A Physicist Made a 'Mini Universe' in The Lab to Check Time Really Exists
A researcher at the University of Birmingham used 24,000 ultracold atoms to build a quantum mini-universe. The experiment suggests time can emerge from internal entropy changes and moving atomic disorder rather than requiring an external clock. This provides a testbed for theories regarding gravity and the early universe.
What changed
Researchers have experimentally demonstrated that time can emerge from internal system changes using a lab-created quantum model.

Physicist Creates Quantum Mini-Universe to Study Emergence of Time
confidence 95%A researcher at the University of Birmingham used 24,000 ultracold atoms to build a quantum mini-universe. The experiment suggests time can emerge from internal entropy changes and moving atomic disorder rather than requiring an external clock. This provides a testbed for theories regarding gravity and the early universe.
What's confirmed:
- A scientist at the University of Birmingham created a quantum mini-universe using 24,000 ultracold atoms.
- The experiment indicates that time can emerge from entropy changes inside a system.
- The research explores the possibility of measuring time without an external clock.
- The lab setup serves as a testbed for ideas in quantum cosmology and gravity.
Still unconfirmed:
- Time could be a quantum illusion.
- A Bose-Einstein Condensate evolved across 44 cycles of recollapse.
