The Physics of Time

Time, in physics, is often viewed as a dimension similar to space. According to Einstein's theory of relativity, time is relative; it can stretch and contract based on speed and gravity. For instance, a clock on a fast-moving spaceship ticks slower than one on Earth due to time dilation. Additionally, massive objects, like planets, warp the fabric of space-time, affecting how time flows nearby. Essentially, time isn’t a constant, but a flexible aspect of our universe influenced by motion and gravity, shaping our perception of the past, present, and future.
