Essay Abstract
What is Time?. We do not have any clear and concise answer to this apparently simple question. This question has a history as long as that of mankind. Philosophers and scientists have been studying this question for several centuries and essentially remains unsolved. We still do not have a coherent picture of time and it's properties, in spite of several advances in our understanding in the science, philosophy, and in general our knowledge about the universe we live in. The subject of time is an active area of research, which is very clear when we look at the sheer amount of literature that has been collected over the past several years. Several questions comes to our mind when we look at the definitions of time. What is time? Can there be time without events?, Is time continuous or discrete?, Does time flow? Does it always flow in one direction (from the past to the future)? Is time reversible? Is time same for everyone and every where in this universe? Scientists have basically ignored the questions on time and generally holds a view wherein time is part of the four-dimensional continuum. Past, present and future events exists along the time dimension, which is just a one dimensional Real line. In fact, we can see that various properties of time progressively disappear as we move toward more fundamental physical theories. This essay attempts to present our current understanding of the nature of time from a scientific perspective. The primary focus is to address the question of whether science can answer the questions on time that we experience.
