The concept of 'Now' is an elusive one that has puzzled philosophers and scientists for centuries. Is it a fixed point in time, a continuous flow of experience, or a mere illusion? While there is no definitive answer, contemporary physics suggests that 'Now' may not exist independently of our perception. According to the theory of relativity, time is relative to the observer, and there is no absolute frame of reference. This implies that the present moment is constantly shifting, depending on one's frame of motion. Moreover, quantum mechanics introduces the idea of wave-particle duality, where particles have both wave-like and particle-like properties. In the wave function describing a particle, there is no definite 'Now' at which it occupies a specific location. Instead, the particle exists in a superposition of all possible states until it is observed. These theories challenge our conventional understanding of time and suggest that 'Now' may be a subjective experience rather than an objective reality.
