Seems to follow already from G Drescher's 2006 arguments (see "Good and Real"); the entropic arrow describes the successive displacement of information with respect to location, which was minimal at the Big Bang. Consequently, time points *away* from Big Bang in *both* directions

Maybe the direction of the arrow of time depends on where you are in the universe. Like an expanding 3D space in a 4D space.

The direction of the arrow of time points always away from your memories, no matter where you are in the universe.
