Brian Greene: Time Travel is Possible

Is the time we experience in our day-to-day lives real? Here, theoretical physicist Brian Green explores the potential particles of time and why we could, in theory, travel forward in time but not back. 
Greene's area of research relates to String Theory, a candidate theory of quantum physics which attempts to explain the existence of extra dimensions of space. Dr Greene's String Theory not only explains the theoretical potential for time travel, but also examines how different special dimensions might exist and why humans are unable, at this stage, to experience them. Dr Greene suggested that time travel might actually be possible, however, not at this stage in history.

He believes that while it is possible, further human and scientific advancement is required before this dream and world-wide fascination can be realized.
