Time is not real- it is a human construct to help us differentiate between now and our perception of the past, an equally astonishing and baffling theory states. The concept of time is simply an illusion made up of human memories, everything that has been and ever will be is happening right now. That is the theory according to a group of esteemed scientists who aim to solve one of the univere's mysteries. Most people do not even consider the concept of time but there is nothing in the laws of physics that state it should move in the forward direction that we know. The laws of physics are symmetric, ultimately meaning time could have easily moved in a backward direction as it does forward. Indeed some adherents to the "Big Crunch" theory say time will run backwards when the universe stops expanding and starts contracting back in on itself. This conundrum as to why we interpret time in a forward motion has led scientists to question why. They argue that we live in a "block universe" where time and space are connected, otherwise known as space-time. It describes now as an arbitrary place in time, and states the past, present and future all exist simultaneously. The theory, which is backed up by Einstein's theory of relativity, states space and time are part of a four-dimensional structure where everything that has happened has its own coordinates in space-time. This would allow everything to be real in the sense that the past, and even the future, are still there in space-time, making everything equally important as the present.
