•Researchers at the University of Birmingham demonstrated that an 'entropic time' can be derived from the internal dynamics of a Bose-Einstein condensate.
•This internally-defined time successfully ordered events across 44 cycles of expansion and recollapse in a partitioned ultracold gas, establishing time as an emergent property.
•The experiment provides a critical controlled setting for quantitatively testing relational-time theories and frameworks like Wheeler-DeWitt in quantum gravity research.
