Everything that exists, had existed and will ever exist are all contained within the universe... (Leave out the parallel universes concept for now).. So that means our imagination also exists within the universe.... I mean with our mind we think and our mind is contained within the universe... So the thoughts which the mind produces must also be the part of the universe... The weird part is that the physics laws doesnt work in our imaginations.. I mean that we can imagine a car moving faster than light, we can imagine a drop of water flowing upwards against the gravity and so forth... But we cannot simply say that our imagination is limitless.. Cause it does have some limits like Da Vinci said That quote is quite true.. If you spend some time thinking about it, you will realise it... So my question is that Is there any laws that governs our imagination? Is there any research going on it? Does it belong to just the field of Psychology?
