TIME IS AN ILLUSION.

After a long break, that is encompssed by a series of events,I was looking in to the amazing concept of time which we all experience as a flow of events one after the other,each moment in now merging into the past.I always wonder how each moment we spend becomes past in the next moment,and why we can't relive the moment gone or can't see the next moment.Here are certain scientific and experimental observations of the concept of time which I feel like sharing and which I have inferred from the studies I made. " Time is an illusion " The mind bending concept that challenges how we perceive time -- The classical idea of time is that, time is linear and it always moves forward as a continuous flow of events that results in past ,present and future. We have taken one rotation of the earth and one orbit of the Sun, divided into segments and given these segments labels like days, months, years etc. But contrary to this ,in Einstein's groundbreaking special theory of relativity it is proved that time is relative and not absolute.Time expands or contracts depending on the speed and nearness of the person to gravity. For example the time in a clock in the moving train appears to be slow for a person standing still on a platform whereas it appears normal for a person sitting in the moving train. So time slows down for an object in motion relative to stationary observer. This difference in time becomes more noticable as the object's speed approaches the speed of light.Modern physics and quantum mechanics suggest that time is an illusion created by our mind's limited perception.When we wait or when we are stressed time feels very slow, when we are happy or engrossed in something,time feels like it flies,though time itself doesn't change.Our experience of it changes based on our state of mind and perception. If we look at the stars, their light travelled billions of years to reach us now.So the past at the stars is our present. In sleep we experience only an instance has passed between the time we sleep and time we wake up whereas real time has passed in hours.we don't experience time when we sleep,whereas the time continues to flow.So our perception of time is not linear but subjective. Time zones around the world show that time is man made construct to measure passage of events.When it is 5 Pm at one place, it may be 2 Am the next day in another place depending on his position on Earth. There is no such thing as universal clock and time . Time is something our brain creates or perceives .The block universe is a scientific concept rooted in Einstein's theory of relativity that treats all moments in time (Past ,present and future )as existing simultaneously,not as a sequence. This concept treats time as a 4 th dimension like spacial dimensions ( length width, height).It considers universe as a huge block where all the events past , present and future already exist within this block.For example a movie is made up of many frames, all the scenes from the beginning to the end exist on the film simultaneously, but when we watch the movie the passage of scenes creates a sense of time moving forward because the scenes are presented in a sequence creating an illusion of flow.If someone skips the scenes forward or backward,he will experience different scenes. Like how Einstein's theory of relativity suggests that different observers can experience events, in different sequence depending on their frame of reference and observers motion and position. Whatever may be the philosophical, scientific and experimental observations of the concept of time,the idea that there exists no time is difficult to digest as human mind is programmed to believe that ,time is linear flow of events.
