24,000-atom mini universe demonstrates time flow without a clock
What if time isn’t woven into the fabric of reality at all? A new experiment suggests that the past-to-future march we experience every day could arise from the internal dynamics of a system. Using 24,000 ultracold atoms, scientists built a “mini universe” that allowed them to study how time might emerge without relying on clocks. The findings, published in Physical Review Research, offer researchers a new way to test ideas that have long remain…
The disorder in the quantum system becomes its own clock and thus confirms that time does not have to be an external constant.
Time without a clock? Researchers create a mini-universe of 24,000 atoms and show how an internal time can arise from changes. The article Researchers create mini-universe and measure time without a clock first appeared on ingenieur.de - Jobbörse und Nachrichtenportal für Ingenieure.
