This article explores Carlo Rovelli's revolutionary ideas on time, drawing from his book The Order of Time and insights from theoretical physicist Li Jianlong. It challenges the conventional perception of time as a uniform, flowing entity, explaining how modern physics, particularly quantum loop gravity theory, suggests that time might not fundamentally exist. The text examines concepts like the relativity of "now", the absence of a universal time, and the lack of directionality in time from a quantum perspective. It further posits that our perception of time's flow is linked to entropy and our subjective interpretation of cosmic changes, ultimately suggesting that time emerges from our human-scale observation of a perpetually changing, event-driven universe, rather than being an intrinsic feature of reality.
