Could entropy be relative to a vector?

Just out of curiosity, could the manner in which we experience time, the patterns of entropy and all that good stuff be a side effect of the big bang's outward impact through space/time in which, with our perceptions being limited to this small sphere of space/time effectively appear "linear" due to how small that range is?

To elaborate, lets say the big bang occurs and space/time and all matter and goodness goes flying out in every direction, in space and time. We exist at a location a certain distance from that center in both space and time. If we could "do a 180" with regards to time and head towards the center of the big bang in space, entropy would appear to go backwards right up to the point we got to the exact time and place the big bang began. If we continued from there, we would suddenly again experience entropy as normal and not backwards, and even though we were still going "back" in time to before the big bang, and we would be traveling through another vector (in time) of the big bang's expansion.

From our perspective here and now, it would look like "reverse entropy" but if you start at the point in time/space of the big bang, along any vector in time/space, you'd experience what appears to be normal entropy radiating out from that center point in space/time.

To that end, the strange way we see stuff glued together in "space" and changing over time with consistent physical laws with an increase of entropy, is just another form of diffusion radiating out from the original point - just that radius is measured as a distance in time.

This is just speculation of course (hence it's here) but I am curious if it is consistent or breaks down with a better understanding of space/time and the big bang than I command.

Any thoughts?
