Yep, 'way too upsetting, A-G!
Yet perhaps the 4D block -- 3S + 1T -- can only be viewed as a plane from the fifth dimension (T the second). That way, since we "live" and "perceive" in 4D, we don't "notice" the brane-like quality of 4D. And since we don't "notice it," it is not "real" for us; that is, from our "perspective." Meaning Time is still perceived as linear and unidirectional for us. So we continue to experience time as a movement from past to present to future. And causation appears to be unaffected and unaffectable.
Just a wild speculation.... I'm reminded of Heraclitus' observation: "Nature loves to hide."
PatrickHenry and I had quite a sidebar going on flying "by the seat of the pants." With super speeds, night flying and poor visibility - the pilot has to ignore his 'senses' and pay attention to the avionics.
I believe geometric physics puts the scientist in the same quandary. To understand it, he must ignore his physical senses.
