Different Forms of Time
Time exists in various shapes and people perceive it in different manners. Before the clock was invented, people followed natural phenomena, such as the rising and setting sun. Following circadian rhythms, they woke up in the morning when it was bright, and they went to bed when it became dark. They ate food when their stomach growled.
At some point, people started understanding the order of the natural phenomena and calculated it based on regularity of nature - such as flood and drought, changes in weather, and movement of stars. From this, people created the calendar and the clock. Even though there is no start and end of the flow of time, horologists divide time into 12 hours, 60 minutes and 60 seconds. Based on this conception, there is designated time. The earth is divided into 24 time zones. In Einstein’s theory of Special Relativity, traveling faster than the speed of light changes how we age. Even a sub-light speeds, we can actually experience distortion of time when we are on a flight to go somewhere and go across the time zones. Even though there is no physical line on the earth, there are different conceptual times zones make us feel younger or older.
My interests and questions started from here, what if the earth is rotating faster or slower than usual? What if the earth spins around the sun faster or slower than usual?
