Nobel laureate Frank Wilczek first proposed that time crystals might actually exist in 2012. He argued that these hypothetical objects can exhibit periodic motion, such as moving in a circular orbit, in their state of lowest energy, or their “ground state.” Theoretically, objects in their ground states don’t have enough energy to move at all.

But are they just a mathematical curiosity, or could they actually physically exist? And if they do, could they be related to the crystalline objects which feature in Wyken Seagrave’s epic novel?
