“Time awakens those who sleep,” a line by the poet Saad Ibn Jidlan, mentions one of the functions of time: awakening those who are heedless. This article discusses time from a physical and philosophical perspective, reviewing the development of time theories from relativity to quantum physics and their impact on our understanding of time and its behavior.

The theory of gravity discarded absolute space and time, with Einstein showing that time varies depending on the observer’s motion and speed, revolutionizing our understanding of space-time. The article also explores quantum physics experiments such as the double-slit experiment, illustrating the dual nature of photons and electrons as both waves and particles simultaneously.

It further discusses Einstein’s general relativity explanation of gravity, where the Sun’s massive mass bends the fabric of spacetime, affecting planetary motion and speed. Scientists believe that traveling to the future is possible, while traveling to the past is impossible due to logical paradoxes.

Finally, the article raises philosophical questions about the nature of time, whether time has a “brain” or free will, highlighting the perplexity scientists face in explaining the behavior of time and elementary particles.
