Jumping out of the space-time continuum forward or backwards is an intriguing concept at least since H.G. Wells wrote 'The TIme Machine'. Will space-time travel in that sense occur soon? The answer may be in the perception of what time is for itself. Some believe that it does not exist but is mearly another dimension of space. If that were so shortcuts through space to prior and future space-time coordinates may be developed in time.

Space-time is in perpetual motion and time travel is unavoidable outside of eternity. Within eternity time does not flow. In space-time travel occurs continuously at variable rates in a continuum of space-time. Time is the rate of change of mass compared to other mass and the rate of change comparatively that is has. Everyone is moving forward through time. Time travel perspectives occur in the framework of relative motion; the passage of time occurs in a differential context. Some places are in the future of time relative to another place, while alternatively other places are in the past. What most people mean by 'time-travel' is the possibility of changing one's differential relative time pace and space-time location 'leap-frogging' some-when place else. Thus disrupting, escaping from, short-circuiting, bending, folding, spindling space-time and so forth to step out of the laws of physics would apparently be necessary to travel in time other than within the ways permitted by the prevailing laws of physics.

Einstein pointed out that time and space are dual parts of every object; the faster an object moves through space the less in moves through time and vice versa. An object not moving in space moves more quickly through time, yet time itself can be comparatively arrested in intense gravitational fields perhaps. To move through time in the super-gofast context it would seem necessary to alter space in such a way as to create a channel that bypasses normal space-time relations.

The Australian mathematical physicist Paul Davies wrote a useful book 'How to Build a Time Machine' that considered how space might be bent or channelled in theory to deliver one back to prior points in time. Hypothetically if one could move in space-time to a location that exists before a particular time exists one might be able to drop in on the past. The difficulty is I believe in travelling faster than light and shaping space channels to circle back around to previous points of space-time. The energy required is very significant-and probably
