Reply to comment by 96_doomer in TIL "to pull oneself up by one's bootstraps" is an example of an impossible task. The idiom dates at least to 1834, from the Workingman's Advocate: "It is conjectured that Mr. Murphee will now be enabled to hand himself over the Cumberland river or a barn yard fence by the straps of his boots. by meat-juice

4th time is the charm?

When I say the "4th dimension" I'm referring to time. X, Y and Z let you know where something is -- but, since everything is moving at all times relative to something else, you can't really know a location without factoring for Time.

Anyway, as simple as I can put it; the "time gradient" results in gravity because things closest to a mass are slowed more than the parts of them (and space) that are further away from mass. If it overcomes their movement (inertia), they will get closer together.
