Interesting you should ask that, I'm working on what might be a break through in understanding the 4th spatial dimension. I believe the 4th spatial dimension is memory.
Isn't memory associated with the brain? And, isn't the 4th spatial dimension merely a mathematical extension of our known 3 dimensions? How does space have a memory?
In Physics, Electrons, use Imaginary numbers to be found ( I think) so therefor, the Electrons are remembering the object that created the field.
If electrons don't have brains, how can they remember things? What emits the electrons after the physical object no longer exists?
