Space and time

What is space? Is space real? Where does it take place? Outside, out there in the earth? Or inside? Or only inside? In my head? I move around in my space. Is there a space out there? What is outside? How, where do I perceive it? Do I see something out there? Or is it all in my head, in my brain? Brain? or mind?!

What is time? Does time run like a river? Sometimes gentle and sometimes stormy? Does time pass? Where does it go and where does it come from? I cannot see it and cannot touch it, and yet it is there, I perceive it, it flows (along). Is time tangible or intangible? What happens (in my head) when I perceive time? Is it a comparison? A memory of before, of yesterday, of tomorrow?

Are space and time constants of nature? What is nature? What are the laws of nature? When were they created? Who creates them? Did nature create itself a long time ago? Are they interconnected? Or do I create them in my head, through my thinking?
