'Time doesn’t exist': Groundbreaking physics rewrites the rules of the universe

Illusion Unveiled

It is argued by theoretical physicist Carlo Rovelli that time, as we perceive it, is an illusion shaped by limited human understanding and quantum uncertainty.

Relativity Expanded

Rovelli extends Einstein’s space-time by proposing that even relativity’s flexible time is a simplification, with no fundamental "clock" governing the universe.

Event Web

Reality, according to Rovelli, is a web of events, not particles or fields. Time arises from relationships between these events, not from a universal flow.

Entropy Flow

Our experience of time is tied to entropy, the measure of disorder. As entropy increases, we perceive a past and future, linking time to thermodynamic principles.

Quantum Gravity

Loop quantum gravity (LQG), co-developed by Rovelli, dismisses time as fundamental. The Wheeler-DeWitt equation describes a timeless universe shaped by causal interactions.

Causality Emerges

Rovelli compares reality to a storm—a collection of occurrences. Time’s apparent flow is the human interpretation of sequences of causally related events.

Philosophical Shift

Theories like Rovelli’s challenge long-held beliefs, forcing society to reconsider how it organizes life around an emergent, rather than absolute, concept of time.

Critic Concerns

Skeptics argue that core concepts like the quantization of space-time in LQG lack experimental proof, casting doubt on the absence of fundamental time.

Enduring Debate

Rovelli’s "The Order of Time" opens new questions in physics and philosophy, ensuring that the nature of time remains a central, unresolved mystery of the universe.
