D person in 4D Space We can try to perceive and understand a 4D body based on our experience s that we perceive objects in 1D, 2D, or 3D world. If we lived in a 1D world, how do we appreciate an item? There are no bound between "inside" and "outside". Rebuild a Body through a Stereographic Projection Photo How could we understand We live in a 3D space, however we see and understand this 3D word still through 2D method. Method-1: Transerve Section ss Method-2: Cycling Scaning Ss A Initial Way to Appreciate the 4D Items through Their "Photo", a 3D item. Consci...
