Toy Universe Experiment Suggests Time Is a Quantum Illusion
Key Takeaways
- Physicists created a toy universe with 20,000 ultracold rubidium atoms divided into bright and dark sectors.
- By inducing quantum interactions between sectors, entropy increased, allowing an internal time to be defined.
- The emergent time matched predictions from the Schrödinger equation, showing time can arise from quantum correlations.
- The experiment builds on theoretical ideas dating back to Nevill Mott in the 1930s and a 2013 experiment with entangled light.
