So long Michelson–Morley

According to Science Alert, every year, scientists make adjustments that improve the precision of these devices. Now, they’ve achieved new performance records, making two atomic clocks so precise they could detect gravitational waves, those faint ripples in the fabric of space-time.
Both of the new record-breaking clocks are based on ytterbium atoms. In each clock, an optical lattice made of lasers holds a thousand of these atoms immobile. These lasers excite the electrons of the atoms, which then oscillate, switching with incredible regularity between two energy states.
Like the ticking of an analog clock, this energy switching can be used to keep time – but with much greater precision than any analog or even digital clock. The most recent record-breaker, released last year, was so precise it would keep time without losing or gaining a second for 15 billion years.

Let me see, measure clock ticks  along the north/south axis. Then measure the ticks in the East/West.No difference? Evidently yes there is difference, if they are measuring gravity waves.  The 'fabric of space/time' is the ether, it is the quants of vacuum squished together with no empty space. No one is messing with space or time, they never existed except in the heads of brilliant engineers. Fake, invented variables. With no empty space, you have no clear Euclidean grid.
