Let's make a little more interesting: What if you pick 2 answers? 😉

> According to #general #relativity, every #gravitational #wave should leave an indelible #imprint on the structure of space-time. It should permanently strain space, displacing the mirrors of a gravitational wave detector even after the wave has passed.
Since that first detection almost six years ago, physicists have been trying to figure out how to measure this so-called “memory effect.”

> First consider what happens when a gravitational wave passes by a gravitational wave detector. The Laser Interferometer Gravitational-Wave Observatory (LIGO) has two arms positioned in an L shape. If you imagine a circle circumscribing the arms, with the center of the circle at the arms’ intersection, a gravitational wave will periodically distort the circle, squeezing it vertically, then horizontally, alternating until the wave has passed. The difference in length between the two arms will oscillate — behavior that reveals the distortion of the circle, and the passing of the gravitational wave.
According to the #memory #effect, after the passing of the wave, the circle should remain permanently deformed by a tiny amount.

> Chua in his 1971 paper identified a theoretical symmetry between the non-linear #resistor (voltage vs. current), non-linear #capacitor (voltage vs. charge), and non-linear #inductor (magnetic flux linkage vs. current). From this #symmetry he inferred the characteristics of a fourth fundamental non-linear circuit element, linking magnetic flux and charge, which he called the #memristor. In contrast to a linear (or non-linear) resistor the memristor has a dynamic relationship between current and voltage including a #memory of past voltages or currents.

> The #Laser #Interferometer Gravitational-Wave Observatory (LIGO) is a huge installation measured in kilometers that is listening for wrinkles in space-time.

> Gravity causes #space-time to stretch — think back to the diagrams you’ve seen of a massive orb (a star or planet) sitting on a plane with grid lines drawn on it, the fabric of that plane being stretch downward from the mass of the orb. If you have two massive entities like black holes orbiting each other, they give off #gravitational #waves. When they collide and merge, they create a brief but very strong train of waves. Evidence of these events are what #LIGO is looking for.

I'm not sure what do you mean by "les nouvelles coordonees..." but I hope this helps.

Quoting the Bible?

> "Instead of computation, we're putting the computer to work as a new experimental platform to realize and detect new phases of matter."
> "Time-crystals are a striking example of a new type of non-equilibrium quantum phase of matter," says Khemani.
"While much of our understanding of condensed matter physics is based on equilibrium systems, these new quantum devices are providing us a fascinating window into new non-equilibrium regimes in many-body physics."
Modelling their time crystal on Google's quantum technology allowed the team to look for signs of infinite repetition within just a few hundred kicks of a laser pulse. They could also run the simulation backwards and scale its size.
