Physics of time

Time is a dimension similar to space, integral to our understanding of the universe. In physics, time is often viewed through Einstein's theory of relativity, which shows that time can warp depending on speed and gravity. For instance, time moves slower in stronger gravitational fields or at high speeds, a phenomenon known as time dilation. This means that two observers can experience time differently based on their relative motions or positions. Essentially, time is not a fixed flow but a variable aspect of the fabric of space-time, shaping how we experience and measure events in the universe.
