Birmingham physicists create 'mini universe' where time emerges from quantum changes

Scientists at the University of Birmingham used 24,000 ultracold atoms to build a tiny "mini universe" and demonstrated that the flow of time can emerge naturally from changes within a quantum system, with no external clock required. The experiment supports the hypothesis that time is not an absolute feature of the universe but an emergent phenomenon arising from internal change. The findings could reshape fundamental understanding of time in quantum physics.
