Zum ersten Mal haben Physiker einen Zeitkristall erzeugt, der direkt von menschlichen Augen gesehen werden kann (Video)

What is a time crystal?

Keep it away from Enik.

>The researchers sandwiched their liquid crystal between glass plates coated with a photoresponsive dye. When they shone particular types of light on the sample, the dye molecules polarized, or changed their orientation, exerting pressure on the liquid crystal.

>This pressure created kinks in the liquid crystal that interacted with each other in a complex series of steps, generating a pattern of motion that repeated for hours, even under changing light and temperature conditions.

>These patterns were observed in the sample as an undulating series of colored stripes.

I wonder if one could manipulate the liquid crystal to a sufficiently fine degree that one could create a simple looping animation. Maybe by stacking multiple such sandwiches to make up different elements or „frames“ (and probably using very thin sheets of glass).

What would be a practical application for this?

> they were initially dismissed by some physicists as a law-breaking concept that risked breaking a key rule of thermodynamics.

Well we wouldn’t want that – would we?
