It's a well known fact that our universe is, as far as we know today, four dimensional space-time continuum with three spacial coordinates and the time playing a role of the fourth one. We are perfectly capable of traveling backwards and forwards within first three spatial coordinates, but is it possible to do the same on the fourth one? I am sure you would agree that it is not too exciting going up or down or left or right but traveling through time could be something special. But, is it possible? Let's explore all the theories, share some stories and read about one connected hoax.
