Scientist creates 'mini‑universe' to measure time without a clock

A University of Birmingham scientist has demonstrated a novel experimental method to measure the flow of time without using a traditional clock, showing how time can emerge from the experiment itself—a significant advance in understanding one of physics' fundamental questions.

This does not prove what time fundamentally 'is' or settle major philosophical debates about time's nature; it is a theoretical model demonstrated in a controlled lab setting, not necessarily applicable to real-world timekeeping or broader physics yet.
