What does abstract mean?
abstract means a concept with no backing information. A project if you will.
Abstract is the absence of existence. In theory it is real but in reality it is not. Similar to jean Baudrillard theory of simulation vs simulacra. A simulation is like well a simulation. It is the example of the real world. A simulacra is an icon with no existence. Think of it like a concept. It has no backing evidence so it is a simulation the real thing.
