At a point (black circle), the lapse function (yellow) shows how far into the future that point will be projected in a unit amount of proper time experienced by an observer initially at the point. The shift vector (red) shows how that point changes coordinates after the unit amount of proper time. The cyan vector shows the new coordinates the point is projected onto. The lower black surface indicates a set of poi...
