I may have to stop talking about sub-atomic physics as 'Alice in
Wonderland' territory, and invoke Cinderella's glass slipper instead.

I sense Derrida and Planck are going to collide quite soon now.

There could be an interesting puff of something resembling smoke.

The non-imaginary world inhabited by unwitting devotees of ontological
realism will shrug its shoulders and carry on.

“All crystals are a solid whose atoms or molecules are regularly
arranged into a particular structure in space.

And it is the same with space-time crystals: however, the recurring
structure exists not only in space, but also in time.

The smallest components are constantly in motion until, after a certain
time, they re-arrange themselves into their original pattern again.

Periodic pattern consisting of magnons is formed at room temperature

A team of researchers has succeeded in creating a micrometer-sized
space-time crystal consisting of magnons at room temperature. With the
help of an ultra-precise X-ray microscope, they were able to capture the
recurring periodic magnetization structure in a movie. The research
project “Real space observation of magnon interaction with driven
space-time crystals” was published in Physical Review Letters:
