Yesterday, I talked about the Avicenna’s Flying Man experiment. It seems quite a strange thought experiment. But let’s modify it and try to come up with a better conclusion.
Imagine pure space with no objects – including no you, the observer – within it. Nothing. No matter. No energy. Nada.
Even if you, by some impossible reason, can be an observer within this space – let us call you, The Insubstantial Eye – you cannot “know” space. You have no points of reference. Even if you move “through” space you will not know whether you are moving or whether you are stationary.
In other words, space is not knowable without objects. This is what I mean by space is inferred from the relationship of objects.
