Consider a structure that moves not in space but time, crystals that change shape and move perpetually without energy, and always return to their original state. Such a structure would break the second law of thermodynamics, a cardinal rule of physics.
Yet, in 2012, Nobel Laurette and theoretical physicist Frank Wilczek imagined them, what he called time crystals. Their movement isn’t of their own accord. Instead, a fracture in time’s symmetry allows for them to stay in perpetual motion.
Time crystals move continually due to a “break in the symmetry of time.” These revolve at regular, calculable intervals, illustrated as a lattice continually repeating itself, thus breaking the law of temporal symmetry. Though his equation worked out, Wilczek’s theory was at first dismissed as “impossible,” by colleagues.
” Time crystals would have been born early in the universe’s existence”
A recent paper showed that they might in fact be possible. This emboldened researchers at the University of California, Santa Barbara. Experimental physicists there teamed up with colleagues at Microsoft’s research lab station Q, and outlined how they could prove their existence. Two teams of scientists then followed this “blueprint” and actually made time crystals. The first was out of the University of Maryland in College Park, led by Chris Monroe. The other was at Harvard University, led by Mikhail Lukin.
Time crystals, according to Wilczek, would have been born early on in the universe’s existence during its cooling phase. Studying these crystals might offer clues to the origins of the universe and how it evolved. It may even revolutionize our understanding of the space-time continuum. Wilczek said in one talk that discovering time crystals would be like discovering “a new continent.” He added, “A New World, or Antarctica, time will tell.”
