Time crystals

I think this "time" is different from RS time
or is this clocktime (or bs)
I kinda wish RS had a different name for time

World’s first time crystals cooked up using new recipe

Crystals can exist in time as well as space
It’s no longer just a wild theory. Two independent teams of physicists have followed a recipe to build the world’s first versions of an enigmatic form of matter – time crystals.

MIT physicist and Nobel laureate Frank Wilczek first speculated about the existence of time crystals in 2012, while teaching a class on ordinary crystals, such as salt, or snowflakes. In a typical crystal, the atoms or molecules are tightly arranged in regularly repeating patterns in three-dimensional space, resembling a lattice.

Wilczek thought it might be possible to create a similar crystal-like structure in time, which is treated as a fourth dimension under relativity. Instead of regularly repeating rows of atoms, a time crystal would exhibit regularly repeating motion.

Many physicists were sceptical, arguing that a time crystal whose atoms could loop forever, with no need for extra energy, would be tantamount to a perpetual motion machine – forbidden by the laws of physics.

Wilczek countered that a time crystal was more akin to a superconductor, in which electrons flow with no resistance, and in theory could do so forever without the need to add energy to the system. In a time crystal, electrons would travel in a loop rather than a line and occasionally bunch up rather than flow smoothly, repeating in time the way atoms in ordinary crystals repeat in space.

What they are dealing with is faster-than-light motion, which is not recognized in conventional science.

The low-speed side of the unit speed boundary shows objects contiguous in space and discontiguous in time, so there is no repeating pattern over clock time. But once you cross the unit speed boundary, things invert (the reciprocal relation) and structure shows objects (like atoms) that are contiguous in time, and discontiguous in space. That means that the objects may be scattered about (discontiguous) in space, but exhibit a repeating pattern across clock time--just as observed.

Nehru discusses this in detail on his paper on sunspots (Glimpses into the Structure of the Sun, Section 3.2.2), regarding thermal properties of atoms. Keep in mind that thermal motion is inside the time region, so his analysis has the "low speed" range in the coordinate time of the atomic time region, then flips into space. This experiment is just the reciprocal of that (switch the labels "time" and "space").

Nehru actually mentions the crystal grain in his paper:
KVK Nehru wrote:An example of the time region phenomena is the crystal or grain of the solid state—which is of limited spatial extent, but exists continually in time. In the case of the space region phenomena, in view of item No. (iii) tabulated above, the spatial aggregations of the atoms concerned do not persist continually: they keep forming and dissolving into fresh, new aggregates.
Every dogma has its day...
