Physicists created a tiny universe where time emerged without a clock
Physicists at the University of Birmingham have created a quantum system that demonstrates how time can emerge from the internal relationships of particles rather than an external clock. Using ultracold atoms, the experiment simulated a mini-universe to test theories about the fundamental nature of time.
Why it matters
This research provides experimental evidence for theoretical physics models suggesting time is not a fundamental feature of the universe, potentially reshaping our understanding of reality.
A physicist at the University of Birmingham has created a laboratory "mini universe" that brings scientists a step closer to answering one of the biggest questions in physics: What is time?
