The Scientific Basis for Time Machines
Space and time are interchangeable (except for our inability, so far, to double back chronologically as we can spatially). So Einstein told us. An interval that one observer sees as a gap in space between two places can be seen just as validly as a gap in time between two moments. It is a truly shocking discovery.
