"To illustrate the difference between the two views of time, Sorli and Fiscaletti consider an experiment involving two light clocks. Each clock's ticking mechanism consists of a photon being reflected back and forth between two mirrors, so that a photon's path from one mirror to the other represents one tick of the clock. The clocks are arranged perpendicular to each other on a platform, with clock A oriented horizontally and clock B vertically. When the platform is moved horizontally at a high speed, then according to the length contraction phenomenon in 4D spacetime, clock A should shrink so that its photon has a shorter path to travel, causing it to tick faster than clock B."
Imagine a long line of vertically oriented clocks, all of them STATIONARY. Clock A (oriented horizontally) remains on the moving platform and passes the stationary clocks at a high speed. If clock A ticks faster than the stationary clocks, as Sorli and Fiscaletti suggest, then the travelling twin from the Twin Paradox scenario will return older than his stationary brother. That is, special relativity predicts that the travelling twin will return both younger and older.
FINAL SOLUTION OF THE TWIN PARADOX: When the light clock of the travelling twin is oriented horizontally (parallel to the direction of motion), special relativity predicts that the travelling twin will return older than his stationary brother. When the light clock of the travelling twin is oriented vertically (perpendicular to the direction of motion), special relativity predicts that the travelling twin will return younger than his stationary brother.

DIVINE EINSTEIN: No-one's as dee-vine as Albert Einstein not Maxwell, Curie, or Bo-o-ohr!

We all believe in relativity, relativity, relativity. Yes we all believe in relativity, relativity, relativity. Everything is relative, even simultaneity, and soon Einstein's become a de facto physics deity. 'cos we all believe in relativity, relativity, relativity. We all believe in relativity, relativity, relativity. Yes we all believe in relativity, relativity, relativity.
