👉 The time fluid, often associated with the concept of time in physics and philosophy, refers to the idea that time is not a constant, linear progression but rather a dynamic, flexible dimension that can be influenced by various factors. In Einstein's theory of relativity, time is intertwined with space to form spacetime, where its flow can be affected by gravity and velocity. For instance, time moves slower near massive objects or at high speeds relative to an observer. This means that time can stretch or compress depending on the conditions, making it a fluid concept rather than a fixed one. This fluidity challenges our everyday perception of time as a steady, unchanging flow and highlights its complex nature in the universe.
