It has long been suggested that if a three-dimensional object casts a two-dimensional shadow, then a four-dimensional object would cast a three-dimensional shadow. The logic of this however, only works if all 2D objects were shadows to begin with.
|Ever wonder if it were the other way round? What if direction was an optical illusion? What if all 3D objects were just shadows propelled from a 2D realm?|
Then, instead of higher dimensions ejecting downwards, it would be the lower or flatter dimensions bursting outwards. The 4D plane would be a shadow of the 3D world. Light wouldn’t be hurled out by the sun; light would be falling into the sun.
