Everyday, sun rises at a fixed time in the East and after completing its journey, sets in the West on a stipulated time. The day and night come into existence due to revolving of earth on its own axis in about 24 hours, and in about 365 days, 5 hours, 48 minutes and 45 second’s time, it completes one revolution around the sun.
Time is not an absolute thing. But, the period between two specific events is regarded as time. The time can be felt and perceived when the events stored in the brain arrange themselves in a particular order. Therefore, time is not something concrete, but a sort of perception.
As sense of colors is for differentiating various colors, and sense of taste is for differentiating taste, and as sense of smelling is for differentiating between fragrance and smell, in the same way time is possible balance and possible order of events. Therefore, in 20th century Einstein has put forth the “General Theory of Relativity.”
“Time has no independent existence apart from the order of events by which we measure it.”
As the time is a sort of feeling and perception, it is completely dependent on a perceiver. Therefore there is a relation and relativity between the two. This type of relativity is there in different frame of references. as the colors are meaningless without the visions of the eyes, and as the fragrance is meaningless without the sense of smell, in the same way time is meaningless without the happening of events.
As per the general theory of Einstein –
“Speed of time changes, depending on the speed of the object, and its position in the gravitational field. As speed increases, time is shortened and compressed, and it slows down.”
