Physicists have long grappled with understanding the nature of time. However, a new theoretical study proposes that time might actually be an illusion, emerging at the quantum level. According to this study, time may not be a fundamental aspect of the universe but rather a product of quantum entanglement.
The nature of time has always posed challenges for physicists, as its inconsistent behavior across the leading theories of the universe has hindered progress toward a "theory of everything" — a unified framework for explaining all of physics.
In this new research, scientists believe they may have uncovered a clue: time could be a byproduct of quantum entanglement, the mysterious link between particles separated by vast distances. The team published their findings on May 10 in Physical Review A.
Lead author Alessandro Coppo, a physicist with Italy's National Research Council, told Live Science that "there is a way to introduce time that aligns with both classical and quantum laws, and it arises as a manifestation of entanglement. The correlation between a clock and a system leads to the emergence of time, which is crucial to our lives."
