Thinking about time leads into one of the deepest mysteries in science, philosophy, and everyday experience. These posts examine time as a measure of change, motion, sequence, memory, ageing, and cause and effect, while also looking at its stranger role in physics. From clocks, calendars, and the arrow of time to relativity, time dilation, black holes, quantum theory, and the possibility of time travel, time remains one of the most familiar yet least fully understood parts of reality.
