Why
The experiment aims to test the theoretical idea that time may emerge from relationships and changes within the universe, rather than being a built-in feature.
The Frontline Impact
How this affects you
This research provides a new experimental platform to test concepts from quantum gravity and cosmology in a laboratory setting. It challenges the conventional understanding of time by demonstrating that an internal, entropy-based variable can order events and support quantum predictions, potentially offering new insights into the nature of time in quantum universes.
