I begin with chapter 5 of the book. The main question this chapter attempts to address is that of time; does time in fact flow? I know that all of you are thinking, "Well of course it flows, I mean I feel the passage of time, that is what I'm feeling right?" Well kind of. Not really. It appears that the passage of time that you feel is actually your mind processing the travel between the light emitted or reflected from objects reaching your eyes, in effect your entire perception of time is well in the past. Why am I telling you this, well if you remember from the earlier posts about relativity, space and time are one thing that is spacetime. Now if you remember that you may also remember that we, through motion, create curves in spacetime and so when observers move relative to one another the result is two different and completely valid perspectives on the same events. In essence the totality of their observations are the same, but the shape of the slices through spacetime are different. As most people realize the local impact of these differences in perception are minuscule, but given enough distance the effects can be staggering. If you were to take into account the infinite nature of the universe and all the perspectives there in, it is found that while the totality of spacetime exists, the flow does not. This is because, by taking into account all the perspectives of the universe, every event in all of spacetime is always occurring now.
Now it is time for a video that was sent to me after I tried to explain all of this and more to my best friend.
"So what you're saying is..."
Now while that video is decidedly not scientific, it has a point, time is made of stuff. That stuff is refereed to as moments
