Summary
An experiment using a toy universe made of ultracold atoms suggests that time may be an emergent property arising from quantum interactions, rather than a fundamental feature of the universe. Physicist Giovanni Barontini's research indicates that time could be a quantum illusion that emerges from the entanglement between different parts of a system.
