Frustration, frustration, frustration:

Just read this from elsewhere, grrrr!

"Time and distance are counterintuitively relative: They change depending on your frame of reference. Moving quickly makes distances shrink and time slow down."

Distances shrink with moving quickly but time doesn't slow down for the mover! Slowing time and saving time are two vastly different physics! The only appearance of time slowing is in the lengthening picture stretching out between a light born imaged traveler receding away into the observable universe of past histories and the real time observer -- and the real time traveler! -- existing in an invisible, un-observable, un -observed, entangled, quantum entangling, spontaneously concurrent (t=0) REALTIME NOW (t=0) eternal instant! The entangled real time traveler, and his real time clock, accelerating in space and time expansion away from both the observer and the light born photo-frames imaged traveler from the observable universe of past histories only, which is all the observer ever observes, or will ever observe!

The imaged traveler and clock are matters of past history, falling ever further behind (thus slowing down in time) into the "time reversed" observable past histories of the "observable universe"! Meanwhile, the real time traveler and his real time clock are dark universe stuff advanced in time as, increasingly, a future history and, all otherwise, no longer relative to the observer (tensor relativity between reals having completely broken down . . . come apart)! If and when he turns around and begins shrinking the distance between his real time clock and himself and the real time observer, the light born imaged traveler will start accelerating in making up distance differences in space and time finally to close the gap, shrink and close the triangle, when the now merged real time traveler and now equally merged real time observer shake hands in essentially the same space (both always having been in the same time period . . . at and passing exactly the same universally concurrently entangled time)!

By simply moving quickly the real time traveler saves time! The real time traveler, regarding space and time, space to time, alone, will NOT slowdown in time by saving time! He, or she, or it, leaps and jumps, and contracts (shrinks), space and time, both at once, by moving quickly!

A fair representation (in a geometry) of the Heisenberg uncertainty principle:

Particularly in this illustrative diagram of it:

1.) If you know position to any certainty, you cannot possibly know velocity to any certainty.

2.) If you know velocity to any certainty, you cannot possibly know position to any certainty.

3.) It applies.
