Quantum experiment raises a strange question: What if time isn’t real?
Physicist Giovanni Barontini conducted a quantum experiment using Bose-Einstein condensates to explore the nature of time. The study suggests that time may not be a fundamental ingredient of reality, but rather an emergent property resulting from internal interactions within a system.
Why it matters
This research challenges long-standing assumptions in physics regarding the nature of time, potentially bridging gaps between quantum mechanics and general relativity.
The clock or the calendar is not truly required for you to be on time. According to a recent experiment conducted by a physicist, time emerges and changes by itself, regardless of the ticking hands or flipping pages. According to a study published on June 11 in the journal Physical Review Research, Giovanni Barontini, a physicist at the University of Birmingham, conducted the experiment with the aim of answering the age-old question of where time comes from.The problem of timeSome theories suggest that the universe as a whole is static and that time shouldn't exist at all. Barontini set out to look at this problem that physicists have puzzled over for nearly 60 years. The Wheeler-DeWitt equation, a central equation in quantum gravity, the field that seeks to unify Einstein’s theory of gravity with quantum mechanics, describes the universe as a whole system with no external time parameter.
