Where do ideas come from?

Where do ideas come from? Could there be a big bucket out there just filled with thoughts and concepts that filter through a layer of reality that we cannot even imagine?

If Einstein was right, then we know that time doesn’t really exist. It only co-exists with space. That’s why Physicists only refer to time as ‘space/time’. The two are inexorably linked. You cannot have one without the other. Why? Because without one the other doesn’t exist. Space needs time to complete it’s manifestation. Time needs space as reason for being.

Imagine a world without before and after, outside and inside, black and white. You can’t because our relative minds don’t go there. Assuming one dimension is a dot, two a line and three a cube, the natural extension of that progression is four being time. If you hold time constant all events in the past and the future, including this moment--right now, would happen simultaneously creating an implosion or a singularity of all existence into a single Bucket? But then the idea of a bucket is just an idea.

So where do ideas come from?
